The project develops the flows of Cimarron Creek, a <br />tributary of the Gunnison River, for irrigation and for benefits to <br />sports fishing and recreation. A full and supplemental supply of <br />irrigation water is available for 5180 acres of land. Recreation <br />opportunities and important fishery benefits are provided at Silver <br />Jack Reservoi r. <br /> <br />Storage regulation is provided by Silver Jack Dam and Reservoir, <br />constructed on Cimarron Creek. Project water is rel eased from the <br />reservoir to Cimarron Creek. The releases, along with usable <br />natural flows, are diverted from the creek into the Cimarron Canal <br />at a point approximately 2.5 miles below the dam and conveyed 23 <br />miles to the vicinity of the project lands. The Cimarron Canal is a <br />privately owned and operated facility and is not a component of the <br />Bostwick Park Project. Some water is released from the canal and <br />used on lands in the Cimarron area. Most of the water is conveyed <br />to the canal termi nus at Cerro Summi t and then deli vered to the <br />Hairpin and Vernal Mesa Ditches. The Bostwick Lateral diverts water <br />from the Vernal Mesa Ditch and conveys it across Bostwick Park <br />through an 18-inch siphon to lands above the West Vernal Mesa <br />Lateral. <br /> <br />Principal project features are described as follows: <br /> <br />Silver Jack Dam and Reservoir. Silver Jack Dam is located on <br />Cimarron Creek about 20 miles above its junction with the Gunnison <br />River. The ro11ed-earthfi11 dam has a structural height of 173 ft. <br />Its crest is 1050 ft long and 30 ft wide. Total volume is 1,278,140 <br />cubic yards of material. The outlet works to Cimarron Creek in the <br />right abutment has a capacity of 280 cfs with the reservoir at the <br />normal water surface elevation of 8926.0 ft and a capacity of 160 <br />cfs at the minimum water surface elevation of 8840.0 ft. The <br />spillway on the right abutment is an uncontrolled ogee section with <br /> <br />B-14 <br /> <br />[J c., \(\.,-:7641 <br />\,~.i \J '..J : J ~ <br />
