.\ Beaver Creek Reservoir Company Agenda Item 14a November g, 2004 Page2of4 . requires replacement. The new gate valve will be manually operated which will improve reliability and reduce costs. Feasibility Study James Briscoe, Briscoe & Stanway, P. C. of Hotchkiss, Colorado, has completed the feasibility study in accordance with CWCB guidelines. The study includes engineering and cost estimates prepared by James Johnson of Golder Associates, Inc. The design and construction plans will be reviewed by Jim Norfleet, Dam Safety, SEO Division 4. Mr. Norfleet indicated that he supports the concept of the proposed improvements, but has not reviewed the plans. The Beaver Reservoir ComDanv The Company is located in Paonia, Colorado, 30 miles east of Delta. The Company was incorporated in the State of Colorado in 1956 and is a Non-Profit Corporation Water Company in existing status. The Company consists of three shareholders and a total of 1600 shares: Minnesota Canal and Reservoir Company (900 shares), Tumer Ditch Company (400 shares), and the Lone Cabin Ditch and Reservoir Company (300 shares). The Company has the power to "levy assessments", "terminate delivery of water to", "commence a civil action against" shareholders that fail to pay assessments, and the option to sell delinquent stock to pay back default assessments. The Reservoir is the only water supply facility owned and operated by the Company, Water RiQhts The water rights for Beaver Reservoir water are held for the benefit of the Company shareholders. The Company has a 1,620 acre-feet storage right with a 1954 adjudication date. The reservoir receives flows from the East Fork of Minnesota Creek, a tributary to the North Fork of the Gunnison River. Minnesota Canal and Reservoir Co. and Turner Ditch receive flows from reservoir releases and Lone Cabin Ditch and Reservoir Company receives its proportionate share through an exchange diversion at a higher elevation from the Middle Fork Minnesota Creek. The reservoir is typically filled and drained once a year. Since the 1995 liner project, the reservoir has been filled to capacity every year. . Project DescriDtion The purpose for the Project is to stabilize the lower edge of the liner that was installed in 1995 and to prevent undermining and erosion beneath the liner. The Project also consists of replacement of the malfunctioning and unreliable hydraulic valve and gate on the intake of the outlet structure. The Company has considered different materials and sources of the materials in the evaluation process. The Engineers have indicated that the on-site material has a high probability of meeting the specification required for the liner protection. The Company has also evaluated 3 options to improve the intake of the outlet structure. These include repair of the old hydraulic gate, removal and replacement of the existing structure, and modification of the existing structure with a new gate. The selected alternative includes the construction of a new structure around and above the existing . structure to accommodate a manually operated gate with a new stem and air vent. This will require raising the height of the intake structure by 10-feet and installing a 24-inch gate and stem. This
