New warning systems at Ocoee No. 3 and South Holston Dams

TVA recently installed automatic warning systems at two additional hydroelectric projects. New systems are now in place and operational at Ocoee No. 3 and South Holston.

These warning systems are necessary since reservoir operations for flood control, power generation, and other purposes can create hazardous conditions both upstream and downstream of dams.

“Visible and audible warning devices will be activated automatically prior to water-level changes in an effort to ensure public safety,” says TVA Senior Vice President of River Operations Janet Herrin. “When these sirens sound and strobe lights flash, boaters and other recreational users should move quickly to safe areas.”

TVA has installed signs, horns, and strobe lights at the Ocoee No. 3 diversion dam and two miles downstream at the U.S. Forest Service’s Whitewater Center. That downstream location also features a pre-recorded voice warning that changes with the estimated amount of time before rising water reaches that area.

At South Holston, signs, horns, and strobe lights have been installed on the powerhouse structure and downstream at the weir.

Automatic safety warning systems also are in place at these dams: Apalachia, Chickamauga, Fort Loudoun, Great Falls, Kentucky, Nickajack, Norris, Tims Ford, Watts Bar, and Wheeler.
