JONESVILLE, La. (AP) - The Louisiana Department of Wildlife and Fisheries has begun releasing water from Catahoula Lake to provide waterfowl habitat and as part of a management and research program to find ways to control trees in the lake.
A news release says that, if rain and runoff permit, the water level should fall from nearly 32 feet as of Friday to about 27.5 feet by June 30.
Catahoula Lake is in LaSalle Parish west of Jonesville.
It provides important wetland habitat for migrating waterfowl, shorebirds, and other wetland birds.
Scientists say leaving the water high all the time reduces productivity in wetland systems. They say it may also let swamp privet and water elm trees spread, displacing plants that waterfowl like to eat.
