Much below to below average April-July runoff volumes are expected throughout the Eastern Great Basin this year. Forecasts changed little from those issued on April 1, except in the Six Creeks area, and range from 20 to 85 percent in the Great Salt Lake Basin and 50 to 85 percent of average in the Sevier Lake Basin. May 1 snowpack increased approximately 5% from April 1 in the Great Salt Lake Basin overall and decreased approximately 35% in the Sevier Lake Basin. However, snowpack increased 20% specifically in the Six Creeks area, resulting in higher forecasts in that area.
