1. '34"1 . B. West Slope Co11eetion System The Project imports during the 1984 runoff year as measured at Charles H. Boustead Tunnel (Boustead Tunnel) outlet were 73,680 acre- feet (see table 2). Of this total, 2,500 acre-feet was diverted during October and November of 1984. The APl1i 1 1 forecasted import for May through September was for 69,010 acre-fe~t. I The following minimum bypass require~ents at the various diversion points were used during the 1985 operatipn: Divers ion poi nt Minimum bypass requirement (ft3/s ) 12 6 3 o o 3 1 1 o 2 12 5 4 2 1 o .

This minimum requir~ment i$ as follows: April - 100 cubic feet per second, May - 150 eubic feet per second, June - 200 cubic feet per second, July - 100 cubic feet per sdcond, August - 75 cubic feet per second, and September - 70 cubic feet iper second or the natural flow, whichever is less. ' When it appears that these flows will !not be met, the diversions into the Project system are decreased or stqpped, whichever is necessary to meet the bypass requirements. The Hu~ter Creek System, whieh drains into the Roaring Fork River, can contin~e diverting water into 80ustead Tunnel during these times.
