<br />" <br /> <br />Water Project Construction Loan Program. Project Data Date <br /> <br />.. <br /> <br />Borrower: Young Creek Reservoir Company <br /> <br />Project Name: Young Creek Res. # 1-2 <br /> <br />Drainage Basin: Gunnison <br /> <br />Total Project Cost: 5217,125 <br /> <br />Type of Borrower: Agricultural <br /> <br />CWCB STTFPBA Fund Loan: 5195,400 <br /> <br />County: Delta <br /> <br />Project Type: Reservoir Rehabilitation <br /> <br />Water Source: Young Creek <br /> <br />Funding Sources: CWCB. Suriace Creek Bank <br />Aver. Delivery: 782 acre-feet (decreed capacity) <br /> <br />Interest Rate: 2.50% <br /> <br />T enn: 30 years <br /> <br />YCRC provides irrigation water to a 400-aO"e service area in Delta County near the Town of <br />Cedaredge. The YCRC owns & operates two reservoirs, the Reservoir #1-2 (a combined <br />reservoir), and Reservoir #3. both located on Grand Mesa. Reservoir #1-2 has a decreed .capacity <br />of 782 acre feet, and is over 100 years old. The existing dam Is a Class 2 dam, with a length of 505 <br />feet, height of 46 feet, crest width of 15 feet, and spillway width of 25 feet. There is a history of <br />seepage problems, and a recurring incidence of sinkholes In the area immediately upstream of the <br />dam, along the left abutment This has necessitated temporary sinkhole repairs on several <br />occasions, as well as Instituting a monItoring program to assess the performance of the dam. In <br />2001. a geotechnical investigation was completed and paired pIezometers were placed within the <br />embankment structure. SInce the Installation the reservoir has not filled due to the drought, and It <br />has not been possible to evaluate dam performance over the past two years. Several time <br />extensIons for performance reporting have been granted by the SEO. YCRC wants to make the <br />most crttlcal repairs now to avoid potential loss of function of the reservoir and possible restriction. <br />Currently, the dam is approved for conditional full storage, requiring continued efforts to address left <br />abutment seepage. The proposed liner project will address the Immediate sInkhole problem by <br />Installing a 80 mil HOPE (High Density Polyethylene) liner over an area about 200 feet long by 140 <br />feet wide, covering a total of 3100 sq. yards, in the area of sinkhole occurrence. Future monitoring <br />of the dam performance after the initial repair will allow YCRC to determine If additional repairs are <br />necessary. <br /> <br /> <br />".". <br />... <br />"i;:. <br /> <br /> <br />. <br /> <br />Location Map <br />
