Measurements on April I are at 114% of average, which is 35% of average <br />higher than the March I measurements. Most of the increased snowpack occurred in a very short <br />span of only lhree days in mid-March, when blizzard conditions all along the Colorado Fronl <br />Range delivered record amounts of snow. There is well over two times the amounl of snow there <br />was last year at this time. Precipitation during March was 204% of average, which is by far the <br />highest monthly measuremenlthis water year. The water year lotal is now 113% of average. <br />Reservoirs in the basin remain extremely low for this time of year, at only 58% of average <br />storage. There is only 68% of the amounl of slorage there was last year atlhis time. The <br />streamflow forecasts have improved significantly from last month's forcasts. Forecasts range <br />from only 42% of average at the inflow to Antero Reservoir, to 102% of average on Boulder <br />Creek near Orodel!. <br />
