Helicopters are expected to hover over Lake Bistineau next week starting on Monday to administer an aerial herbicide to treat giant salvinia, according to the Louisiana Department of Wildlife and Fisheries.
But recreational activities will not be restricted on the lake, and LDWF personnel will be on hand to ensure boaters stay away from areas being sprayed.
Designated spray areas include Catfish Pond between Fairview Point and the mouth of Little Red Chute Bayou, according to a news release.
Results may be delayed because of cooler temperatures in the forecast, but the effectiveness of the herbicide will not be impacted. It could take up to three weeks for the plants to sink completely, the release states.
