Saline Lake in Louisiana will be drawn down for giant salvinia control.
The Louisiana Department of Wildlife and Fisheries is also using the drawdown of the lake in Natchitoches and Winn parishes for organic reduction and fish habitat improvement.
Many Louisiana lakes face the same problems as Lake Columbia and Lake Erling in South Arkansas when it comes to the control of giant salvinia.
The Saline Lake drawdown is designed to stop expansion of salvinia as summertime temperatures promote maximum growth.
The water control structure is scheduled to be opened on June 1, and the lake should dewater at a rate of 4 inches per day. The water level will be lowered to a maximum drawdown level of 8 feet below normal pool stage, depending on the Red River Pool 3 water level. The Saline Lake control gates are scheduled for closure on October 1, to allow the lake to refill for fall, winter and early-spring recreational activities.
During the drawdown, an estimated 2,500-3,000 acres of water will remain in the lake.
The commission says the action is a necessary component of LDWF’s integrated management plan to control overabundant aquatic vegetation growth and to improve access for recreational activities.
