" I I I I I I I I I I I I I I I I I I I Carter Lake storage will reach a maximum of 112,200 acre-feet for the water year in late March, and this is equal to the reservoir capacity. During March, Adams Tunnel and Olympus Tunnel diversions will continue to be near 490 ft3/s until March 17. To accommodate the Pole Hill Powerplant maintenance scheduled, diversions will then be minimized to prevent a bypass release. Adams Tunnel and Olympus Tunnel diversions will resume on March 30 when the Pole Hill Powerplant maintenance is completed and should be near 270 ft3/s through April 30. As runoff develops in late April and early May, Adams Tunnel diversions will be adjusted to accommodate runoff timing on the east and west slopes. Approximately 35,000 acre-feet of carryover irrigation water from the 1990 water year Colorado-Big Thompson Project quota water allotment wi 11 be delivered from April 1 through July 15. Horsetooth Reservoir is expected to reach a storage content of 142,000 acre-feet by the end of May, which is 14,700 acre-feet below the maximum reservoir storage of 156,700 acre-feet (elevation 5430.00 feet). Adams Tunnel diversion will be down to 4,700 acre-feet in June to take full advantage of operation "skim." Under operation "skim," approximately 47,600 acre-feet of Big Thompson River water will be diverted at Lake Estes through the Foothills Power System during April-September. The majority of "skim" water (44,900 acre-feet) will be diverted during May, June, and July. Irrigation demands will draft Horsetooth Reservoir storage to approximately 72,000 acre-feet by September 30. No water will be pumped to Carter Lake from May through September, and irrigation releases equal to 58,400 acre-feet will bring Carter Lake storage to near 49,000 acre-feet. The combined east slope terminal storage will be 98 percent of normal at the end of the water year. 22
