<br /> <br />o <br />o <br />... <br />~ <br />t..) <br />~ <br /> <br />Flatiron Pump/Generator Unit 3 was inoperable for about 9 months due to the explosion. The <br />only method of diverting water to Carter Lake is through Flatiron Pump/Generator Unit 3. <br />Therefore, no water was pumped to Carter Lake during the 9 month outage. Pumping resumed <br />to Carter Lake on September 4, 1996, following the rebuild of Flatiron Pump/Generator Unit 3. <br />A total of about 45,000 acre-feet of water was spilled at Lake Granby due to shutdown of the <br />pump and the high runoff condition. <br /> <br />February temperatures over the Project were varied. February precipitation was much above <br />average ranging from 148 percent of average for the Poudre watershed to 238 percent of average <br />for the Green Mountain watershed. March 1 snowpack continued to be high ranging from 141 <br />percent for the Poudre watershed to 200 percent for the St. Vrain watershed. . <br /> <br />March was fairly typical with rain, wet snow, some sunny weather, warm days, cold days, and <br />plenty of wind. Precipitation for March was varied with the Green Mountain watershed at 86 <br />percent of average and the Poudre watershed at 169 percent of average. .snowpack water content <br />averaged 154 percent over the Project watersheds for April L On April I, Green Mountain <br />recorded 22.8 inches; Willow Creek recorded 12.6 inches; Lake Granby recorded 17.8 inches; and <br />St. Vrain recorded 17.5 inches, respectively. Percent of average ranged from 131 percent at the <br />Willow Creek watershed to 186 percent for the St. Vrain watershed. Temperatures over the <br />Project were near average for March, although Denver, Colorado set a record low temperature <br />on March 25 of _20F. <br /> <br />The high storage condition and high forecasted runoff, along with the inability to deliver water to . <br />Carter Lake, resulted early bypass releases from Lake Granby and Willow Creek Reservoir to <br />reduce the amount spilled in June and July. The water year 1996 bypass/spill from Lake Granby <br />totaled 72,800 acre-feet and 49,743 acre-feet from Willow Creek Reservoir; <br /> <br />April weather usua11y produCes significant storm systems that move through the Project. area, but <br />this April was warm and dry. Precipitation was.. much.. below average over the Project during April <br />except for Gr~en Mountllin, tangirtgfrom 52 percent of average for Willow Creek and Grariby <br />watersheds to 110 percent of average for the Green Mountain watershed. This decreased the <br />April 1 snowpack to 144 percent of average for the Project area. Temperatures were varied for <br />April and Fort Collins, Colorado set a record hightemperature for April 24 at 84 oF. <br /> <br />May was a dry month on the west slope and dry on the east slope until the last week of May. <br />Precipitation ranged from 71 percent of average for Willow Creek and Granby watersheds to 216 <br />percent of average for the Lake Estes and St. Vniin watersheds. Temperatures for May were <br />generally above average. Record high temperatures were set for Denver on May 15 at 890F and <br />May 16 at 93 OF and for Fort Collins on May 16 at 88 OF. <br /> <br />June brought a combination of above average temperatures and varied precipitation, which <br />resulted in the October-June precipitation at 144 percent of average for the Project. July <br />precipitation was varied and August precipitation was below average for all Project watersheds. <br />Green Mountain Reservoir spilled 20,290 acre-feet in June and 5,388 acre-feet in July due to the <br /> <br />2 <br /> <br />_ , :1,- ?F~:~~,,:~~;:l::?:1'!':;f;~~;:'-~~~:-:W::..::~::Y,:;";!::;.:_:;;<,;;,";V'~:~.~~:~'~~~>~$r.r.~;:::"*;;:;:rg...'I:;~,;~~m~,~t"J'?,.'~::.,I'I'.C"",,.........,., .~.~ <br />
