The following conditions influenced this month's forecasts:

Precipitation:
Seasonal October through December precipitation was 75 percent of average in the Upper Green basin. December precipitation was 50 percent of average.

Snow:
January 1st snow water equivalent was near 55 percent of average in the basin as a whole.
--- Upper Green basin snow water equivalent plot.

Streamflow:
December streamflow was near 95 percent of average.

Soil Moisture:
Modeled soil moisture states ranged from below average to near average heading into the winter.

Climate Forecasts:
Climate forecasts were not a factor because there is not a strong correlation between El Nino conditions and winter precipitation in the Upper Green basin.

Forecast Summary:
Due to below average seasonal precipitation to date and much below average January 1st snow water equivalent values the April through July streamflow volume forecasts are below average at this time. These forecasts now range between 65 and 78 percent of average, with a median value of 75 percent.

The following conditions influenced this month's forecasts:

Precipitation:
Seasonal October through December precipitation was 95 percent of average in the Yampa/White basin. December precipitation was 110 percent of average.

Snow:
January 1st snow water equivalent was 80 percent of average in the basin as a whole.
--- Yampa basin snow water equivalent plot.

Streamflow:
December streamflow was near 90 percent of average.

Soil Moisture:
Modeled soil moisture states were near average heading into the winter for the Little Snake and White River basins. Modeled states ranged from below average to near average heading into winter for the Yampa basin.

Climate Forecasts:
Climate forecasts were not a factor because there is not a strong correlation between El Nino conditions and winter precipitation in the Yampa/White basin.

Forecast Summary:
Due to near average seasonal precipitation to date and below average January 1st snow water equivalent values the April through July streamflow volume forecasts are below average at this time. These forecasts now range between 76 and 86 percent of average, with a median value of 85 percent.

Soil Moisture:
Modeled soil moisture states were much below average to below average heading into the winter.

Climate Forecasts:
Climate forecasts were not a factor because there is not a strong correlation between El Nino conditions and winter precipitation in the Duchesne basin.

Forecast Summary:
Due to much below average seasonal precipitation to date and below average January 1st snow water equivalent values the April through July streamflow volume forecasts are below average at this time. These forecasts now range between 55 and 81 percent of average, with a median value of 75 percent.

--- Price basin snow water equivalent plot.

Streamflow:
December streamflow was near 90 percent of average.

Soil Moisture:
Modeled soil moisture states were much below average heading into the winter.

Climate Forecasts:
Climate forecasts were not a factor because there is not a strong correlation between El Nino conditions and winter precipitation in the Lower Green basin.

Forecast Summary:
Due to near average seasonal precipitation to date and below average January 1st snow water equivalent values the April through July streamflow volume forecasts are below average at this time. These forecasts now range between 73 and 84 percent of average, with a median value of 80 percent.

Differences between the full period forecasts and the residual forecasts may not exactly equal the actual observed volumes due to rounding conventions (see Definitions section).
