                     SPRING FLOOD POTENTIAL
          FOR THE GREEN AND BEAR RIVER BASINS IN WYOMING

                       JANUARY 5, 2017


The 2017 spring runoff flood potential due to snowmelt is
difficult to determine at this time of year for the Upper
Green and Bear River basins. It is very early in the snow
accumulation season and conditions can change before runoff
begins. However, the snowpack in the Upper Green and Bear River
basins is currently above normal for this time of year but is
still much below the typical seasonal snow accumulation peak.

December precipitation and water year precipitation
(October-December) are currently both much above average
for river basins in southwest Wyoming. Precipitation and
snow conditions as of January 1st are listed below.

PRECIPITATION AND SNOWPACK (% OF AVERAGE):

The spring runoff flood potential will be re-evaluated in early February and an updated
product will be issued at that time.
