Figure 9 <br />South Platte River Basin as of April 1, 2003 <br />Snowpack conditions in the South Platte Basin have improved in one of the most dramatic fashions in <br />history. Measurements on April 1 are at 114% of average, which is 35°Io of average higher than the <br />March 1 measurements. Most of the increased snowpack occurred in a very short span of only three <br />days in mid-March, when blizzard conditions all along the Colorado Front Range delivered record <br />amounts of snow. There is well over two times the amount of snow there was last year at this time. <br />Precipitation during March was 204% of average, which is by far the highest monthly measurement this <br />water year. The water year total is now 113% of average. Reservoirs in the basin remain extremely low <br />for this time of year, at only 58% of average storage. There is only 68% of the amount of storage there <br />was last year at this time. The streamflow forecasts have improved significantly from last month's <br />forcasts. Forecasts range from only 42% of average at the inflow to Antero Reservoir, to 102% of <br />average on Boulder Creek near Orodell. <br />11rlountain Snowpack'" (inches) <br />?
