Show Starvation Reservoir now fitting With the closing of the bulkhead bulk-head gate on the outlet works of Starvation Dam, storage of water began in the first reservoir reser-voir of the Bonneville Unit- of the Central Utah Project. Water Wa-ter storage in the reservoir is to be used to supplement the inadequate irrigation supplies in the vicinity of Duchesne and to replace some water that will be diverted for use in the rapidly ra-pidly expanding Wasatch Front area. The Bonneville Unit is being sponsored by the Central Utah Water Conservancy District. Dist-rict. Starvation Reservoir is on Strawberry River about 3 miles upstream from Duchesne. However How-ever most of the storage water will come from Duchesne River. Water diverted from that river by the previously completed Knight Diversion Dam flows through a concrete pipeline and the finished mile-long Starvation Star-vation Tunnel to the reservoir. When full, the reservoir will store over 167,000 acre-feet of water and will have a surface area of 3,310 acres. The 155-foot-high Starvation Dam has been about 2'i years in the making. Clearing operations opera-tions at the damsite were begun be-gun in March 1967, but con- . struction was suspended during dur-ing the two winter seasons. The dam consists of 4,600,-000 4,600,-000 cubic yards of fill material weighing more than 7 million tons. The 2,920-foot-long dam has a base width of about 750 feet and tapers to 30 feet at the top on which a graveled road has been constructed. A concrete lined spillway has been constructed on the right abutment of the dam with a design capacity of 16,600 second-feet to divert water from the reservoir to accomodate flood flows. The outlet works, through which water normally flows, are on the left abutment and have a 2,310-sccond-foot capacity. A 3-foot-thick layer of soil cement has been placed on the upstream surface of the dam to protect it from erosion by wave action. i |
