Show Upper Provo River Reservoir Stabilization The upper Provo River area contains many natural lakes, 15 of which have had additional water impounded by dams. These reservoirs have a total capacity of 13,000 acre- feet and provide late season irrigation water for downstream appropriators. The reservoirs have fluctuated widely in the past. Filling usually occurs through winter months with maximum water surface increases during the months of April and May. Drawdown begins in about July and is complete by late August. 2 The Forest Service has recommended that Ik of these lake- reservoirs be converted to permanent lakes with stabilized capacities and water levels. Reconstruction of some of the dams is proposed. One lake would continue to be utilized to store 2,030 acre- feet of irrigation water for use on lands above Jordanelle Reservoir. That lake would continue to fluctuate as in the past. The reservoirs are accessible by road and trail. Six of these lakes are near existing roads, and one additional lake will be served by a new road- according to the Wasatch National Forest transportation plan. Trail access only would be provided to the remaining eight lakes. Physical data on the 15 reservoirs are shown in Table A- 7. Jordanelle Reservoir Jordanelle Dam and Reservoir would be located on the Provo River about 6 miles north of Heber City. It would provide storage of Bonneville Unit water at an upstream site by exchange for Bonneville Unit water in Utah Lake and most of the water that is presently regulated in 15 small reservoirs on the headwaters of Provo River. Municipal and industrial water stored in Jordanelle Reservoir would be delivered to Salt' Lake County through the Provo. River, the rehabilitated Provo Reservoir Canal, and the buried Jordan Aqueduct and to northern Utah County through the Provo River and the proposed Alpine Aqueduct. Jordanelle Reservoir would be a long- term holdover reservoir. The maximum content would occur during periods of high inflow and low demands, and the minimum content would occur during periods of low inflow and high demands. The reservoir would have emptied only once in the 40- year period from 1921 through I960. 91 |
