This is 21 % less snow then there was last <br />year at this time. Snowpack percentages are relative!y uniform throughout the basin, ranging <br />from only 59% of average in the Cucharas and Huerfano watersheds, to 68% of average in the <br />Purgartoire River Watershed. The precipitation during February was only 66% of average, and <br />. the wat~r year total is now only 64% of average. The combined reservoir storage remains at 78% <br />of average, which is the same as last month, bUl can be expected to fall if snowpack and <br />precipitation conditions do not improve over the next month. There is 34% less water stored then <br />there was last year at this time. All ofthe streamflow forecasts remain well below average at this <br />time. They range from only 51 % of average on the Cucharas River near La Veta, to 70% of <br />average on the Arkansas River at Salida. <br />
