  • Corps reducing Gavins Point releases as Niobrara inflows decline

    Releases from Gavins Point Dam were reduced to 73,000 cubic feet per second (cfs) Saturday morning, March 16 and will reduced over the coming days reaching 20,000 cfs on Tuesday, the U.S. Army Corps of Engineers announced today. According to the National Weather Service, tributary flows into Gavins Point Dam, primarily from the Niobrara River have dropped significantly over the past 48 hours.

  • Gavins Point Releases Increasing

    The U.S. Army Corps of Engineers is increasing releases from Gavins Point Dam today in response to increased runoff into the Missouri River above the dam. Widespread rain and snowmelt has prompted the National Weather Service to issue flood warnings from southeast South Dakota to St. Louis.

  • 2019 runoff forecast above average; Public meetings set for April 9-11

    The 2019 runoff forecast in the Missouri River Basin above Sioux City, Iowa, is 28.4 million acre feet (MAF), 112 percent of normal, according to the U.S. Army Corps of Engineers (Corps) Missouri River Water Management Division. “The forecast increased about 10 percent from last month due to the continued accumulation of mountain and plains snowpack in the upper basin. Gavins Point releases will be increased from 18,000 cubic feet per second (cfs) to 20,000 cfs this week,” said John Remus, Chief of the Missouri River Basin Water Management Division.

  • Reservoir system prepared for 2019 runoff season

    All 2018 stored flood waters were evacuated from the Missouri River mainstem reservoir system (System) as of Jan. 29. The full 16.3 million acre-feet (MAF) of designated flood control storage is available to manage 2019 runoff. “The System stands ready to capture spring runoff, reducing flood risk while providing support to other authorized project purposes. Current Gavins Point releases are 20,000 cubic feet per second (cfs) and will be decreased to 17,000 cfs by mid-February,” said John Remus, Chief of the Corps’ Missouri River Basin Water Management Division.

  • System preparations for 2019 runoff season continue

    The U.S. Army Corps of Engineers continues to prepare the Missouri River Mainstem System for the 2019 runoff season. Current Gavins Point releases are 20,000 cubic feet per second. Gavins Point releases will be increased to 24,000 cfs this week. “The higher-than-average winter releases from Gavins Point will continue the evacuation of the stored flood waters from the 2018 runoff season,” said John Remus, Chief of the Corps’ Missouri River Basin Water Management Division. “These releases will provide additional hydropower generation during the winter, which is one of the peak power demand periods. In addition, the higher-than-average releases will benefit municipal and industrial water intakes below Gavins Point Dam, which can be impacted by low water levels during periods of ice formation,” added Remus. Gavins Point Dam winter releases normally range between 12,000 and 17,000 cfs.
