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.
