Watershed Area Information

The Harraseeket River is a tidal embayment in South Freeport that receives water from several small brooks with their origins in Freeport and Brunswick.  Frost Gully and Mill Stream converge near Mast Landing, and Kelsey Brook empties into the Harraseeket from the northeast.  The Harraseeket, along with the Royal River estuary and Maquoit and Middle Bays, was designated as a Focus Area of Statewide Ecological Significance by Maine IFW due to its diverse habitat that supports a broad array of fish and wildlife. The Harraseeket contains contiguous tidal marsh along Frost Gully, and fringing marsh lines adjacent shores.  Several of the Harraseeket’s freshwater streams support sea-run rainbow smelt and other migratory fish, and the extensive mudflats support shellfish, waterfowl, and wading birds. Multiple protected lands provide public access to the Harraseeket including Winslow Park, Wolfe’s Neck State Park, and the Mast Landing Sanctuary.
