Muddy River Conservation Focus Area

The Muddy River is a relatively small, largely untouched drainage that drains into Merrymeeting Bay at Pleasant Point in Topsham. The river is surrounded by extensive freshwater tidal marsh, a rare ecosystem that provides habitat for a unique group of plants and animals.  Consequently, the river acts as an important pre-migration staging habitat for thousands of waterfowl and wading birds. While the river is relatively short, it provides excellent bird watching opportunities from small boats. The area also contains archaeological artifacts and evidence of use by Native Americans.
