State Installs Filtering System At Grand Lake St. Marys To Fight Algae Blooms

Jun 2, 2016


The Ohio Department of Natural Resources says toxic algae blooms at Grand Lake St. Marys in western Ohio are getting better.

Officials say a filtering system has helped reduce the blooms created by phosphorus runoff from nearby farmland. Artificial wetlands are being created to help strain the runoff from streams that empty into the lake. Signs have been posted warning people to not swim in the lake. Grand Lake St. Marys is Ohio's largest inland lake.
