CLAM Program

CLAM logo color

The Citizen Lake Awareness and Monitoring (CLAM) program, sponsored by the Ohio Lake Management Society (OLMS), provides an opportunity for Ohio citizens to take an active role in learning about aquatic ecology, lake and stream water quality, and watershed management.  CLAM also documents the water conditions in Ohio and offers excellent networking for people and local environmental organizations.
