<br />i '1 '2~ <br /> <br />. <br /> <br />Twin Lakes and Mt. Elbert Forebay (a single purpose storage facility for <br />pumped-storage peak power development) were operated for regulation of <br />Project and non-Project water on a service basis, as well as for the <br />operation of Mt. Elbert Pumped-Storage Powerplant. <br /> <br />Pueblo Reservoir was operated for regulation of Project and non-Project <br />water on a service basis, as well as for flood control, fish and <br />wildlife, and recreation purposes. <br /> <br />III. REPORT ON OPERATIONS OURING WATER YEAR 1986 <br /> <br />A. Ruedi Reservoir <br /> <br />Ruedi Dam is located on the Fryingpan River on Colorado's western <br />s lope. The reservoir provides replacement storage for out-of-priority <br />depletion by the Project. Additional storage water is available for <br />sale to meet irrigation and municipal and industrial water needs in <br />western Colorado. <br /> <br />The reservoir has a total capacity of 102,300 acre-feet. The spillway <br />on the right abutment is uncontrolled with an ogee-type crest and has a <br />total release capability of 5,500 cubic feet per second. <br /> <br />Storage in Ruedi Reservoir coming into water year 1986 (September 30, . <br />1985) was near capacity at 93,200 acre-feet. By mid-November the reser- <br />voir release was increased to 190 cubic feet per second to accomplish <br />winter drawdown. This release rate was maintained until early April <br />when it was increased to 250 cubic feet per second to bypass spring <br />snowmelt. During May and June, releases were further adjusted to assure <br />refi 11 of the reservoir by early July. The maximum daily release <br />occurred on June 14 at 536 cubic feet per second. Thereafter, releases <br />were adjusted to stabilize the reservoir water surface elevation <br />about 2 feet below the spillway crest. The maximum reservoir content <br />reached during the year was 102,000 acre-feet on September 17. The <br />inflow slowly declined to approximately 140 cubic feet per second on <br />September 30, 1986. <br /> <br />During water year 1986, no requests were made for releases of stored <br />water by the storage contract entities. The content on September 30, <br />1986, was 100,900 acre-feet. <br /> <br />Exhibits 1 and 2 show the precipitation and pan evaporation at Meredith. <br />Table 1 and exhibit 3 show the operations of Ruedi Reservoir during <br />water year 1986. <br /> <br />B.
