by Jim Fahey, Wyoming NOAA hydrologist
January 28, 2014

Initial 2014 Wyoming Water Supply Outlook and Graphic---January 15th
Wyoming December precipitation was nearly 120% of average.

Current water year precipitation is averaging nearly 135% of normal across Wyoming.

Mountain snowpack across Wyoming is 115-120% of average.

Near normal streamflow volumes are expected across major basins in Wyoming.

Wyoming reservoir storages are 85-90 % of average for January.

December precipitation totals Wyoming were nearly 120 % of average. Precipitation numbers varied between 215 % of normal over the Powder River Basin to near 45 % of normal over the Crow/Lodgepole Creek Drainages (Southeast Wyoming). Current water year (October-December 2013) precipitation across Wyoming is nearly 135 % of average.

Mountain snowpack across Wyoming was 115- 120 % of normal by early January. Snowpack "water" numbers and/or SWEs were the highest across northeastern Wyoming—varying between 140- 165 % of average. SWEs were the lowest across southwestern Wyoming---varying from 80 -100 % of normal.

Near normal (90 to 110 %) snowmelt streamflow volumes are expected across almost all major basins across Wyoming. Above average streamflow volumes are expected across the Powder River Watershed. The Lower Green, Sweetwater, and lower portions of the Wind River Basin are forecasted to have below normal streamflow volumes during the upcoming snowmelt season.

Reservoirs storages across Wyoming are slightly below average for January.
