As a result, snowpack levels remain at only 55% of average and are only 54% <br />of last year's snowpack, At least cooler temperatures during April, helped to slow the melt which <br />began in March. Precipitation during April was 10 I % of average offering only a slight <br />improvement to the water year totals which are only 83% of average. Reservoir storage is more <br />than two times that of last year, but remains below average, The eight major reservoirs in the <br />basin are reporting a combined storage of 89% of average, Runoff prospects throughout the <br />Colorado Basin are very poor this year. Most of the forecasts along the main stem range from <br />58% to 60% of average. The highest forecast volumes, as a percent of average, occur along the <br />tributaries toward the south and include the Roaring Fork, Eagle, Blue and William's Fork. <br />Forecast volumes along these reaches range from 63% to 66% of average. <br />
