Above average accumulation throughout the basin has boosted the snowpack <br />from only 61 % of average on March 1, to 81 % of average on Apri11. The snow pack percentage <br />is highly variable depending on location in the basin, ranging from only 73% of average in the <br />Cucharas and Huerfano watersheds, to 108% of average in the Purgatoire Watershed. <br />Precipitation was 197% of average during March, and the water year total is now 109% of <br />average. The combined reservoir storage in the basin remains in great shape at 249% of average, <br />which is 20% more storage than last year at this time. The Clear Creek Reservoir is the only <br />reported reservoir with below average storage at only 81 %. Most of the streamflow forecasts <br />have improved due to the increased snowpack, but some areas have benefited significantly more <br />than others. Forecasts range from only 60% of average on Grape Creek near Westcliffe, to 108% <br />of average on the Cucharas River near La Veta. <br /> <br />~ <br />\ <br />I <br /> <br />.. <br />
