The St. Marys Riverkeeper 's important role

The St. Marys River is 130-miles long, winding through four counties in two states. That includes more than 60,000 residents who depend on the health of the river for tourism, recreation, commercial fishing, and safe drinking water. Wildlife and plant ecosystems rely on the continued cleanliness of the watershed, including 3,000 miles of streams and tributaries. To all individuals, families and businesses who care about the local and global environment, and specifically clean water, please support SMRK. With your help, the St. Marys River will remain healthy and beautiful.

Celebrate the St. Marys River and 50 years of the Clean Water Act.

Join St. Marys Riverkeeper all October long for paddle trips, bike rides, brewery events, and our annual Big Splash Gala!

Our extensive Citizen Science water testing program is a powerful resource to protect our wonderful river.
Tracking water quality is a quantifiable tool that can either reassure us that the water is good or confirm that there is a problem and thus lead us upriver to find it.
