The U.S. Army Corps of Engineers outlined new plans Wednesday to manage Lake Okeechobee (Oh-key-CHOE-bee) and improve environmental conditions on South Florida’s signature inland body of water. The new plan will guide when and where to send lake water and is expected to go into effect late next year when repairs are finished to the Herbert Hoover Dike. Environmental groups praised the corps’ efforts to balance the different demands on the lake. Others feared it would release too much water into the St. Lucie Estuary, which has battled blue-green algae that has killed seagrass and fish.
