  • Jamestown and Pipestem Reservoirs snowmelt update

    Snowmelt inflow is occurring at Jamestown and Pipestem Reservoirs, and pool elevations have been increasing as expected. Large river flows continue upstream of the reservoirs and high inflows are expected to continue for the next few weeks. Combined releases from the reservoirs are currently expected to stay below 1200 cubic feet per second; significant additional rainfall or snow may necessitate higher release levels. Pipestem Reservoir is currently at pool elevation 1460.1 feet which results in 16.6 percent of the flood pool occupied. Jamestown Reservoir is currently at pool elevation 1431.8 feet which results in 1 percent of the flood pool occupied.
  • Corps seeks public comment on Draft Supplemental Environmental Assessment, Hole-in-the-Rock backwater excavation

    A draft supplemental environmental assessment for the renovation of a previously constructed backwater habitat at Hole-in-the-Rock is currently available for public review. The draft supplemental EA evaluates the environmental impacts of restoring the shallow water habitat quality and function of the previously constructed Hole-in-the-Rock backwater near river mile 706.0, approximately five miles north of Macy on the Omaha Reservation in Thurston County, Neb.
  • Release plan announced for Jamestown and Pipestem Reservoirs

    Snowmelt inflow is expected to begin at Jamestown and Pipestem Reservoirs in the next week. Combined releases from the reservoirs are currently expected to stay below 1200 cubic feet per second (cfs) with snowpack conditions being compared to 2001. Significant additional rainfall or snow may necessitate higher release levels.
  • Weather alters schedule; spillway flow test scheduled at Gavins Point Dam April 16

    The spillway flow test at Gavins Point Dam, originally scheduled for April 10, 2013, is rescheduled due to inclement weather. The new test date is Tuesday, April 16, 2013.

  • Public reminded about risks of living behind levees, below dams

    Dry conditions throughout the Missouri River basin since last summer might lead some communities throughout the Missouri River basin to believe that the risk of flooding is nonexistent this year. The risk of flooding still remains even during a drought, particularly due to isolated thunderstorms in areas below Gavins Point Dam where the Corps does not have a way to regulate the runoff. Residents throughout the basin are reminded to remain vigilant even during this drought period.
  • Spillway flow test at Gavins Point Dam postponed due to inclement weather

    The spillway flow test which was scheduled for April 10 at Gavins Point Dam has been postponed due to inclement weather. The new test date is Tuesday April 16. The purpose of the test is to gain additional information on the current condition of the spillway after interim repairs have been made. The test is being conducted as part of the ongoing rehabilitation and repair of the damage from the Missouri River Flood of 2011.
  • Spillway flow test for repair and rehabilitation to be conducted at Gavins Point Dam

    As part of the ongoing rehabilitation and repair of the damage from the Missouri River Flood of 2011, the U.S. Army Corps of Engineers, Omaha District, will temporarily shift discharges out of Gavins Point Dam from the powerhouse to the spillway on Wednesday, April 10 to conduct a spillway flow test. The purpose of the test is to gain additional information on the current condition of the spillway.
  • Corps to initiate releases at Pipestem Reservoir

    Pipestem Reservoir will be initiating a water quality release of 25 cubic feet per second (cfs) on Tuesday, April 2. Pipestem Reservoir is currently at pool elevation 1442.6 feet with approximately 2 cfs inflow and outflow.Jamestown Reservoir is currently at pool elevation 1429.7 feet with approximately 0 cfs inflow and outflow.
  • Corps seeks public input on upgrade and expansion of a wastewater treatment facility, Fort Peck, Montana

    The U.S. Army Corps of Engineers is currently in the scoping phase of preparing an environmental assessment for the proposed upgrade and expansion of the wastewater treatment facility on federal property within the town of Fort Peck, Montana. The purpose of the proposed project is to meet increased wastewater treatment needs of a temporary population expansion as a result of potential pipeline work if TransCanada’s Keystone XL Pipeline Project is approved for construction.
