All of the watersheds managed to receive additional snow accumulation during <br />February, but the Animas and the Dolores watersheds were by far the biggest winners with some <br />of the largest increases in snowpack percent of average in the state. The lower elevations and <br />valleys only received 84% of average precipitation during February, and the water year total is <br />now only 43% of average. The combined reservoir storage level in these basins remains at 116% <br />of average for this time of year, which is 16% more storage than last year at this time. All of the <br />forecasted streamflows for this runoff season remain below average, but the improved snowpack <br />conditions have allowed many of the forecasts to improve as well. The forecasts are highly <br />variable and range from 50% of average on the Rio Blanco at Blanco Diversion, to 82% of <br />average on the San Miguel River near Placerville. <br /> <br />I' <br /> <br />'( <br />
