The U.S. Army Corps of Engineers Northwestern Division hosted a Columbia River Basin Water Management Conference Call on Tuesday, July 14, 2015. The purpose of the ad hoc call was to provide information to stakeholders about current conditions, weather forecasts and planned operations of the Columbia River system as a result of dry-year conditions and to communicate how these conditions may impact the Columbia River Basin.
