A voJ.ume of supporting data presenting the latest in- <br />c")rmation on present and future ultimate transmountain diversions from the Colo- <br />r,do River Basin was nearing completion. System power operati~n was revised due <br />to additional data on sediment flow and Gunnison River depletions. System reser- <br />voir operation studies were made to determine maximum firm p~1er possible during <br />in;tial filling of the reservoirs with a construction schedule of the various <br />1'"fts as assumed in the interim report. These studies included operations 00- <br />.:).:ming in the Icy; flow period, in the high flow period, and a third beginning <br />'1ith an avera2e annual flow and assuming average annual flows during each year of <br />:f:;'lling period. ilevision of the Interim Project Report lIas nearing completion. <br />T~e sediment chapter of the Water Supply Appendix was completed.
