During late March, the snowpack measurements peaked at about 55% ofthe <br />average peak, which usually occurs around mid-April. The warm, dry conditions have allowed the <br />snow to disappear about 37 days ahead of the average melt out date. The precipitation during May <br />was only 24% of average, which was the lowest monthly accumulation so far this water year. The <br />water year total is now only 53% of average, which is only 70% of the amount last year at this <br />time. The combined reservoir storage is at 66% of average, which is significantly less than last <br />month. There is 47% less water stored then there was last year at this time. As a result of the <br />continued dry, warm conditions during May, the streamflow forecasts have been lowered <br />significantly from last month's. They range from only 19% of average on Grape Creek near <br />Westc1iffe, to 25% of average on the Arkansas River at Salida. <br />
