U.S. Army Corps of Engineers today announced plans to replace Canyon Dam’s floodgate and warned stakeholders of lower release rates in the months ahead.
Workers with the Tennessee Valley Authority (TVA) will work on the outlet from Dec. 5 through April 15, 2023.
Flows will be shut off when workers are inside the conduit.
The public is advised to expect flows to be turned off for 10 hours then turned back on for 14 hours to allow for catch-up releases.
“This strategy will minimize stream-flow disruptions and allow needed flood-gate replacement work to be accomplished in a safe, timely and cost-effective manner,” USACE said in a statement released today.
