Corps to begin spillway releases on Saturday at Bull Shoals Dam

The U.S. Army Corps of Engineers Little Rock District has announced it will begin spillway releases from Bull Shoals Dam on Saturday to evacuate stored flood water.

The Corps will open four of the dam’s 17 gates by one foot, releasing 3,500 cubic feet per second. Combined with the dam’s eight power generation turbines, the total release will be 27,000 cubic feet per second.
Starting Sunday, four more gates will be opened one-foot to increase the spillway releases for a total spillway and turbine release will equal 30,000 cubic feet per second and continue for a prolonged period of time, unless significant rainfall occurs downstream of the dam. A 30,000 cubic foot release is equivalent to 10 hydropower turbines at full power.

The Corps anticipates 4,000 cubic foot spillway release from Norfork Dam to begin about January 20. The spillway release in combination with the 6,000 cubic feet power turbine release will equal 10,000 cubic feet per second, or the equivalent of three hydropower turbines at full power.

While the Corps has made similar releases in the past, property owners downstream of Bull Shoals and Norfork lakes should made necessary preparations now for the higher release planned for next week by ensuring that docks are properly anchored and maintained and remove any temporary encroachments from the floodplain. Daily lake information can be obtained at www.swl-wc.usace.army.mil or the Corps’ mobile App which can be found in mobile App stores by searching for USACE Little Rock.”

Please let me know if you have any questions.
