  • Reduced releases from Gavins Point expected Friday

    Releases from Gavins Point Dam will be incrementally reduced to 20,000 cubic feet per second beginning Thursday. Releases should reach 20,000 cubic feet per second by Friday morning and will be held there through the weekend.

  • 2020 runoff forecast remains above average; Public meetings set for April 6-9 and April 14

    Gavins Point releases were decreased from 38,000 cubic feet per second to 35,000 cfs this week as tributaries downstream of Gavins Point began to rise due to the melting of the plains snowpack in South Dakota. The potential for above average runoff in the upper basin, coupled with continued high river stages on many of the uncontrolled tributaries downstream of the reservoir system, increases the potential for flooding, particularly in the lower river.

  • Gavins Point releases changing; changes will be more frequent

    The US Army Corps of Engineers plans to decrease releases from Gavins Point Dam from 38,000 cubic feet per second to 35,000 cfs tomorrow. Last week’s plan to increase releases to 41,000 cfs stopped at 38,000 cfs due to increased downstream runoff joining the Missouri River after Gavins Point Dam.

  • Gavins Point releases to increase; aimed at maintaining space for spring runoff

    The US Army Corps of Engineers plans to increase releases from Gavins Point Dam from 35,000 cubic feet per second to 41,000 cfs later this week, conditions permitting. The plan to increase releases is part of a commitment to remain as aggressive as possible with releases to maintain available flood control storage space in anticipation of above normal runoff for 2020.

  • Preparations to reservoir system continue for 2020 runoff season

    The U.S. Army Corps of Engineers continues to prepare the Missouri River Mainstem System for the 2020 runoff season. Gavins Point releases were increased from 30,000 cubic feet per second to 35,000 cfs this week. Gavins Point Dam winter releases normally range between 12,000 and 17,000 cfs.

  • Reduced releases from Gavins Point to address water supply concerns

    Releases from Gavins Point Dam will be reduced to 27,000 cubic feet per second on Wednesday, Jan. 22. Since increasing releases to 30,000 cfs on Jan. 7, the total storage at Gavins Point Dam has declined by 124,000 acre feet with the pool elevation dropping from 1207.7 feet to 1201.9 feet. “The pool level fluctuations at Gavins Point Dam have led to concerns that the lower pool level may affect access to water at some municipal water intakes on Lewis and Clark Lake,” said John Remus chief of the Missouri River Water Management Division.
