April Streamflow Forecast Above Average
   
All eight watersheds in the Colorado-Big Thompson Project continued to receive precipitation during March. Generally, the gains in snowpack were typical for March. This resulted in very little fluctuation between the March and April forecasts. In all eight watersheds, the most probable forecast remains above average.  See the April 2014 Streamflow Forecast.
