February 2012 Wyoming Spring Snowmelt Flood Potential Outlook

Quick Synopsis:

Snow water equivalents (SWEs) across Wyoming showed some improvement during January; but by early February, SWEs continued to be
below average across the majority of western, central, and southern Wyoming headwater watersheds.  Headwater creeks and streams along the Shoshone,  Powder, and Tongue Drainages continued to have above normal snowpack “water” numbers by early February.  

 

The Spring 2012 snowmelt flood potential outlook calls for:

 

...Moderate potential for snowmelt runoff flooding along headwater locations along the Powder (Clear and Rock Creeks), Tongue (Little and Big Goose Creeks), and eastern Big Horn (Shell Creek, Tensleep Creek, and Nowood River) Watersheds...

 

...Low to Moderate potential for snowmelt runoff flooding is also expected along the Little Snake River and its headwater streams (to include Savery Creek)...

 

Low to Moderate potential for headwater snowmelt flooding is expected across northern (upper sections) and southern Wind River Basin (Popo Agie River) and the Shoshone River Basin (North and South Forks)...

 

…All other headwater locations across Wyoming can expect a generally low potential for flooding due to springtime snowmelt...
