The Jackson-Bienville Wildlife Management Area is getting smaller.
The Louisiana Department of Wildlife and Fisheries says its latest lease with the Weyerhaeuser Company will keep about 25,000 acres open to public recreation such as hunting, fishing, hiking, birding and nature photography.
It says about 7,000 acres will be closed to the public. That's nearly 22 percent of the original size.
The property is in Jackson, Bienville and Lincoln parishes. The department has managed it since 1951.
In an effort to control aquatic vegetation, the water control structure on Lake Bistineau near Minden will be opened Aug. 8 for a lake drawdown.
As a result of mild winter temperatures, experts say giant salvinia has expanded beyond the control capacity of herbicide applications and salvinia weevils. Louisiana Department of Wildlife and Fisheries survey estimates show giant salvinia coverage to be in excess of 2,000 acres.
The lake will be lowered seven feet below pool stage and will remain there until Jan. 31, 2013.
