Rivers and creeks will continue to run near bankfull across central Fremont County through Sunday morning with some minor flooding possible. Most rivers and creeks either had crested or were cresting across central Fremont County on Saturday. Snowpack below the 10,000 foot level had mostly melted off and cooler temperatures are expected on Sunday, which will also reduce the rate of snowmelt runoff.

A Flood Warning remains in effect for the Little Wind River near Riverton until Sunday afternoon. The Little WInd River near Riverton crested at 8.2 feet Saturday morning and is expected to fluctuate around flood stage of 8.0 feet through Sunday morning. The river is expected to fall below flood stage Sunday afternoon and continue to gradually recede this week.

Graph of Snow Water Equivalent at the Hobbs Park Snotel Site which is located at 10,100 feet in the southern Wind River Range. The site has lost around 5" of water from Tuesday night through Saturday morning with little snowpack remaining. Snowmelt runoff from this area mainly drains into the North Fork of the Popo Agie River. (Click to Enlarge)	Hydrograph of the North Fork of the Popo Agie River northwest of Lander. The river should continue to recede over the next few days as snowmelt runoff rates decrease. (Click to Enlarge)
