<br />the reservoir to fill without spill by the end of July. With minimum <br />irrigation releases in August and September, normal carryover storage <br />would exist in Boysen Reservoir by the end of the water year. With <br />limited powerplant capacity due to maintenance, Buffalo Bill Reservoir <br />would only be lowered to about 343,000 acre-feet content by March 31. <br />With continued releases at available capacity, the reservoir would <br />fill during June with over 275,000 acre-feet of water bypassing the <br />units. System energy imports would average about 44 million kilowatt- <br />hours through March, then cut back to an average of 5 million kilowatt- <br />hours through August. Surplus generation would be available during <br />June. Moderate import of energy would resume in September. <br /> <br />With reasonable m~nimum inflow, operations would be similar to most <br />probable inflow conditions, except that Green Mountain Reservoir would <br />be lowered to 60,000 acre-feet by the end of April. All available <br />water totaling 27,000 acre-feet would be pumped from Willow Creek <br />Reservoir to Lake Granby during the season. Adams Tunnel diversions <br />would be increased from February through May in anticipation of high <br />irrigation demand. Storage in Lake Granby would be lowered to about <br />282,000 acre-feet by the end of April and fill to only 380,000 acre- <br />feet by the end of July. Colorado-Big Thompson Project storage <br />reserves would be depleted by over 140,000 acre-feet in meeting an <br />estimated supplemental irrigation delivery of over 291,000 acre-feet. <br />Releases from Seminoe would be similar to the most probable inflow <br />condition but the reservoir would fill to only 410,000 acre-feet by <br />the end of June. Downstream demands would allow normal evacuation <br />of Pathfinder Reservoir to 50,000 acre-feet content by the end of <br />the year. With full irrigation delivery to all North Platte users, <br />operation of other facilities would be similar to most probable <br />inflow' conditions. If a full irrigation delivery were made, with <br />no accrual, Kendrick storage ownership would decrease to 259,000 <br />acre-feet. North Platte Project and Glendo Unit ownerships would <br />decrease by 425,000 and 29,000 acre-feet, respectively. After <br />winter drawdown,releases from Boysen Reservoir would be limited <br />to minimum requirements throughout the season. Boysen Reservoir <br />would fill to 690,000 acre-feet by the end of June, and carryover <br />storage would be well below normal at the end of the water year. <br />Buffalo Bill Reservoir would fill during June, and near-normal carry- <br />over storage would exist at the end of the water year. Power imports <br />would be s~milar to most probable inflow conditions through May. No <br />appreciable energy would be required thereafter. Surplus generation <br />would. be available in June. Generation would be virtually equal to <br />load during the remainder of the season. <br /> <br />With reasonable maximum inflow, operations would be similar to most <br />probable inflow conditions, except that Green Mountain Reservoir <br />would be lowered to 40,000 acre-feet by the end of April. Pumping <br />from Willow Creek Reservoir to Lake Granby would be limited to <br />64,000 acre-feet. Willow Creek Reservoir would remain full at the <br /> <br />vi <br />
