April-July runoff forecasts have been increased throughout the eastern Great Basin as a result of an abnormally cool and wet April. Runoff volumes are expected to generally range between 70 to 110 percent of the 1961-1990 average in the Great Salt Lake Basin and 45 to 75 percent in the Sevier Lake Basin. Although lower elevation snowpack has been depleted, the cooler weather in April has delayed the onset of snowmelt at middle to high elevations. May 1 snowpack at these higher elevations is highly variable, ranging mostly between 80 to 160 percent of average in the Great Salt Lake Basin and 40 to 120 percent of average in the Sevier Lake Basin.
