  • Below-average runoff and reservoir storage expected for the Missouri River Mainstem System in 2025

    For the 2024 calendar year, Missouri River basin runoff above Sioux City, Iowa totaled 23.3 million acre-feet, 91% of average. Dry conditions continue to affect the upper Missouri River Basin at the start of the 2025 calendar year, so the U.S. Army Corps of Engineers is forecasting below-average runoff into the mainstem reservoir system. For 2025, runoff in the Missouri River basin above Sioux City, Iowa is forecast to be 20.2 MAF, 79% of average.
  • Columbia River environmental review begins, agencies seek input

    Two federal agencies are seeking public input on changed circumstances and new information regarding Columbia River System operations to inform preparation of a Supplemental Environmental Impact Statement (SEIS). The U.S. Army Corps of Engineers (USACE) and the Bureau of Reclamation (Reclamation), who are the co-lead agencies for the SEIS, issued a notice of intent in the Federal Register, today, which announced the effort and the need for public input over the next 90 days.
  • Don’t bet on the weather: The role hydropower plays in balancing the grid during extreme circumstances

    The power grid produces as it is consumed. Energy production rises and falls in tandem with human activity, allowing electricity to flow continuously into homes and businesses . However, this flow can be interrupted.
  • Gavins Point powerhouse annual maintenance in full swing

    Every year, the hydroelectric power generators at the Gavins Point Dam powerhouse, operated by the U.S. Army Corps of Engineers, Omaha District, are brought down one at a time to undergo annual maintenance. The maintenance begins in the fall when water releases are lower and concludes in early spring.
  • Gavins Point Dam releases reduced to winter release rate

    The U.S. Army Corps of Engineers began reducing the Gavins Point releases to the winter release rate on Nov. 23 with the navigation flow support season ending on Dec. 1 at St. Louis. “Releases from Gavins Point Dam are being reduced to the 12,000 cubic feet per second winter release rate by mid-December,” said John Remus, Chief of the 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.” Releases were at 32,000 cfs prior to the reductions.
  • 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.
  • Army planners, Washington State agree to study potential future recreation and transportation services

    Officials from the U.S. Army Corps of Engineers (USACE) and Washington State have entered into agreements to study recreation- and transportation-related services that could be needed if, in the future, Congress were to authorize the breach of the four lower Snake River dams.
  • McNary turns 70!

    As the population grew in the Pacific Northwest, communities formed around the Columbia and Snake rivers. Back then, the currents were temperamental and hard to navigate. However, there was a vision to create a highway, one that would allow barges to carry cargo from the Pacific Ocean to the confluence of the Snake and Clearwater rivers, 465 miles inland.
  • September runoff below average; October public meetings

    September runoff in the upper Missouri River Basin was well-below average, continuing the trend of below-average runoff in 2024. “Although Montana precipitation was wetter-than-normal in September, much of the basin was very dry and warm, causing the September runoff in all reaches above Gavins Point to be well-below average,” said John Remus, chief of the U.S. Army Corps of Engineers’ Missouri River Basin Water Management Division.
