Grand Lake St. Marys lake tested for toxins from algae

The state is awaiting water quality test results to determine whether it needs to post additional advisories about potential hazards at Ohio's largest inland lake, which has been plagued by toxic algae in recent years.

Blue-green algae have hampered tourism near Grand Lake St. Marys in western Ohio. Algae growth was accelerated this year because of unseasonably warm winter and spring weather.
 
The algae blooms previously led to lake closures and swimming advisories because they can produce a nerve toxin that can sicken people. A spokeswoman for the Ohio Department of Natural Resources tells The Lima News water quality testing will help determine whether advisories or extra signage are necessary as summer kicks off.  
 
The manager of a restoration commission says the lake is open and ready for visitors.
