<br />. <br /> <br />. <br /> <br />. <br /> <br />WATER SUPPLY <br /> <br />cOlHpl etion, ~uld start filling at the beginning of Fiscal Year 1963. <br />All the l'el"ervoirs would fill to reasonable operating levels by March 51, <br />1971, and the major part of the system pover output at the three storage <br />units would then be attained. An annual summary of the initial filling <br />operation for the Glen Canyon Reservoir with allowance for filling of <br />the storage project upstream reservoirs is shown on the following page. <br /> <br />The post-filling reservoir operation study was based on several <br />repetitions of a runoff cycle similar to the 32-year runoff period 1914 <br />to 1945. Data corresponding to the 32 years in sequence were inserted <br />in the study for Fiscal Year 1971 through Fiscal Year 2002 and the <br />process was repee,ted for each 32 years thereafter with proper adjust- <br />ments for increased depletions. A~ual releases for system energy <br />generation vere made in varying amounts in accordance with normal <br />operating and forecast procedures. The monthly pattern of releases for <br />energy generation folloved the pattern of energy requireoents estimated <br />for 1980 in the project power market areaY. Additional releases made <br />in anticipation of 1",-::e1' spLlls WSl"e a11"0 utili zed in the generation <br />of energy. <br /> <br />!/ Pattern of energy requirements was taken from preliminary data <br />for a power market survey that is being made by th1e Fed..ral Pmrer Com.- <br />mission for the Colorado River Storage pro.ject. <br /> <br />19 <br />
