A temporary drawdown of Black and Clear Lake (Natchitoches Parish) has been scheduled by the Louisiana Department of Wildlife & Fisheries. Supported by resolution of the Northwest Louisiana Game and Fish Preserve Commission, this low water period is intended to reduce acreage of giant salvinia in areas where applying herbicides is not possible, while minimizing cypress and buttonbush growth, and allowing for refill by waterfowl season. Without a drawdown, these small areas of giant salvinia typically expand in coverage going into the fall and into the following growing season.

The water control structure is scheduled to open on July 14, 2025, and the lake should dewater at a rate of three to six inches per day, depending on the Red River Pool Three water level. The water level will be lowered to a maximum drawdown level of approximately four feet below normal pool stage to a target level of 95.0 MSL. Target exposure time at 95.0 MSL is one month or longer.

During the drawdown, an estimated 7,000-8,000 acres of water will remain for access in open areas of Black and Clear Lake. Boaters may still access Black and Clear Lake from either Black Lake Haven and Campground or Chandler’s Camp ramps, located on the North side of the Hwy 9 Bridge. Caution is also advised when on the water as numerous obstructions that are normally not seen are present or just below water surface.

An annual cycle of high and low water fluctuation can provide ecosystem and fisheries benefits similar to a natural overflow lake system.

This action is in conformity with the current LDWF Black and Clear Lake Aquatic Vegetative Management Plan, and that plan can be viewed at:
