Giant salvinia taking over Natchitoches Parish lake
Black Lake in Natchitoches Parish, once popular with anglers, is being overtaken by giant salvinia. In spots, it looks more like a field than a lake. It's even hard to tell where the land ends and water begins. Louisiana WildLife & Fisheries uses biological, chemical and physical measures to try to control the vegetation. One reason the overgrowth is worse this year is the lack of winter we had.
