OMAHA, NE - Higher-than-average releases from all Missouri River Mainstem System projects, including Gavins Point, will continue through November. To ensure all stored 2018 runoff is evacuated prior to the 2019 runoff season, most of the releases must occur before the river ices over in reaches predominantly upstream from Lake Oahe. The 2018 runoff forecast looks to be the third highest since record-keeping began in 1898. Runoff in the unregulated reach from Gavins Point Dam to Sioux City was 1.7 million acre feet for September and October, which is the highest in 120 years of record-keeping.
