As of February 1st below to much below average April-July runoff is expected throughout the Eastern Great Basin. Forecasts are expected to range from 50 to 85 percent of the 1961-90 average in the Great Salt Lake Basin and 65 to 95 percent of average in the Sevier Lake Basin. Much below average January precipitation in the Great Salt Lake Basin resulted in a 10% decrease in the snowpack overall and a subsequent decrease in the spring runoff forecasts. In contrast, near average January precipitation in the Sevier Lake Basin resulted in little change to the spring runoff forecasts in that area.
