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 has improved to good in recent years. 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 continue to help improve conditions in Marks Cove.
