Kennebunk River Watershed
Brimstone Pond lies north of Bimstone Road. The pond is 6.6 acres in area and is bordered by open fields, forest, and marsh.
Davis Pond is 4 acres in size and is mostly marsh during the dry season. A thin strip of forest buffer stands between the pond and Limerick Road to the west. The southern shore is bordered completely by open fields with one home.
Duck Brook runs out of a forested area west of I-95 between the Dutch Elms Golf Course and the Mildred L Day Middle School. It flows past a large farm before crossing under the highway, and runs for approximately 1.25 miles through forest before joining the Kennebunk River.
Goff Mill Brook runs for approximately 7 miles along the extent of Arundelís eastern border with Kennebunkport, paralleling the Boston & Maine Rail Line until the tracks cross Log Cabin Road and turn west. There the brook continues south and encounters little development as it passes through a half mile stretch of forest. It emerges in the backyards of several residences along Sinnott Road, passes a 100+ unit subdivision, and converges with the Kennebunk River near the Cape Arundel Golf Course.
The Arundel Swamp sits between Sinnott Road and River Road. It is an undeveloped area approximately .5 square miles in size. It feeds a small brook that runs south to the Kennebunk River.
The Kennebunk River forms Arundelís western boundary with the town of Kennebunk. It enters from Lyman and runs for approximately 12 miles before leaving Arundel on its way to the Atlantic Ocean. The banks of the Kennebunk River are bordered by farms and open fields from the Lyman border to I-95. From the interstate the river runs through forest and marsh, past many homes, and several subdivisions.
