  • Changing Fort Peck ice conditions

    Flows through Fort Peck powerhouses will decrease through March 4. These flow reductions may impact ice conditions below the dam on the river and dredge cuts. Recreationists on the ice, both below and above the dam, are urged to use extreme caution.

  • Below average runoff forecast for the upper Missouri River Basin in 2022

    The updated 2022 calendar year runoff forecast for the Missouri River Basin above Sioux City, Iowa, continues to be below average.  “Despite January’s runoff being slightly above average, we expect 2022 runoff to remain below average,” said John Remus, chief of the U.S. Army Corps of Engineers’, Missouri River Basin Water Management Division. “Both plains snowpack and mountain snowpack continue to lag behind seasonal averages, and soil moisture continues to be much drier-than-normal.”

  • Dry Conditions expected to persist for the Missouri River Basin

    The 2021 calendar year runoff summation for the Missouri River basin above Sioux City, Iowa was 15.2 million acre-feet, 59% of average. The ongoing drought shows no relief in sight and the U.S. Army Corps of Engineers is predicting runoff into the mainstem reservoir system will remain below normal. This was the 10th lowest annual runoff for the Missouri River Basin in 123 years of record-keeping.

  • 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, marking the end of flow support for the 2021 Missouri River navigation season. “Releases from Gavins Point Dam are being reduced to the winter release of 12,000 cubic feet per second,” said John Remus, Chief of the Missouri River Basin Water Management Division. “Releases from Gavins Point are currently 13,000 cfs and we will slowly reduce releases to 12,000 by December 8. We will closely monitor river conditions, and releases will be adjusted this winter as needed to lessen the impacts of river ice formation on stages in the lower river.”

  • Gavins Point Dam releases to be reduced in late November

    “We will continue to make releases from Gavins Point Dam to provide flow support at an intermediate service level, 1,500 cubic feet per second (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.

  • Dry conditions persist in Upper Missouri River Basin; Public meetings set for Oct. 25-29

    September precipitation was once again below average in the Missouri River Basin. September runoff in the Missouri River Basin above Sioux City, Iowa (upper Basin) was 0.8 million acre-feet, 67% of the long-term average. Soil conditions in the upper Basin continue to be very dry. According to the Drought Mitigation Center, approximately 88% of the Missouri River basin is currently experiencing some form of abnormally dry conditions or drought, which is a 6% increase from the end of August.

  • Environmental Impact Statement completed for Fort Peck Dam

    The U.S. Army Corps of Engineers, Omaha District has publicly made available the final Environmental Impact Statement (EIS) for test releases from Fort Peck Dam, Montana. The purpose of the EIS is to assess the capacity of test flows from the Fort Peck Dam to promote the growth and survival of the pallid sturgeon, a fish species listed as endangered under the Endangered Species Act of 1973.

  • Winter Gavins Point releases will be at minimum rates

    Updated: Fort Peck release reductions was incorrectly reported as Sept 6 and has been corrected to Sept. 16. Drought conditions, particularly in the Missouri River Basin above Sioux City, Iowa (upper Basin), are persisting. Per the Master Manual and the Sept. 1 System storage check, winter releases from Gavins Point Dam will be 12,000 cubic feet per second, as part of the overall water conservation measures. “Reservoir inflows in August were much lower than average. We expect below-average inflows into the System through the rest of 2021,” said John Remus, chief of the U.S. Army Corps of Engineers’ Missouri River Basin Water Management Division.

  • Drought conditions persist in the upper Missouri River Basin

    Drought conditions continue to impact the upper Missouri River Basin above Sioux City, Iowa (upper Basin). July runoff in the upper Basin was 34% of average. July runoff above Fort Peck Dam was the lowest in 123 years of record-keeping. The updated 2021 upper Basin runoff forecast is 14.6 million acre-feet (MAF), 57% of average. If realized, this runoff amount would be the 10th driest year in the upper Basin since 1898. System storage on August 1 was 53.9 MAF, 2.2 MAF below the base of the Annual Flood Control and Multiple Use Zone. System storage is expected to decline further into the Carryover Multiple Use Zone during the remainder of 2021.

  • Vegetation control set for invasive species located at Fort Peck Reservoir, Montana

    FORT PECK, Mont. -- The U.S. Army Corps of Engineers, Omaha District will conduct vegetation management activities beginning the week of August 8, 2021, on the Seven Blackfoot, Billy, Wilson, McCarty, Sheep, Short, Cart Trail, Armstrong and Doney drainages, as well as the shoreline between Seven Blackfoot and Billy drainage located at the Fort Peck Reservoir in Garfield and Phillips Counties, Montana.
