  • Despite early runoff, upper basin runoff forecast below average; Gavins Point releases to increase for navigation flow support

    A warm February led to increased snowmelt and runoff in the Missouri River Basin above Sioux City, Iowa. February runoff was 1.8 million acre-feet, 161% of average with above average runoff in every reach except Sioux City, which was near average. However, the updated 2024 calendar year runoff forecast for the basin continues to be below average.   

  • Below average runoff forecast for the upper Missouri River Basin in 2024

    **Last paragraph to note Forecast generation for 2024 is 8.6 billion kWh. It had been incorrectly stated as 2023.** The updated 2024 calendar year runoff forecast for the Missouri River Basin above Sioux City, Iowa, continues to be below average. January runoff in the Missouri River Basin above Sioux City was 0.4 million acre-feet, 56% of average. Runoff was well-below-average due to much-below-normal temperatures over the whole Missouri River Basin and below-normal precipitation over most of the upper basin.

  • Dry conditions expected to persist for the Missouri River Basin

    For the 2023 calendar year, Missouri River Basin runoff above Sioux City, Iowa totaled 30.4 million acre-feet (MAF), 118% of average. Despite the above average runoff last year, the U.S. Army Corps of Engineers is forecasting below-average runoff into the mainstem reservoir system this year. For 2024, runoff in the Missouri River Basin above Sioux City, Iowa is forecast to be 20.1 MAF, 78% of average.

  • Now Available: Final 2023-2024 Missouri River Operating Plan

    The Final Missouri River Mainstem Reservoir System Annual Operating Plan for the 2023-2024 runoff season is now available. This Annual Operating Plan (AOP) presents the U.S. Army Corps of Engineers’ regulation of the Missouri River Mainstem Reservoir System through Dec. 2024. The information in the AOP is based on water management guidelines designed to meet the reservoir regulation objectives of the 2018 Missouri River Master Water Control Manual (Master Manual).

  • Evaluation of Operational Changes to Facilitate Hydropower Production at Summersville Lake, West Virginia

    The U.S. Army Corps of Engineers (USACE), pursuant to Section 146 of the Water Resource Development act of 2020 and through a request from the City of Summersville, is undertaking an evaluation to consider operational changes at the Summersville Lake. This evaluation will evaluate potential operational changes to facilitate production of non-federal hydropower which are consistent with the authorized purposes of the project

  • Gavins Point Dam releases reduced to winter release rate on November 23

    The U.S. Army Corps of Engineers began reducing the Gavins Point releases to the winter release rate on November 23 with the navigation flow support season ending on December 1 at St. Louis, MO. “Releases from Gavins Point Dam were reduced from 35,000 cubic feet per second to 13,000 cfs by mid-December,” said John Remus, chief of the USACE, Missouri River Water Management Division. “We will closely monitor river conditions, and releases will be adjusted to the extent practical to lessen the impacts of river ice formation on stages in the lower river.”

  • Barkley Power Plant charged to safely generate hydroelectricity during rehabilitation

    The team at the Barkley Dam Power Plant is generating hydroelectricity daily to provide green energy to the region but is also working to operate the plant safely while a hydropower unit is dismantled during a multi-year rehabilitation project that will encompass all four units.

  • Gavins Point Dam releases to be reduced to winter release rate

    Gavins Point Dam releases will be reduced in late November as flow support to navigation ends. Releases are currently 32,000 cubic feet per second. “We will continue to make releases from Gavins Point Dam to provide flow support at an intermediate service level, 1,500 cfs less than full service, through the end of the navigation flow support season,” said John Remus, chief of the USACE, Missouri River Water Management Division.  “The flow support season will end on Dec. 1 at the mouth of the Missouri River.”
