The following conditions influenced this month's forecasts:

Precipitation:
Seasonal October through December precipitation was 95 percent of average in the Upper Green basin. December precipitation was 50 percent of average.

Snow:
January 1st snow water equivalent was 75 percent of average in the basin.
--- Upper Green basin snow water equivalent plot.

Streamflow:
December streamflow was near 110 percent of average.

Soil Moisture:
Modeled soil moisture states indicated near average to above average soil moisture conditions last fall prior to snow accumulation.

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

Forecast Summary:
Seasonal precipitation in the Upper Green is near average as a result of much above average precipitation in October and November. However, snow water equivalent is below average due to much below average monthly precipitation in December. It is also important to note that fall soil moisture conditions were near to above average. As a result, current April through July streamflow volume forecasts range between 65 and 87 percent of average with a median value of 80 percent.

The following conditions influenced this month's forecasts:

Precipitation:
Seasonal October through December precipitation was 70 percent of average in the Yampa/White basin. December precipitation was 30 percent of average.

Snow:
January 1st snow water equivalent was 65 percent of average in the basin.
--- Yampa basin snow water equivalent plot.

Streamflow:
December streamflow was near 120 percent of average.

Soil Moisture:
Modeled soil moisture states indicated above average to much above average soil moisture conditions last fall prior to snow accumulation.

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

Forecast Summary:
Seasonal precipitation is below average and snow water equivalent is much below average in the Yampa/White basins as a result of an extremely dry December. It is also important to note that fall soil moisture conditions were above to much above average. As a result, current April through July streamflow volume forecasts range between 68 and 83 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 90 percent of average in the Duchesne basin. December precipitation was 40 percent of average.

Snow:
January 1st snow water equivalent was 65 percent of average in the basin as a whole.
--- Duchesne basin snow water equivalent plot.

Streamflow:
December streamflow was 120 percent of average.

Soil Moisture:
Modeled soil moisture states indicated much above average soil moisture conditions last fall prior to snow accumulation.

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

Forecast Summary:
Seasonal precipitation in the Duchesne is near average as a result of much above average precipitation in October and near average precipitation in November. Snow water equivalent is much below average for the majority of the basin due to much below average monthly precipitation in December. However, the snow water equivalent for the eastern portion of the basin is near average resulting in somewhat higher forecasts. It is also important to note that fall soil moisture conditions were much above average. As a result, current April through July streamflow volume forecasts range between 63 and 104 percent of average with a median value of 80 percent.

The following conditions influenced this month's forecasts:

Precipitation:
Seasonal October through December precipitation was 80 percent of average in the Lower Green basin. December precipitation was 40 percent of average.

Snow:
January 1st snow water equivalent was 40 percent of average in the basin as a whole.
--- Lower Green basin snow water equivalent plot.

Streamflow:
December streamflow was near 130 percent of average.

Soil Moisture:
Modeled soil moisture states indicated near average to above average soil moisture conditions last fall prior to snow accumulation.

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

Forecast Summary:
Seasonal precipitation is below average and snow water equivalent is much below average in the Lower Green due to below average monthly precipitation in November and December. It is also important to note the fall soil moisture conditions were near to above average. As a result, current April through July streamflow volume forecasts range between 60 and 75 percent of average with a median value of 65 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).
