COLORADO BASIN <br />Basinwide Conditions Assessment <br />The SWSI value for the month was 2.5. Flow at the <br />gaging station Colorado River near Dotsero was 4240 cfs, as <br />compared to the long-term average of 2902 cfs. Storage in <br />Green Mountain, Ruedi, and Williams Fork reservoirs totaled <br />107% of normal as of the end of July. <br />Outlook <br />Considerably higher than average flows on the <br />upper Fryingpan River fell sharply in late July to at or below <br />average flows. However, Reudi Reservoir releases have <br />maintained the lower Fryingpan River at above average <br />flows. The Roaring Fork, Crystal, Blue, and Eagle river flows <br />remain considerably above average as of July 31St, keeping <br />Colorado river flows below Glenwood Springs approximately <br />125-130 percent of average. <br />Administrative/Management Concerns <br />Green Mountain Reservoir reached its maximum <br />desired content in early July requiring substantial release <br />rate increases on July 6t" and 7t". Release rates have since <br />been reduced from 1800 to 300 cfs as inflows have dropped <br />dramatically. Above average flows continue to prevent calls <br />on the Colorado and Blue Rivers through July. Contrary to <br />last months report, water users of the Colorado River and its <br />tributaries will likely not begin calls sometime in August. <br />Public Use Impacts <br />Lake Powell's increase peaked with an approximate <br />46 foot elevation increase as of July 16t" since March 6th <br />This brought the reservoir to 63 percent of its full pool <br />content of 24.32 million acre feet. <br />Aug-08 <br />COLORADO RIVER NR.
