Logan Martin Dam, Alabama

Alabama Power Company

The Coosa River fishery below the Logan Martin Powerhouse is considered excellent for hybrid striped bass and catfish. Seasonally, spotted and largemouth bass also inhabit the tailrace .Low levels of D.O. in the leakage water coming from the dam were one probable cause of recurring fish kills. Alabama Power opted to install an ECO2 SuperOxygenation cone below the Logan Martin Dam and about 30 miles east of Birmingham to solve the fish kill problem.

The ECO2 Speece cone is 9 feet in diameter at the bottom and treats approximately 14 MGD. The D.O. at the discharge is 51 mg/l in 86F water. The system dissolves about 6,000 pounds of oxygen per day and achieves approximately 90% oxygen absorption.
