<br />Reasonable.'Maximum Inflow Forecast <br /> <br />Green Mountain Reservoir <br /> <br />With a reasonable maximum inflow forecast, releases from Green Mountain Reservoir for <br />bypass of inflow, replacement, power, and river and reservoir regulation will average 3+5 <br />fels in February and March and will be increased in April to near ~ ft Is after ice <br />conditions permit to reduce the storage content to 55,000 acre-feet by April 30. Releases for <br />power will be increased, as required, from May through July to allow the reservoir to fill in <br />mid-July while minimizing the spill. June and July releases are expected to average near <br />~ Wis. The reservoir will remain nearly full throughout the remainder of the water year, <br />With reasonable maximum runoff, it is estimated that the cities of Colorado Springs and <br />Denver will deliver surplus water to the Blue River during April-September in the amount <br />of ~ acre-feet which would credit about 1.7 gigawatt-hours of power interference at the <br />Green Mountain Powerplant. . <br /> <br />Willow Creek Reservoir <br /> <br />Willow Creek Reservoir storage would reach a near maximum reservoir capacity of 10,200 <br />acre~feet by the; elld 6f Al'ril. With a Lake Granby spill forecasted and a reasonable <br />maximum runoff forecast, no water would be pumped to Granby during the April-July runoff <br />period. A total of71,999 acre-feet would be bypassed through the outlet works at Willow <br />Creek during April through July due to Lake Granby being at capacity and spilling. <br />Reservoir storage would remain at capacity through August and then would be pumped down <br />to 9,000 acre-feet by the end of the water year. <br /> <br />Lake Granby <br /> <br />Storage in Lake Granby will drop to a minimum of about ~95,209 acre-feet by the end of <br />April. Thereafter, Lake Granby storage will fill to its capacity 539,800 acre-feet (elevation <br />8280,00 feet) by mid-June, A spill of55,~99 acre-feet occurs in June and July as the east <br />slope reservoir storage is at capacity and Adams Tunnel diversions are maximized, <br />Reservoir storage of 528,799 acre-feet at the end of the water year would be 115,030 acre- <br />feet above the 30-year average of 413,670 acre-feet. <br /> <br />East Slope - Colorado-Big Thom,pson Proiect <br /> <br />With a reasonable maximum runoff forecast on February 1, below-average supplemental <br />project water demands equal to 153,799 acre-feet will be expected on the Project during <br />water year 1999. Diversions through Adams Tunnel will average about 3+5 Wls during <br />February.
