How Healthy is Your Water?

Marks Cove in Wareham is part of the extensive Wareham River system, located in the outer Wareham River by the river’s mouth. The health of Marks Cove is fair, mirroring that of the entire Wareham River system. The nearby Weweantic River influences the health of Marks Cove because tides move water and nitrogen pollution between the two rivers. Improvements to the Wareham and Weweantic rivers will also help conditions in Marks Cove.
