Thc amounts arc about 86% of average this month, which is only I % of average <br />highcr than last month. Unless this spring season is unusually wet, the snowpack measurements <br />are unlikely to improve significantly between now and when the mehout begins. The snowpack <br />measurements are relatively uniforn! ranging from 81 % of average in the Uncompahgre <br />Watershcd, to 88% of average in the Upper Gunnison Watershed. Precipitation during March <br />was 88% of averagc, and the watcr year total is now 86% of average. There has been 29% morc <br />precipitation this water year compared to last water year by this time. Reservoir storage has <br />begun to improve slightly, and now is 81 % of average. There is only 71 % of the amount there <br />was last year at this time. Unfortunately, most of the streamflow forecasts havc not improved <br />since last month. All of the forecasts remain well below average and many have decrcased since <br />last month. They range from only 56% of average on the Uncompahgrc River at Colona, to 84% <br />of average on Tomichi Creek at Sargents. <br />
