Hot weather, algae kills fish at Ohio lake

ST. MARYS, Ohio (AP) — High temperatures have contributed to the growth of toxic blue-green algae that has killed scores of fish in Ohio’s largest inland lake.

Area residents and Ohio parks officials found several hundred dead fish floating in the shoreline channels of Grand Lake St. Marys in western Ohio last weekend.

Fish kills are an annual summertime occurrence at the shallow, 13,000-acre lake when decomposing algae rob the water of oxygen and suffocate them. It grows thick from feeding on phosphorus from manure and fertilizers that wash from nearby farm fields.

Milt Miller, manager of the Grand Lake St. Marys Restoration Commission, tells The Columbus Dispatch ( ) that the recent hot days and calm lake with no wind contributed to the algae growth.

The state has spent millions trying to fight algae there.
