Much below average snowmelt runoff is expected throughout the eastern Great Basin this year. April-July volumes are expected to range mostly from 50 to 75 percent of the 1961-1990 average in the Great Salt Lake Basin and 50 to 60 percent of average in the Sevier Lake Basin. May was characterized by warm and dry conditions and most of the remaining snowpack has been depleted. Streams will be in recession throughout June and July with much below average runoff expected during this time.
