Kennebunk River Watershed
Goff Mill Brook draws water from several marsh areas in Kennebunkport along its border with Arundel. The first is a forested wetland in the northern part of town near Proctor Road. The second is a wetland near the intersection of Goose Rocks Road and Moose Rocks Road. The third is a mix of emergent and forested wetland between Arundel Road and Mount Kineo Road. Goff Mill Brook eventually runs into Kennebunkport near the Cape Arundel Golf course, just before merging with the Kennebunk River.
The Kennebunk River flows along the border of Kennebunkport and Kennebunk. Development along this portion of the river is the continuous and includes dense residential areas, marinas, hotels, and the Cape Arundel Golf Course, which borders the river for about two thirds of a mile. The Kennebunk River meets the Atlantic Ocean on Goochs Beach.
Coastal Drainages: Biddeford Pool to the Kennebunk River
Little River crosses into Kennebunkport at the border with Biddeford, near Route 9. It flows for a mile past a few dozen houses before it transitions to tidal estuary and empties into the Atlantic Ocean by Timber Point. Beaver Pond is a 12 acre saltwater tidal marsh which flow into the estuary with the Little River.
Crow Swamp is an area of forested and emergent wetland near the intersection of Whitten Hill Road and Goose Rocks Road. There are a few homes and farms adjacent to the swamp. A small brook drains this area and flows southeast to join Smith Brook at Goose Rocks Beach.
Smith Brook drains a few scattered wetlands along Route 9. Several small streams come together from these areas and run south to join a tidal salt marsh behind Goose Rocks Beach. Smith Brook runs southwest along the barrier beach until it meets Batson River and forms a small delta that empties into the Atlantic Ocean.
Tyler Brook begins near the intersection of Beechwood Avenue and Old Cape Road. It runs for mile, through forest and freshwater marsh, until it begins to turn north and transition into brackish tidal marsh near Route 9. Here it crosses the road through a culvert and soon converges with Batson River.
Batson River originates in an area of forest north of Cole Benson Road. It flows south, crossing Cole Benson Road and Guinea Road. Still heading south, the river passes several farms and then flows through a culvert on Goose Rock Road. Crossing Arundel Road through another culvert, the river runs past a half mile of farm fields. At this point Batson River becomes brackish as tidal waters flow upstream from the Atlantic Ocean. Passing through the estuary, the river empties into The Gulf of Maine.
