These basins received significantly above average amounts of snow for the month of January,
which has increased the snowpack percent of average from only 64% of average on January 1, to
84% of average on February 1. The Yampa and White basins have the highest snow pack percent
of average in the state at 88%, which is nearly the same amount as last year at this time. The
snowpack in the North Platte Basin is at 86% of average, which is 14% less than last year at this
time. Precipitation in these basins during January was 144% of average, but the water year total
is only 79% of average. The combined reservoir storage in these basins is at 115% of average,
which is about the same as last year at this time. The upcoming runoff season is still forecasted to
be below average at all of the forecast points in these basins. The forecasts are highly variable
depending on location and range from only 64% of average on the Laramie River near Woods, to
86% of average on the Yampa River at Steamboat Springs.
