Measured snow <br />accumulation is 80% of average, which is only I % of average less than last month. There is 8% <br />less snow than last year at this time. There was 93% of average precipitation during the month of <br />April, and the water year total is at only 87% of average, which is 13% less than last year on May <br />I. The combined reservoir storage for 32 major reservoirs in the basin remains nearly the same as <br />last month at 88% of average May I. There is 14% less storage than last year at this time. Most <br />of the streamflow forecasts remain nearly the same as last month's, and all of them are below <br />average. Forecasts range from 66% of average at the Intlow to Antero Reservoir, to 89% of <br />average at South Boulder Creek near Eldorado Springs. <br />
