Water Year 2000 EA Releases Cont. 7-22 to 9-5 550 cfs EA releases were again increased by 150 cfs to maintain the 800 cfs flow target at Grand Island. By August 4, flows at Grand Island dropped below the 800 cfs target. Because the 550 cfs release was not maintaining the 800 cfs target and additional precipitation or a decrease in irrigation demand was not expected, the management objective was modified to include not only maintaining flows at Grand Island for fishlaquatic community health and tern forage base, but also to reserving some quantity of water in the EA for carry-over into the 2001 water year. 9-6 450 cfs EA releases were reduced in anticipation of the irrigation season ending and flows in the river improving. Reductions were made on an incremental basis so irrigation canals would not be adversely affected. 9-7 350 cfs See 9-6 comment above. 9-8 250 cfs See 9-6 comment above. 9-9 150 cfs See 9-6 comment above. 9-10 to present 0 cfs See 9-6 comment above. WATER YEAR 2001 PROJECTIONS AND EA RELEASE PRIORITIES Water Year 2001 Projected Water Sunnlv The Districts provided the following predictions for SNI and Type-of-Year for the 2001 water year to the EA Manager on October 13, 2000. Item S1vI, October through March SNI, October through April Type-of-Year Prediction 420,000 af 480,000 af Dry The October through April predicted inflow into Lake McConaughy as measured at the Lewellen gage was 485,000 af (STII excludes any storage water transferred from upstream reservoirs). The Type-of-Year is based on the predicted S1VI (420,000 a fl and Lake McConaughy carryover contents on October 1, 2000 (900,200 afl, in accordance with Section III of the EA Document. If the predictions hold true and no reservoir fill occurs, EA content by the end of the non-irrigation season will be about 90,000 af (i.e., 10% S1vI + Carry-Over - Evap./Seep. or 48K + 44K - 2K = 90K). Projected flows at Grand Island for the 2001 water year were compared to the Service's average and dry target flow recommendations (Figure 3).
