Natural resource officials say they have exceeded dredging goals this year for Ohio's largest inland, which has been plagued by toxic algae outbreaks.
The dredging is part of the state's plan to improve conditions at Grand Lake St. Marys, a 13,500-acre recreational lake in western Ohio. Other water quality initiatives include rough fish removal and installation of a treatment train. The Ohio Department Natural Resources says more than 302,000 cubic yards of sediment was removed from the lake this year, topping its goal of 300,000 cubic yards. The department and private groups also worked to remove more than 17,000 pounds of rough fish from the lake. Phosphorus from farm fertilizers and livestock manure ends up in runoff and has been blamed for feeding algae blooms at Grand Lake.
