SNAKE RIVER BASIN, Idaho/Ore./Wash. – Warming spring temperatures and recent rainfall in Idaho, and parts of eastern Washington and Oregon, are melting snowpack throughout the Snake River Basin. Corps reservoir managers are monitoring rivers and tributaries within the basin watershed, noting increasing flows from seasonal runoff. Some rivers in the basin are already at, or forecasted to soon reach, bankfull or flood-stage conditions, according to the National Oceanic and Atmospheric Administration’s (NOAA) National Weather Service River Forecast Center which can be found online at www.nwrfc.noaa.gov/rfc. The U.S. Army Corps of Engineers’ Walla Walla District activated its Emergency Operations Center at Level-3 yesterday afternoon, April 22, to more closely monitor seasonal flooding conditions throughout the Basin, according to District Readiness Division Disaster Response Manager Jeff Stidham.
