  • Team holds meetings across the region for Lower Missouri River system plan

    Officials will hold a series of public meeting for the Lower Missouri Flood Risk and Resiliency Study, also known as the system plan, throughout the region in April. The meetings, which will be held by the Kansas City District, U.S. Army Corps of Engineers and the Missouri Department of Natural Resources, will provide an overview of the study, a status update, input on reach measures, flow and stage frequency analysis update and an open discussion.

  • 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.   

  • Average Garrison Dam releases declining to address downstream ice

    **Updated to note continued decline in releases toward 16,000 cfs ahead of the forecast schedule.** Fluctuations in temperatures in the Bismarck area have resulted in ice formation on the Missouri River and an ice jam just south of Bismarck. To reduce the threat of flooding, releases from Garrison Dam will be decreased today to an average of 22,000 cfs and tomorrow to 19,000 cfs. Releases may be adjusted as needed over the next several days based on the most up-to-date information.

  • 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.

  • Missouri River navigation restoration efforts hit major milestone despite challenges

    2024 will mark five years since the historic flood of 2019 in Kansas City and the surrounding region. Water levels on the Missouri River reached heights not seen for decades and caused an estimated $2.9 billion in damages across the Midwest. While the historic flooding impacted many in the area in ways they will likely not soon forget, it might be hard to believe that just a couple of years after the historic flooding, the region entered a period of historic drought. With water levels now at historic lows, repairing the river’s navigation channel to its pre-flood condition has not been an easy feat.
