The U.S. Army Corps of Engineers, Little Rock District, is making further adjustments to spillway operations at Norfork Dam as water levels continue to rise due to recent heavy rainfall.
At 3:30 Wednesday afternoon, the remaining three spillway gates were opened, bringing the total to all twelve gates open half a foot. This increase will result in a spillway release of approximately 6,600 cubic feet per second (c.f.s). The total water release, including hydropower operations, will be approximately 12,000 c.f.s.
Earlier Wednesday afternoon, the other nine gates were opened at half a foot releasing approximately of 4,972 c.f.s.
This release will continue until the flood pool crests and recedes to elevation 579 feet, in accordance with the established water control plan. The top of the flood pool on Norfork Lake is elevation 580 feet. The flood pool is currently at 579.61 feet and rising.
The highest recorded pool level at Norfork Dam occurred on April 11, 2008, at elevation 581.01 feet. The second-highest level was recorded on May 2, 2008, at elevation 580.9 feet.
Local emergency management officials downstream have been notified and are actively coordinating with their communities to ensure safety measures are in place. The Corps says public safety remains their highest priority, and they urge residents in affected areas to remain vigilant and follow guidance from local officials.
The U.S. Army Corps of Engineers will continue to closely monitor conditions and adjust operations as necessary. Further updates will be provided as circumstances evolve.
