RE: Floodplain Permit Request — Meadow Creek Ranch (MCR) — Stream Restoration &
Stabilization Project.
Dear Mr. Hartmann:
Colorado River Engineering, Inc. (CRE) has reviewed the proposed stream restoration plans
prepared for Meadow Creek Ranch as outlined in the attached Report entitled "MEADOW CREEK
RANCH AQUATIC HABITAT IMPROVEMENT PROJECT, Main Elk Creek, Garfield County, Regional
General Permit 12 Application, July 21, 2017". The report was prepared by Five Rivers, Inc. and
Claffey Ecological Consulting Inc. as part of a permit application to the US Army Corps of Engineers.
The stream improvements will occur along a 2.5 mile reach of Main Elk Creek located
approximately 6.5 miles northwest of the Town of New Castle. The improvements are located
within a land parcel owned by the Ranch (PIN: 2125-142-00-125). Several homes and buildings are
present along this reach of Main Elk Creek.
The project location is not within the Garfield County Floodplain Overlay Zone District. In other
words, it is outside of a FEMA mapped "Flood Insurance Rate Map" or other past studies
completed in Garfield County. However, Section 3-102.A.2.b. of the Garfield County Land Use
Development Code (LUDC) identifies the need to regulate "development" in unmapped areas.
Research of the definition in Section 15 of the LUDC indicates that the stream restoration project
could be covered under the terminology of "development" and therefore, MCR proposes to seek a
floodplain permit approval from Garfield County.
The project improvements outlined in the attached report will restore and stabilize the creek
channel and banks as well as improve the aquatic habitat for trout. CRE has worked with Five
Rivers, Inc. and Claffey Ecological Consulting, Inc on similar projects and have observed that
construction techniques utilized are very effective. Past projects have shown substantial
improvement to the aquatic habitat and floodplain corridor. It is our opinion that a detailed
hydraulic analysis for this project is not needed or warranted because there is not any proposed
development related to housing or other improvements that require the determination of base
flood elevations. This work will result in a net fill of material in the Creek because of the severe
areas of erosion that require stabilization. Riffles, lateral bars, bank toes and coir banks are the
features that require fill below the ordinary high water line; the fill consists mainly of river cobbles.
There will be no increase of the historic floodplain because fill is being placed in areas that have
been severely eroded by recent events. This, combined with removal of berms, check structures,

flattening of bank slopes, and the utilization of riffle and pools will cause a reduction in floodplain
extent and elevations as they currently exist. It is our opinion that the proposed project meets the
purpose of the floodplain overlay requirements as identified in Section 3-102.A of the Garfield
County LUDC. In our opinion, the project will improve the floodplain corridor through the property
as well as have a net improvement to the water quality and aquatic habitat.
Table 3-301 of the LUDC identifies that bank restoration and stabilization are permitted uses within
the floodway and floodplain. Based on our review we believe the proposed work falls under an
administrative review and on behalf of Meadow Creek Ranch LLC request approval of the permit
application
If you have any questions, please do not hesitate to call me at 970-625-4933.

Main Elk Creek Aquatic Habitat Improvement Project
Meadow Creek Ranch
I. Introduction
Meadow Creek LLC proposes a creek restoration and fishery habitat improvement project on
Main Elk Creek on the upper 2.5 miles of the ranch. Meadow Creek Ranch LLC purchased the
property in the fall of 2016, and retained Claffey Ecological and Five Rivers Inc to review the
site and develop a creek restoration plan, which we completed in the spring and early summer of
2017. The property was formerly owned by Exxon Corporation and was leased to agricultural
operations and those operations continue today, with cows and hay production on the upper
ranch, and sheep and hay production on the lower ranch. The creek channel and adjacent
riparian communities have been heavily impacted by cattle and sheep grazing.
The client will continue ranching operations, but wishes to restore the creek channel to a natural
condition, improve aquatic and riparian habitats, and better manage the livestock and irrigation
practices. The ranch includes approximately 5 miles of Main Elk Creek, but this application is
only for the upstream 2.5 miles. We propose no work or limited work in a portion of this reach
to allow the channel to recover after grazing is restricted. A second phase of restoration work
would be proposed on the downstream reaches of Meadow Creek Ranch in the next year or two.
We are also submitting an application for a separate property, Main Elk Creek Ranch, that
adjoins this ranch upstream, and that work is similar.
We request authorization of this project under Regional General Permit 12. We plan to meet
with Colorado Parks and Wildlife on July 28 to review the project, and hope to have the letter
from CPW to you shortly thereafter. Five Rivers hopes to start the project in August of this year
and complete the work prior to October 1.

II. Project Area Description
Sections 1, 2, 14 and 15, Township 5 South, Range 91 West, of the 6th principal meridian,
Garfield County, Colorado
Upstream limit: 39.639961, -107.574360
Downstream: 39.609775, -107.582531
The project area is located at 5800 to 6000 feet above msl in Garfield County approximately 4
miles NW of Newcastle, Colorado. Elk Creek is a primary tributary of the Colorado River, and
drains the south side of the Flat Tops including Clinetop Mesa and Deep Creek Point (See quad
Copy attached). Between the higher elevations of the Flat tops and the project area, Main Elk
Creek flows through a steep narrow limestone gorge or canyon. The creek leaves the canyon
approximately 3 miles upstream of the project area. Elk Creek includes three channels, East Elk,
Main Elk and West Elk. Meadow Creek Ranch (MCR) lies along Main Elk Creek and Elk Creek
downstream of the confluence with West Elk Creek. The ranch includes approximately 5 miles
of stream corridor. The ranch is roughly split into the Upper and Lower Ranch using the Buford -
Newcastle Road as the dividing point. The project area segments of the ranch are adjacent to
BLM lands. Land use in the project area is primarily agricultural. The upstream end of the ranch
is bordered by Main Elk Creek Ranch, for which a separate permit application has been
submitted for the same type of restoration work. Upstream of Main Elk Ranch the land use
changes to small properties and newer homes along the creek channel up to the bridge for the
Clinetop Road.
The morphology of the project area is fairly narrow valley with steep hillslopes rising from the
valley floor. The channel is entrenched within the first floodplain terrace and multiple terraces
occupy the valley bottom. In many locations the valley floor is irrigated hay meadow and or
pasture, and sagebrush grasslands in areas not irrigated. In narrower sections of the valley
bottom is cottonwood riparian communities mixed with oakbrush. The hillslopes are either
oakbrush communities or pinyon juniper woodlands, interspersed with sagebrush.
Debris flow channels are present upstream and numerous debris flow fans. Wetlands are
restricted to riverine systems along the creek channel and are limited in width or not present
except for the downstream sections of the project area. In the upstream portions of the ranch, on
the east side of the creek, the steep hillsides are replaced by series of floodplain terraces that
have been cleared and irrigated.
Water quality appears to be good in this drainage, although we expect that late summer
temperatures are not conducive for trout due to irrigation diversions. The watershed above in the
canyon is limestone (CNHP Garfield County Report), so water chemistry could be very good for
trout fishery. Discussions with Ben Felt the CPW biologists indicates large numbers of brown
trout were sampled downstream of the Ware and Hinds irrigation diversion (downstream of this
property) during the fall of 2016. Trout Unlimited and the state have an agreement and permits
in place to construct a fish bypass through that diversion structure.

Meadow Creek Ranch
Channel Descriptions
We divided the project area into 5 stream reaches. The ranch has multiple channel types and
habitats, but all have been impacted by past and current agricultural activities. Trout habitat is
impacted by the changes in channel morphology but also by late summer irrigation diversions.
The combined effects of grazing, physical damage to stream banks as cows access the stream and
removal of riparian vegetation, and the subsequent bank erosion has impacted Main Elk Creek.
The bank erosion creates mid channel bars which over -widen the channel, and that combined
with the fact the channel can then no longer scour pools to create depth, along with mid to late
summer stream depletions from irrigation diversions degrades available trout habitat. We saw
very few trout during surveys in early April (low water) except Reach 5. Fine sediments
released from eroding banks and cows in the channel and on the bank cover the interstitial spaces
of the stream cobble substrate limiting macroinvertebrate habitat. Low flows in late summer
during irrigation decrease depth in the pools and increase temperatures. We have not been on
site in mid to late August yet, but have discussed stream flows with the ranch staff. We assume
temperature is limiting for trout populations in reaches 1-4 due to the combined effect of changes
in channel morphology and summer depletions.
The first reach, Reach 1 (Sheets 1 and 2), starting at the upstream property boundary is
approximately 3,300 feet in length and is a steep gradient reach, with large cobble to small
boulder substrate. The channel is well incised in a canyon like setting with a healthy and dense
cottonwood gallery forest along the shoreline except where steep eroded sections of the canyon
are present. It is entrenched below floodplain terraces. In the upper reaches gamble oak is the
woody shrub along the stream bank. Much of this reach is not affected directly by grazing
currently due to lack of grass, however stability has been affected by upstream bank erosion and
channel manipulations, as well as work on irrigation diversions within the reach. As such some
sections of the reach are over wide. The channel is filled with small boulders (20-24 inch
diameter) from past debris flows, and the channel does not have the capacity or flows to scour
pools or move this rock. There were several debris flows in and above this reach, including a
large one on the upstream property, Main Elk Creek Ranch. The reach would be a Rosgen B2
and B3 in some sections.
Sediment size for this reach is based on walking the channel for the length of work proposed.
A pebble count was not completed. The D50 is approximately 12 inches overall with larger
material in the 18-24 inch range in the pools. Width is typically good as erosion is not
substantial in this reach, but depth in pools is low as described above, less than 2 feet in summer
Width/Depth ratio has been increased in areas of irrigation diversions.
Reach 2 starts where Reach 1 ends in the open irrigated pastures, and is approximately 1,440
feet in length. The gradient lessens and the substrate is large cobble 8-12 inches (Sheet 3).
Grazing has impacted the stream and severe bank erosion with vertical, bare soil streambanks are
prevalent on the west side of the channel. This bank erosion has created numerous mid -channel
gravel bars and the stream is over -wide. A previous owner or manager installed a downstream
facing rock jetty in an attempt to control bank erosion, and the jetty has exacerbated the bank
erosion. Stream is a Rosgen B3 or 4. Cows are pastured in this reach with no limits on stream
access.

Main Elk Creek Aquatic Habitat Improvement Project
Meadow Creek Ranch
Substrate size was estimated by one pebble count across several habitat types. Mid channel bar
was D 50 of 4 inches, and stable riffle section was D 50 of about 12 inches. Generally pools and
riffles contained 6 to 12 inch cobble, and the mid channel bars were median of about 4-6 inch.
The substrate was covered with sediment expect in steeper riffles. The width depth ratio was
estimated at high — almost a 80 in the worst areas.
Reach 2 eroded banks and jetty
Reach 3 extends from the bridge downstream approximately 1,650 feet downstream (Sheet 4).
The channel is incised into the stream banks and old cobble dikes are present on the west side.
Limited channel meanders occur and the gradient is steeper than Reach 2. The stream would be a
Rosgen B4. The reach is within a mix of cottonwood forest with heavily grazed pastures.
Substrate size is large cobble to small boulders, and the gradient is steeper than Reach 2. It
appears this reach may have been straightened long ago, or at least contained with cobble berms.
This reach has a series of pools and riffles but the riffles no longer scour pools sufficiently, and
local bank erosion has created several overwide sections.
The substrate size was large in this reach with 12 to 16 inch material in pools and riffles and
larger material common. A pebble count across a pool revealed a D50 of about 8 inches. Width
depth ratio was not as poor as Reach 2 but still higher in pool sections than a stable reach as
depth was pool depth was low. Riffles and were about normal. Fine sediments covered most
low velocity areas.

Main Elk Creek Aquatic Habitat Improvement Project
Meadow Creek Ranch
Overwide section of Reach 3
Reach 4 is an unstable reach (Sheets 5 and 6) with intensive cattle use in the riparian areas, and
excess small cobble deposition. Streambanks are eroded and the meanders are extending. The
reach is a Rosgen C channel and is mostly a C5. A recent (not sure when) major flow event and
small cobble from the bank erosion within this reach and upstream has deposited large mid
channel bars of smaller cobble (2 to 4 in), and although there is a series of pools and riffles, the
next major flow event will alter morphology substantially. Unlike the upstream sections, the
channel will move the bedload present at moderate flows, and the lack of a stable riparian
community will unravel work completed. There is also an irrigation diversion for the Trout
Ditch which creates instability in one section. There is severe bank erosion in two sections of this
reach that help to contribute excess bedload and instability as the bank keeps eroding. Other
than repair of those banks, we propose to fence off grazing and let this reach recover on its own,
allowing the riparian and wetland woody shrubs to become established before proposing in
channel work. The reach is approximately 2,700 feet.
Substrate size in this reach was a D50 of 3-4 inches on many on the point bars and mid channel
bars and about 6 inches in the riffles and pools. The bars had excess material built up as
described above from recent depositional events. The width depth ratio was high in most
locations in excess of 50. Channels were very shallow and braided. In most locations the
bankfull width was in excess of 110 feet, and average bankfull depths were about 2 feet.
Reach 5 is a more stable reach that is starting to change due to cobble deposition and grazing
impacts. Cattle have access to this reach but have not impacted to the degree as above.
The reach has more and larger willow wetlands on point bars and the meanders are more stable
than Reach 4 (Shown on Sheets 7, 8 and 9). There is some development of mid channel bars and
bank erosion but not as severe as in Reach 4. Substrate size varies but is generally smaller in the
upstream section (4 to 8 inches), and larger in downstream sections (8-12 inches). Beavers are
present in this reach creating off channel dams in the wetlands, and one older eroded cross-
channel dam was present. Several deep holes created by scour points are present, and the dense
willow wetlands on the point bars and on stable banks provided for greater stability. This is the
first reach where we observed trout in good numbers during the April field work. This reach is a
Rosgen C4 and is approximately 3,800 feet.
5
Main Elk Creek Aquatic Habitat Improvement Project
Meadow Creek Ranch
Substrate size is D 50 of 8-12 inches in riffles and pools and 6-8 inches on point bars and mid
channel bars. Fine sediment covered cobbles in most sections with lower velocities. Width
depth ratio was better than Reach 4 but mid channel bars and some increased width is occurring.
Stable point bars with well vegetated wetlands help keep the reach stable. There were numerous
shallow water side channels that may provide juvenile refuge.
We found a USGS gage station at the upstream end of the property on the right descending bank.
The gage is no longer active and appears to have recorded from 1991 to 1998. The table below
shows peak flows from that time period with more than 1,300 cfs recorded in high water of 1997,
and two other high flows about 1,200 cfs in 1993 and 1995.

Main Elk Creek Aquatic Habitat Improvement Project
Meadow Creek Ranch
IV. Purpose and Need
The purpose and need of the project is to improve aquatic habitat in Main Elk Creek and stabilize
the stream channel on the first upstream 2.5 miles of creek on Meadow Creek Ranch. The creek
has been impacted by cattle grazing for many years, and the channel is not stable, lacks suitable
habitat components for viable fishery, and will not recover on its own even if all grazing is
removed. The channel has also been affected by the bank erosion and likely in -stream channel
work upstream and a massive bank erosion in 2011 on the upstream adjoining property.
Depositional reaches contain excess bedload deposited as mid channel bars, and that mid channel
bar then causes additional bank erosion. Reach 1 no longer has stream power to mobilize the
small boulders deposited by debris flows in the past and maintain adequate depth in pools.
The aquatic habitat is impacted by irrigation diversions during late summer and that combined
with the changes in stream morphology to shallow pools degrades aquatic habitat.
The project uses natural channel design and techniques Five Rivers and others have employed
throughout the west. Natural functioning riffles are used to control grade and maintain scour in
pools excavated in the correct locations. Pools provide adult habitat in winter and in summer
low flow and temperature refuge. The riffles and the constructed lateral bars help to narrow the
channel in locations to improve the width/depth ratio. Eroded stream banks are stabilized and
revegetated with several bio -engineering techniques. A series of log jams, similar to those
present, are created to provide scour points and pool depth, protect eroded banks, add large
woody debris and provide juvenile refuge habitat.
V. Proposed Work and Design
The proposed stream work s plan view is shown on Sheets 1-9, and the details (typical x -sections
and profiles) shown on the 3 additional Figures 1-3. Channel survey from SGM and a drone
over -flight aerial and topography have been completed and will be provided when it arrives.
That channel survey will be used by an engineering firm for the Garfield County "No Rise
Certificate", if a no rise is required by the floodplain administrator.
The excavation and fill quantities by stream station shown by station, and per habitat type are
included in Appendix B. The pools are shown in blue and the cubic yards for pools is all
excavation. Riffle, and lateral bars, bank toes and coir banks features are where there are
discharges of material below ordinary high water. That material is generally river cobble
excavated at the pool site but will include imported cobble from a upland harvest area on the
ranch in areas where cobble size was not large enough for riffles and bank toe protection.
In addition, some excavated cobble from Reach 1 will be used in downstream reaches. The log
jams are constructed with large boulders and those will be obtained from the rock jetty removed
in Reach 2. Appendix A provides cumulative totals for each habitat features.
The project will occur in 1.29 acres of creek channel in the 2.5 miles of creek, and approximately
1,413 cubic yards would be excavated over that length, and 1,605 cubic yards discharged into
ordinary high water. Approximately 174 cubic yards of large cobble (8-16 inches) excavated
from an upland area on the ranch would be imported into the river channel for bank stabilization
and riffle construction.
7
Main Elk Creek Aquatic Habitat Improvement Project
Meadow Creek Ranch
Five Rivers Inc has developed the proposed plans (attached) for this project, and Claffey
Ecological has assisted in the field work for design. Matt Weaver of Five Rivers has extensive
experience in cobble bed river restoration projects in Colorado, Montana, Wyoming and New
Mexico implementing those projects in the field. Mr. Weaver and/or Michael Claffey will be on
site during all phases of construction, and heavy equipment operators experienced with river
restoration will be completing the work.
All work proposed is below ordinary high water of Main Elk Creek, with the exception of few
spots where we would slope back eroded stream banks. There is no proposed discharge of dredge
or fill material in wetlands. We do propose to excavate willow clumps from dense willow
wetlands for bank restoration work as shown on the attached plans. We plan to harvest large
cobble for stream use from a location on an upper terrace that is not irrigated and is not wetland.
The cobble is on the surface or buried a few inches.
We do not provide a delineation of OHW as all work proposed is below ordinary high water, and
acreages and cubic yards discharged shown in Appendix B are all below ordinary high water of
the stream. In a few areas we slope back a vertical stream bank that would not be below ordinary
high water, and the cobble harvest area is in uplands. We also remove a cobble dike in Reach 3
which is above OHW. The entire project area is a series of riffle and pool complexes, albeit not
stable.
Overall design elements: The project will create stability and improve trout habitat by creating
a series of riffles, pools, and lateral bars in channel and stabilizing eroding stream banks with
bio -engineering techniques. Large rock structures are not proposed, and the in -stream work is
basically " actual manipulation of the active channel itself in an effort to improve fish habitat"
(from GP 12 Scope of Work). In this case, the design also attempts to narrow the channel where
it is overwide, but also to create better habitat for the late summer low flow conditions created by
irrigation withdraws.
Riffles are natural features that provide grade control in a stream, and help scour pools.
Five Rivers creates riffles at grade and excavates the pool downstream to create scour points.
The riffles are constructed at the appropriate length, width and grade to remain stable, however,
they do move — growing and eroding over time as the channel changes. Riffle are generally
constructed with the largest cobble available (D84), or imported 12-16 inch form the upland
harvest area. Riffles are riffle grade breaks that help maintain water surface elevation upstream
as well.
Pools create adult habitat for overwintering and general, but in this case also provide for refuge
areas during late summer low flows. Pools are excavated to 3 to 4 feet depths at summer flows.
The lateral bars help to reduce overall width in areas where the width -depth ration is off due to
mid channel bars and bank erosion. The proposed work of returning the channel to natural
configuration of pools, riffles and lateral bars, and the appropriate width will help maintain
stability by moving bedload through a reach and/or trapping it on lateral bars as a stable channel
would function. The riffles and lateral bars are low profile, developing a narrower channel at
low flow conditions but leaving plenty of channel capacity for high flow events.

Main Elk Creek Aquatic Habitat Improvement Project
Meadow Creek Ranch
The log jams (Figure 3) proposed are designed to reduce bank erosion and deflect high flows
from an eroding bank, with subsequent bank protection work completed just downstream of the
log jam. They also help create scour points in the channel creating deep pools providing refuge
for high water temperatures. In addition the log jams provide habitat for juvenile fish in the
denser areas where adults cannot access, and general large woody debris for aquatic food chain
support. We notice multiple natural log jams in the downstream reaches (4-5) that created
excellent scour pools. Weaver developed this specific design for salmon juvenile habitat in the
northwest, and they have been used successfully to establish large woody debris in channels.
Bank erosion is treated with two techniques — bank sloping/cobble toe and a coir lift. Bank
sloping (Figure 2) is used in areas with lower stream velocities, and involves simply excavating
back the vertical bank and building a toe of bank with 6 to 12 inch stream cobble embedded into
the channel for scour protection. Containerized willows and some transplants are installed above
the cobble toe, and the slope of the bank topsoiled, seeded and covered with erosion control
fabric. Coir banks (Figure 1) are soil encapsulated constructed with coir fabric (Bio D 90) and
supported with a large cobble substrate to prevent scour. The coir lifts are filled with cobble and
soil, seeded and under -planted with willows. The containerized willows are placed between the
cobble toe and the first coir lift.
Reach 1 (Sheets 1 and 2): As explained above this upstream reach is in a canyon like setting,
and gradient is steep (2 - 3 %). The reach has been affected by the 4 irrigation diversions
present, upstream bank erosion, bank erosion within the reach and numerous debris flows in the
past. The work proposed is the excavation of pools and then construction or enhancement of
existing riffles. In some locations mid channel bars have formed from excess bedload, and
riffles and lateral bars would be constructed with excavated material to narrow the channel.
Bank erosion is one location is stabilized with rock excavated for the pools. The excavation
work is limited in nature and primarily is rearrangement of existing substrate to increase pool
depth, and build riffles that will maintain scour. At Station 7+00 is USGS gage station.
Although this station is no longer active, we propose no work upstream or downstream for some
distance so long term readings are not affected if the gage is reactivated.
Trout habitat created in this reach is primarily adult although some juvenile habitat would be
available on the margins of lateral bars. Spawning habitat is not possible due to gradient and
substrate size. Pools are excavated to depths of 4-5 feet providing refuge for warm temperatures
during the late summer irrigation season, and overwintering habitat. The shade of the riparian
forest combined with the deeper pools will provide relief form high water temperatures in late
summer. In most locations excavated material from the pools is used to form riffles or lateral
bars nearby. In a few locations as shown on the plans where access is available, the excavated
material is hauled to an upland disposal area (storage) for later use downstream in streambank
restoration or riffle construction in reaches with smaller substrate (4).
Reach 2 (Sheet 3): This reach has been heavily impacted by cows. The adjacent meadows are
used for pasture rather than hay production and cows are kept in this area most of the spring.
Cows will be fenced from the stream creating a protected corridor of 50 feet on each side of the
channel. The cows have access the entire stream corridor, and degrade the stream banks both

physically by entering the stream, and by removing riparian vegetation. The bank erosion is
severe with vertical soil banks against stream flow releasing fine sediments downstream, and the
excess bedload from the original erosion created mid channel bars and bankfull widths of 100
feet with bankfull depths of 2 feet (W/D ratio of 50).
This is a relatively short reach but requires a good deal of work to stabilize streambanks and
restore the width depth ratio. The proposed work is a series of pools and riffles in the upper
sections, plus streambank restoration with bank sloping and willows plantings at station 36+00 to
38+00 as the slope has some rock protection at the toe. Cobble is added at the downstream end
this area at 37+50 to provide scour protection. In the downstream sections, the rock jetty is
removed, and streambanks are repaired using bank sloping/ rock and willow technique (Figure
2). The large rock is stockpiled for use in anchoring log jams downstream. The large gravel
bar/shallow water area on the left descending bank from 47+00 to 48+20 will be covered with
cobble and gravels, topsoiled, seeded and then covered with erosion control fabric to create a
riparian bench. This overwide and shallow area was created from the bank erosion forming a
mid channel bar and additional bank erosion. The streambank is eroded in this section but will be
sloped slightly to blend with the riparian bench. The existing mid channel bar is left in place and
shaped to form a lateral bar. The riffle or run on the right bank in this area is lowered
approximately 1 foot to create a more stable section and prevent lateral channel migration. The
work will effectively restore an appropriate stable channel width.
Adult habitat would be created with overwintering in the pools and refuge from high
temperatures. Some spawning habitat will be created naturally at pool tail -outs (where the pool
ends and starts a riffle, often containing the right depth and velocity for spawning) but will be
limited by substrate size. There is suitable size spawning gravels in the reach and they will be
randomly placed in suitable locations at pool tail -outs. Juvenile habitat will be created in the
shallow stream margins on lateral bars. The bank erosion and continued sediment delivery
downstream will cease.
Reach 3: (Sheet 4) Lateral bars are proposed in this reach in the upstream sections (Station
32+00 to 33+50) to narrow an over -wide section, but the main channel is left as long run and
riffle. An existing side channel on the left descending bank at station 52+25 is left open, this
channel only flows at high water and would not provide spawning habitat but could provide
juvenile refuge. The remainder of the reach is a series of excavated pools, lateral bars and riffles.
At Station 66+25, a log jam (Figure 3) is proposed at the downstream end of this reach to create
a scour point, and juvenile refuge habitat. A pool is excavated just downstream of the log jam,
and the scour from the log jam will maintain the pool depth. Between Station 59+00 and 61+50
a 3 foot high cobble dike had been constructed on the right descending bank to keep overbank
flows from reaching the hay meadow or pasture to the west. The cobble dike will be removed,
and the streambank seeded and planted with willows. The cobble will be used in riffle and
streambank repairs.
Adult habitat for overwintering and late summer high temperatures will be created in the pools,
and some spawning habitat in pool tail -outs. Juvenile refuge habitat will be created in the
shallow waters along the lateral bars and in the log jam. The removal of the cobble dike will not
10
Main Elk Creek Aquatic Habitat Improvement Project
Meadow Creek Ranch
create specific habitat but will allow for natural riverine functions such as flooding the adjacent
meadows during major flow events.
Reach 4: This reach is not stable. Other than major repair work at two eroded streambanks
(Sheets 5 and 6) no in channel work is proposed in this reach at this time. The reach is a C
channel, depositional reach and is heavily grazed by cows in the spring and early summer (up to
July 1). Gradient is lower than Reach 1-3 upstream and it appears that a major flow event (fairly
recent) deposited large amounts of bedload in this reach, and that bedload is primarily small
cobble. The proposal is to fence off from grazing and once cows are removed, the willows and
cottonwoods should colonize these bars, and either the reach would stabilize itself, or it
revegetate enough that we could review and propose riffle and pool in -channel work to enhance
fish habitat and additional stabilization work.
The bank erosion is severe in the two locations where work is proposed with 5 foot high vertical
banks. The Google Earth historic imagery below shows a 2005 aerial at the upstream bank
(Sheet 5). The image shows an October 2005 aerial image of the meander. The bank appears
stable through 2006 but in August 2011, it has eroded 70-75 feet west back to the blue line
(2011) which is basically the current bank line in 2017. We believe the event occurred during
2011 high flow as that event eroded a large bank upstream on Main Elk Creek Ranch, and was a
big water year on the western slope. The 75 feet is the apex or worse part of the erosion. This
provides a snapshot of the problems in this reach and on the ranch. The bank is approximately
300 feet long, and 5 vertical feet high. If we use 50 foot as the average bank loss for this bank,
than for more than 2,500 cubic yards of material (soil, cobble and gravels) washed downstream.
Some of the fine grained materials probably reached the Colorado, but the bedload or cobble and
gravel deposited downstream as mid -channel bars creating more bank erosion. Stabilizing the
stream banks on this ranch, and in this watershed in general, is critical for creating a stable
channel.

2005 GE imagery, Blue line is the 2011 bank line after erosion event.
Circles are GPS points on current bank
The proposed work for the bank protection is a soil encapsulated lift using coir fabric (Figure 1).
The coir fabric is BIO D90 from Rolanka and it is a heavy duty coconut fabric that with specs to
withstand high velocities, and biodegrades over a long period of time. We still find coir in banks
after 15 years, allowing for adequate time for the willows planted to become established, and
protect the bank with their root system. Weaver has extensive experience in stalling these bio-
engineered banks, and the coir is anchored into the upland edge in a trench, with willows planted
under the fabric as shown. Larger cobble is used for scour protection under the fabric. The bank
is built out in the channel to help narrow the channel a little in these sections, and the vertical
banks are sloped bank, topsoiled seeded and covered with erosion control fabric. Cobble will be
imported for the toe protection, and stabilization is enhanced by the construction of a log jam
upstream in the upstream bank on Sheet 5 (Station 75+50). The bank extends from
approximately 75+75 down to 78+30. The log jam works well at this location as the bank point
extends into the channel and the jam will deflect peak flows away from the bank and create a
scour point in the channel at the upstream end of the bank.

The other work in Reach 4 is the stabilization of the next downstream bank which is also
severely eroded. This is located at Station 88+50 to 90+00 on Sheet 6. A coir lift bank is
proposed in this section.
The lower bank shows more erosion than the upper with erosion between 2006 and 2011, and
then another event between 2011 and 2014. Since 2006, the right descending bank has moved
west over 115 feet, removing a fairly dense willow wetland in the process.

6-2014 imagery, which same today.
The channel moved west 40 plus feet between 2011 and 2014, and has about 60 feet more to go
before it hits the County Road. The erosion between 2011 and 2014 was likely caused by a
downed conifer on the bank visible on the 2011 imagery.
Reach 5: As described above this reach has been impacted by cattle and is now experiencing
excess cobble deposition yet still remains fairly stable due to well vegetated point bars. The
cattle use this area but not as extensively as upstream. Work in this reach will probably create
the best fishery in the project area.
Sheet 7 shows a series of riffles, pool and lateral bar work from Station 100+00 down to 107+00.
At about Station 107+50 on the left descending bank is severely eroded stream bank. The bank
extends approximately 220 feet downstream, and is about 5 feet high. For this work, the bank is
not sloped back as some riparian woody species are still present at top of bank and removal of
material form this reach would be difficult. Large cobble is placed at the toe of bank and the
bank line planted with whole live willow at 7 foot spacing and the nursery willows at 1 foot
spacing. The whole live willows are harvest form the adjacent willow wetland, excavation only,
and minimizing disturbances. In addition, four small log jams are constructed along the bank
line as shown. The jams will deflect high flows from the bank allowing the willows to grow in
and stabilize the bank.
Sheet 8 depicts two log jams and scour pools proposed in the upper section on the right
descending bank with lateral bar on the left (station 113+00 to 114+00). The channel is
overwide in this section and in addition to juvenile habitat, the log jams will prevent lateral
channel migration to the west. Cobble is placed on an eroded bank section. A series of
riffle/pool and lateral bars is created downstream between 116+0 and 122+00 while leaving
several long riffles and runs in place as they appear stable.
15
Main Elk Creek Aquatic Habitat Improvement Project
Meadow Creek Ranch
At Station 123+00, a rip -rapped bank on the right descending bank has eroded exposing fiber
optic cable for short distance. The riprap created a deep scour hole (likely) at this location and
adjacent shrubs and trees provide good shading. We propose no work to stabilize the bank as the
fiber optic cable should to be addressed by whoever is responsible for maintenance.
Sheet 9 includes a series of pools, riffles and lateral bars from Station 127+50 down to about
134+50 in a meander sequence with good riparian cover on the banks. At about station 134+50
is an eroded stream bank on left descending bank, and will be stabilized using the cobble at the
toe, whole live willows and nursery willows. Again the bank is not sloped back as some riparian
shrubs are on top of bank and removing material from this reach would be difficult. Work on
two pools and lateral bars is completed to end of project area at Station 137+25.
VI. Terms and General Conditions
Item 5 of information required includes pre -project photos at fixed GPS points depicting the
physical setting to be compared with post project photos. These project photos will be submitted
with GPs location, bearing and a general description prior to any work. Photos will be submitted
from the same points and bearing with each monitoring report. A representative selection of
riffles, pools and lateral bar work areas will be selected within each reach, and most of the bank
restoration sites.
The project has or will comply with the 30 general conditions of RGP 12. Endangered Species
Act and Section 106 are discussed below as well as sediment control during construction.
ESA: I did a search on the US Fish and Wildlife Services' web site for listed species and their
habitat in Garfield County and then specifically the project area. The project area is listed as
potential habitat for Ute Ladies' Tresses (Spiranthes diluvialis), and further checking with
Ecological Services Grand Junction office (Dara Taylor, personal communication June 2017)
revealed the project area was in the Section 7 survey area for Spiranthes. Ms. Taylor indicated I
could provide a rationale for why surveys for this plant should not be required, and they would
consider that rationale. On July 3, 2017 I submitted a letter report to Ms. Anne Timberman of
the Ecological Service office providing a rationale of why surveys were not required for this
species and copied Mr. Travis Morse of the Western Colorado Regulatory. The letter briefly
described the project area and the restoration project, and explained that no proposed work
would occur in possible habitat for this species. The FWS responded on July 7 by email from
Dara Taylor that Spiranthes surveys would not be required, and they copied Mr. Morse on that
email (copy enclosed).
No other listed or candidate species occur in the project area or whose habitat would be affected
by the project.
Section 106 of the National Historic Preservation Act: It does appear that any cultural
resource sites would be affected by the project. To facilitate review for the Corps we have
requested a Class 1 Files Search through Metcalf Archaeology of the river corridor in the project
area (including Main Elk Creek Ranch upstream). That report is included in Appendix B.
16
Main Elk Creek Aquatic Habitat Improvement Project
Meadow Creek Ranch
The project area is an active fluvial environment and little if any cultural resources could last
within the active channel where we propose work. There is an old piece of farm equipment in a
pasture in Reach 4 near the upstream eroded bank, and lumber remains nearby. Both are not in
"waters of the US" and neither would be disturbed during construction. Based on Appendix C of
33 CFR 325 neither would be within the Corps "permit area" as they do meet definition g (1) ii
and iii.
Sediment Control: Work in the river will generate sediment which is unavoidable.
The contractors will employ techniques to reduce sediment plumes, although work of this nature
has occurred in many miles of stream son the western slope with little if any measurable
sediment impacts downstream. Wheeled vehicles such as trucks and front end loaders will not
work in the river. It is expected only one tracked excavator will be working in the channel.
If sediment plume becomes excessive, more than the creek flow can dissipate in several hundred
feet, the work will stop for a duration of time to allow for absorption of the sediment. In the past
that has been anywhere from 10 minutes to 1/2 hour. We do not expect major problems as there
are very few clays or fine particle soils in the area, and the substrate is small to large cobble.
In addition, irrigation diversions that the ranch controls will be kept to a minimum or cease while
the river work is underway to keep flows high. If necessary the irrigators will irrigate in the
evening and night when river work ceases.
Bank restoration work by its nature can generate sediment as often the cobble and gravels have
been stripped away by the erosion events, and only soil is being worked. As bank work is
completed, small cobble coffer dams can be placed at the upstream end to deflect flows away
from the bank while the major excavation work is underway. Those coffer dams are then moved
downstream as needed, and incorporated into the next feature when the bank work is completed.
Monitoring Reports: A construction report will be submitted in the fall of 2017 after the
project is complete including site photographs of construction techniques, and the same photo
points at GPS locations as the pre -project photos with a brief description of the site conditions.
A monitoring report will be submitted after high water in the first year after construction (2018)
to include all photo points submitted with pre -project photos, and include a brief description of
site depicted. A second monitoring report would be submitted after high water 3 years (2020)
after construction using the same photo points and a description.

VII Conclusion
The proposed project will improve aquatic habitats in this reach of Main Elk Creek. In addition,
the stream will be stabilized with the proposed bank restoration and developing stable riffle, pool
and lateral bars, and having the channel width back to an appropriate width, and width/depth
ratio. Long term viability of the aquatic environment and the riparian communities will be
greatly enhanced by the removal of grazing from the riverine environment. The riparian and
wetland habitats in Reaches 3, 4 and 5 will restore substantially on their own in few years, and
this restoration will help improve not only the aquatic environment but any ecosystem services
these habitats provide. Rough measurements reveal the woody riparian habitats in these three
reaches that will restore gradually to native, undisturbed riparian corridor is about 55 acres.
Water tanks will be developed during the project implementation to water cattle to ensure the
cattle stay out of the creek channel and the large riparian habitats. Cattle were moved to the high
country after July 1 and return in the fall. Fencing will be constructed after each reach of the
project is completed, and before cattle are in the adjacent pastures.
All in all about 2.5 miles of riverine corridor will be restored to a natural functioning system.
If the TU project on the Ware and Hines Ditch diversion is implemented to allow for fish
passage, the trout from the Colorado could move into these habitats for spawning, and a viable
natural population established.

Dear Ms. Timberman:
I am representing two clients on river restoration projects on Main Elk Creek in Garfield County,
and we will be applying for a Regional General Permit 12 from the Corps in the near future.
These are adjoining properties, and cover in total about 6 miles of the creek. The upstream
property contains about 1 mile of creek corridor and is called Main Elk Creek Ranch and the
downstream property is about 5 miles of creek corridor and is known as Meadow Creek Ranch.
I spoke to you briefly about this project, and in more detail with Dara Taylor of your office.
Dara responded by email after reviewing quad location map I provided that the projects were in
the Section 7 consultation area for Ute Ladies'Tresses (Spiranthes diluvialis), and that we would
need to provide a rationale for why habitat is not present to avoid survey requirements. I hope to
provide that rationale in this letter report.
Elk Creek is a tributary to the Colorado and drains the southern portion of the Flat Tops.
The stream is generally high to moderate gradient, with small to large cobble substrate and a
bankfull width of about 30-45 feet. The stream and riparian habitats are heavily impacted by
grazing and stream flows are affected by irrigation diversions in the late summer. Highly eroded
stream banks, mid channel bars and over wide sections of channel are common. Water quality
appears to be good. The restoration project has been designed by Five Rivers, Inc and includes
creation of a series of pools, riffles and lateral bars, as wells as restoring eroded stream banks to
re-establish a natural self sustaining channel and improve aquatic habitats. Plans include
extensive riparian fencing to keep cows and sheep out of the riparian habitats, and better
management of water use. We have 4000 native willows shrubs growing in a native plant nursery
to be used in bank restoration.
Spiranthes diluvialis (SPDI) occurs in moist meadows associated with perennial streams,
floodplains, and oxbows, seasonally flooded river terraces, sub -irrigated or spring fed abandoned
stream channel. It has also been found in irrigated meadows, excavated gravel pits, roadside
barrow pits, reservoirs, irrigation ditches, berms, and other human modified wetlands (FWS
ECOS website). In Colorado, SPDI was primarily found on the front range and along the Yampa
River in the northwest corner in Moffat County, but more recently found in the Roaring Fork
970-640-3783
mclaffey@acsol.net
valley in Garfield County. Colorado Natural Heritage Program (CNHP) lists the habitat as along
streams and open areas in cottonwoods, moist meadows on floodplains in the vicinity of
abandoned stream channels and meanders where vegetation is not too dense or overgrown
(CNHP website). Fertig et al (2005 — Rangewide Status Review of Ute Ladies' Tresses) report
the habitat for SPDI as the same conditions but also noted that most populations occur in habitats
that were not overly dense or heavily grazed. The main elements of SPDI habitats are they occur
in wetlands, either natural or man-made. The associated plants found with SPDI are wetland
species.
For these two river restoration projects, the work will occur in the active channel of the river, or
on severely eroded stream banks, and no work is proposed in wetlands. Work is proposed in the
upper 3 miles of the stream. The downstream sections of Meadow Creek Ranch would be
completed later. The irrigated meadows near Main Elk Creek are very dry, produce one hay crop
in spring, and do not contain wetlands or irrigation return flow wetlands. The surrounding
habitats are oakbrush and pinyon juniper. Oakbrush is often a riparian plant in some locations.
The soils are well drained, and the main species in the irrigated meadows are smooth brome,
orchard grass and wheatgrass. There are not any abandoned stream channels or oxbows in the
project area. The upstream property (main Elk Creek Ranch) has a large wetland area fed by
irrigation water but the habitat is dense willow cover and no work is planned in or near these
habitats. There not any sub -irrigated meadows or springs where we plan to work. The irrigated
meadows are on higher terraces and based on limited irrigation water in mid to late summer, and
the arid conditions, sub -irrigated wetlands simply do not occur.
Access points are dry meadows at eroded banks (we repair the bank as we leave that reach of
stream), existing ranch roads, and drier upland areas near the creek. This is a restoration project,
and any vegetated wetlands or riparian habitats are generally avoided as it is difficult to establish
this type of community during restoration, and we are also under review by the Corps for
wetland impacts. A track hoe enters the creek and typically stays within the active channel.
Pools are excavated and the material excavated used to create riffles to maintain scour in the
pools. Lateral gravel bars are created with the excavated material in reaches that are over -wide
due to bank erosion to also maintain scour in the pools and runs. The bar is formed in the open
water of the overwide section to narrow the channel and maintain scour. Heavy equipment will
not be driving through wetlands to access the channel, and there are not any out of channel
disturbances in wetlands or riparian habitats proposed. The heavy equipment operators
specialize in this type of work, and are well aware of the restrictions and a project manager is on
site at all times.
The downstream sections of Meadow Creek Ranch include a more meandering stream channel
with dense willow wetlands (Salix exigua) in riverine conditions. There locations in this
downstream reach were mid channel bars and erosion as has created back water areas, and low
gradient side channels across point bars. These areas are left as is because they create excellent
refuge habitat for juvenile and YOY trout, improve diversity of the aquatic ecosystem, and also
because the Corps and CPW (Corps solicits CPW comments on all GP 12 applications) would
not generally approve impacts in these types of habitats. There is also not a need to work in these
areas and the heavy equipment work is costly.
2
There is one area where we currently plan to harvest some whole live willows clumps to use in
restoration of the eroded stream bank in this reach. This is a dense coyote willow stand (Salix
exigua) with closed canopy of willows and is not SPDI habitat due to canopy closure.
Approximately 30 clumps would be removed for use in stabilizing the stream bank.
We do not believe that habitat for this species is located in the areas we intend to work for this
restoration project. There are not any permanent fills or removal of vegetated habitats that would
affect SPDI as work occurs in the live stream or on eroded stream banks. I will provide a disc
with the plans or send them electronically if google drive would work.
We request that survey requirements for SPDI are not required for these two projects, and that
your office either notifies me, or the Corp of Engineers, Grand Junction office (Mr. Travis
Morse) that surveys are not required.
Thank you for your time and consideration.
Sincerely,

Re: Claffey Ecological Consulting, Inc.: Cultural Resources Class I Files Search for the USACE Elk Creek
Restoration Project, Garfield County, Colorado
Dear Mr. Claffey,
Metcalf Archaeological Consultants, Inc., at the request of Claffey Ecological Consulting, Inc., is providing
the results of a Class !files search and literature review for the proposed Elk Creek Restoration Project in
Garfield County, Colorado (Maps 1-4, attached). The purpose of this study is to provide information to
Claffey Ecological Consulting, Inc. and its client with information on known cultural resources in the
project area, as well as a summary of cultural resource inventory that has already occurred. The
majority of this project is located on private lands; however a tiny part of the corridor extends onto
lands administered by the Bureau of Land Management, Grand Junction Field Office in Section 2. The
information in this report will be used for future project planning. It is our understanding that this
project will require federal agency oversight (USACE, and possibly BLM) for permitting when it proceeds.
The proposed 400 foot wide corridor for restoration along Elk Creek is shown in the attached Maps 1
and 2, prepared by us from kmz files provided by you, showing the location of the proposed project area
relative to the footprint of previous cultural resource inventories conducted. A second set of maps,
Maps 3 and 4, shows the locations of previously recorded cultural resources near the project footprint.
Those resources within the 400 foot corridor are shown in red. These maps are included in agency
copies of this report only. They are for official use only and not for public distribution. Disclosure of
site locations is prohibited by federal law (43CFR7.18).
FILES SEARCH RESULTS
A total of eight previous cultural resource inventories have been conducted within the legal sections
containing the creek restoration corridor (see included table and Map 1). A large portion of the corridor
was covered by a previous block inventory (OAHP #GF.R.R4) in 1978 by the UNC Office of Public
Archaeology. However, in our experience, reviewing federal agencies, including USACE, require that
surveys older than about 15 years be completely re -done. The other previous inventories in the project
area only intersect small portions of the corridor. Therefore, we anticipate that a 100% inventory of the
creek restoration corridor will be required for project permitting.

Two previously recorded cultural resources (5GF316 and 5GF401) are located within the 400 foot creek
restoration corridor (Maps 3 and 4). Neither of these sites have official recommendations for eligibility
to the National Register of Historic Places (NRHP). At a minimum, these sites will need to be re -visited
and evaluated for eligibility to the NRHP; it is also likely that new site forms will need to be completed
for them.
To arrive at these recommendations, we requested and received GIS site and survey data from the
Office of Archaeology and Historic Preservation (OAHP) on July 11, 2017. We also queried OAHP's online
Compass database for information specific to previous inventories and previously recorded cultural
resources.
Previous inventories located in the legal sections containing the restoration project are presented
below. Those that cover some portion of the project corridor are in bold

The previously recorded resources include four prehistoric open camps, one prehistoric isolated find,
one historic agricultural complex, one historic log barn, one historic habitation, and one historic ditch.
In addition, there are two paleontological localities in the project area. All of the resources are outside
of the planned creek restoration area, except for site 5GF316 and 5GF401, which are within the 400 foot
wide corridor. Site 5GF316 is a prehistoric open camp that is officially listed as "needs data"; it is
located 92 feet from the center of the creek. This recommendation indicates that an NRHP
recommendation of eligible or not eligible could not be confidently made by the surface expression of
the site alone. "Needs Data" sites often require limited subsurface testing to prove whether or not they
retain potential for additional data and are NRHP eligible. Site 5GF401 has very little information on
record in OAHP's database, but appears to be a historic log structure. It is located 147 feet from the
center of the creek. It does not currently have an NRHP recommendation listed in the records.

Claffey Ecological Elk Creek Restoration Class I
DISCUSSION AND EXPECTATIONS
Metcalf, using results of the OAHP records files search, concludes that there is good potential for
encountering cultural resources within the proposed Elk Creek restoration project area. Previous work
indicates a moderately high site density in the area, and the margins of creeks have always been a
favorable location for habitation in both prehistoric and historic times.
Although one large block inventory has occurred within the project corridor and covers a large portion
of the restoration area, it is too old (1978) to be considered adequate by federal agencies for cultural
resource permitting. The other previous inventory within the area of potential affect only intersects the
corridor in a small area, so it does not provide substantial coverage.
RECOMMENDATIONS
Because the proposed restoration area has not been systematically surveyed within the last 39 years,
Metcalf recommends planning for a Class III inventory of the entire 400 foot wide corridor if the projects
require it for permitting; or if federal funding is involved and Section 106 review is required.
Furthermore, based on previous work the area appears to have prehistoric and historic site potential.
Both of the known archaeological sites will need to be revisited and evaluated for NRHP eligibility. If an
NRHP recommendation cannot be made from the surface expression of the site alone, limited testing
might be needed to determine whether or not the sites retain research potential.
For scheduling purposes, a Class III inventory of a project this size can be completed fairly quickly, start -
to -end probably over the course of a month including reporting. Limited site testing to determine NRHP
eligibility can be done quickly, usually within a day at each site. The consultant's report then is
reviewed by the lead agency, a process that typically takes 2-4 weeks and depends entirely on the
agency's staff availability and internal agency priorities. If sites are found that are known to be, or
recommended to be, eligible for the National Register, the agency is usually obligated to consult with
the OAHP on findings and recommendations, a review process that can take up to an additional 30 days.
If there is need to conduct mitigative work—if the project is found to have an adverse effect on an
eligible site, and the project design cannot be changed to avoid the site—a plan for that work is
prepared, reviewed, and then accepted by the lead agency and OAHP, after which it can implemented.
This can take several weeks or months. All of this usually needs to happen before any restoration work
is allowed to proceed. For projects that anticipate mitigation, Metcalf recommends planning to begin
the Class III inventory process as early in project planning as possible. Inventory work can begin as soon
as the ground is 80% free from snow. For projects that do not end up requiring some form of mitigation,
a three month time frame from initiation of cultural resource work to agency acceptance of a final
report of that work, is reasonable.

The files search indicated the presence of two paleontological localities in addition to the cultural
resources. The lead federal agency may require that a paleontology survey of the restoration area is
conducted in addition to cultural resource inventory, if they judge that the area has potential for these
kinds of resources. Metcalf does not have a paleontologist on staff, but we do routinely sub -contract
with several paleontology consultants in northwest Colorado. We would be happy to provide this
service directly if needed for this project, or provide references to Claffey Ecological.
If you have any questions, or if we can be of further assistance, please do not hesitate to call.

Note: The existing streambed consists of gravel/cobble deposited over valley fill and intermittent sand/clay layers. The valley fill substrate consits of
alternating lenses of sand, gravel and 0.5 to 2' sub -angular limestone and sandstone fragments in a fine-grained clay/silt matrix.

SCOUR POOL DEVELOPEMENT
DOWNSTREAM OF LOG JAM
Description: Log jam consists of 3 to 5 large cottowood logs cabled
to 4 to 5' boulders. The cable is secured to boulders using cabled
inserted into 18" deep drilled holes and cemented using heavy duty
construction epoxy. The logs will be selected from numerous off -
channel, fallen, dead cottonwoods on site. It is predicted that a
scour pool will form below the log jam. The primary current
deflector log is placed at a 25 to 35° angle off the bank in an
upstream direction. The log projects into the channel approximately
0.2 X Channel Width. At this site the primary current deflector log
would project 12' into channel. This alignment deflects flow away
from the downstream eroding bank.
