Water Resources Consulting October 9, 2017 Jody Daniels 176 GH Daniels Blvd. Gypsum, Colorado 81637 Re: Quicksilver Court Subdivision Garfield County, Colorado, revised Job No. 720.1 1565 Gilpin Street Denver, Colorado 80218 (303) 321-8335 (303) 321-8346 (FAX) Dear Jody, The purpose of this letter Report is to address the County's concern about the adequacy of the production of Daniels Well No. 2 for the Quicksilver Subdivision (Permit No. 67565-F). The Water Supply Report, submitted in support of the Quicksilver Subdivision on October 2, 2008, stated that it is anticipated that Daniels Well No. 2 will serve Lots 6 and 7 (a total of four units). That Report also indicated that the maximum average daily demand per well is anticipated to be 2,448 gallons, or an average of 1.70 gallons per minute (gpm), based on the maximum annual demand of 2.74 af/yr per well. As discussed in our October 2008 Report, Daniels Well No. 2 was drilled and completed on March 10, 1999 to a depth of 223 feet. The static water level in the well prior to the test was approximately 119 feet below top of well casing. A pump test was conducted on Daniels Well No. 2 for approximately three hours on February 13, 2008, originally at a rate of 4.2 gpm for 2 hours, then after recovery, at an increased rate of 9 gpm for an additional hour with a full recovery period of 18 -hours. The original 2 -hour test, and the 1 -hour and 18 -hour recovery test are presented in graphical form attached to this letter as drawdown vs time, as Figures 1 and 2, respectively. The drawdown data from both tests, and the recovery data were interpreted to determine the average transmissivity of the aquifer of 53 gpd/ft. This value was used, as discussed in our October 2008 Report, to support the opinion that the well was capable of a sustained yield of at least 1.7 gpm and 2.74 of/yr. For purposes of supporting the determination of whether Daniels Well No. 2 is adequate to support the proposed demand of 1.7 gpm, it is useful to focus on the graph of the 2 - hour test results shown on Figure 1. That graph indicates that the drawdown of the Quicksilver Court October 9, 2017 Page 2 water level in the well at the end of the 2 -hour test at a pumping rate of 4.2 gpm was about 23 feet. In addition to using the time -drawdown graph for calculating aquifer parameters, it can also provide a useful means of predicting future drawdowns (see Groundwater and Wells 2nd Edition by Fletcher Driscoll, 1986). This can be accomplished by extending the drawdown line on that graph an additional 2 hours, which then indicates the drawdown of the water level in the well that would have occurred at 4 hours into the test at that same pumping rate (4.2 gpm), or a total drawdown of 23.6 feet (see Figure 1). This is the drawdown that would have occurred had the well been pumped for 4 hours at 4.2 gpm. Considering that the available drawdown in the well was about 104 feet at the beginning of the test indicates that the well is capable of producing in excess of the required average annual yield of 1.70 gpm (2.74 of/yr) needed for the water supply to meet the development's demands. In my opinion, this analysis indicates that Daniels Well No. 2 is adequate to meet the Quicksilver Court Subdivision's demands and satisfies the County's water supply testing requirements as cited in Section 4-203 (M)(1)(b)(5)(a) of the Land Use Development Code for water supply from ground water sources..

I have made a site visit to this location and reviewed the digital application. I have some concerns with the existing water supply for the subdivision and they are as follow: 1. Lot 7 well supplies the water for the fire suppression water in the pond. With adding two homes to the well, is the usage of water for the homes going to allow for the pond to be refilled when and if needed along with maintaining the full status of the required water supply in the original subdivision plat? 2. On my site visit on Monday, the pond was close to full but the vegetation (cattail's and other growth) in the pond may hinder the drafting of the water from the pond through the intake of the suction pipe. The pond appears to need some cleaning and maintenance. The owners should make contact with me so we can agree on a pond maintenance schedule. I have no other requirements or concerns with the proposed ADU's at this location. Mr. Daniels has responded to my concerns with a plan to reduce vegetation in the pond and has provided me with information on the water wells that supply the water for filling the Fire Suppression Pond. The information provided to me from Mr. Daniels has addressed my concerns to the addition of ADU's. No further comments or concerns for this project. Colorado River Fire Rescue Thank you for allowing me to review this referral and please feel free to contact me with any questions or concerns. . Thank You, Orrin D. Moon, Division Chief/Fire Marshal
