Green River Outlook

Wet, cool conditions during the first half of April resulted in an increase in the mountain snowpack through mid-month. Snowmelt occurred at all elevation levels during the latter part of April due to warm, dry conditions. Significant loss was observed at low and middle elevations. May 1 snowpack remained much below average in most areas except for near average at high elevations in the eastern Duchesne Basin. Forecasts range mostly from 30-70% of average flows.
