COLORADO BASIN <br />Basinwide Conditions Assessment <br />The SWSI value for the month was 2.0. Flow at the <br />gaging station Colorado River near Dotsero was 8113 cfs, as <br />compared to the long-term average of 5517 cfs. Storage in <br />Green Mountain, Ruedi, and Williams Fork reservoirs totaled <br />113% of normal as of the end of June. <br />Outlook <br />The Colorado River and all major tributaries peaked <br />during the month of June and remain at nearly twice the <br />levels seen at this time last year. No significant flooding is <br />expected. Ruedi Reservoir will not likely reach typical <br />summer level following the large releases in early June as <br />part of the fish recovery program near Grand Junction. <br />Fryingpan River flows have fallen substantially since July 1St <br />despite Fryingpan-Arkansas trans-mountain diversions <br />through Boustead Tunnel decreasing by over one third since <br />July 3rd. <br />AdministrativelManagement Concerns <br />Continued above average flows continue to prevent <br />calls on the Blue River as well as those from Shoshone and <br />Grand Valley Irrigators. Users of tributaries to the Roaring <br />Fork, Crystal, and Colorado Rivers will not begin calling until <br />July. <br />Public Use Impacts <br />The forecast 45-50 foot elevation increase in Lake <br />Powell is laying out with a 43 foot rise as of June 30 since <br />March 10 . The Castle Rock Cut marina opened on June <br />10t" for the first time in 5 years, with the lake reaching its <br />highest level since 2002. The Bureau of Reclamation is <br />forecasting an additional 6.5 feet elevation increase in July. <br />Jul-08 <br />7 <br />
