  • 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.

  • Drought conditions persist in Missouri River Basin through July

  • System operations returning to normal post flooding

    Significant rainfall led to an above average runoff in the upper Missouri River Basin. June runoff was 6.6 million acre-feet, which is 119% of average and 2.6 MAF higher than forecast. A strong weather system moved into the basin on June 21 producing excessive rainfall in eastern South Dakota, north central and northeastern Nebraska, and northwestern Iowa. The rainfall totals exceeded 600% of normal over the 24-hour period.
