ST. MARYS — A nationally recognized science firm has whittled down potential solutions that could help Grand Lake St. Marys.
Battelle recently unveiled a comprehensive, draft report that details its recommendations to help restore the water quality of Grand Lake St. Marys as well as how to limit phosphorus from entering the body of water. Earlier this year, members of the Grand Lake Restoration Commission tabbed the firm to review the more than 70 of proposals it received regarding possible solutions to help the lake.
Battelle screened each of the 75 vendors and scored each to determine the feasibility of the solution. During the review process Battelle met with lake officials to determine strategies to help the lake. Those included: reduction of external loading by source reduction or treatment, reduction of internal loading by removal or inactivation of phosphorus already in the lake's sediment, aeration and circulation and algaecidal agents.
Some of the solutions included additional alum treatments to the lake and its tributaries, the continuation of dredging and rough fish removal as well as increasing aeration in open and closed lake channels.
