Missouri Reservoirs – July 1 system check - Gavins Point Dam releases will be set to provide navigation flow support at a level 500 cfs above minimum-service at all four target locations (Sioux City, Omaha, Nebraska City, and Kansas City). Flow targets may be missed to conserve water if there is no commercial navigation in a given reach. The navigation flow support season will be 3 days less than the normal 8-month season.
