Salmon Falls River Watershed
Grant Brook originates in a marsh area near Beech Ridge Road. It flows for a mile through woods and marsh and then leaves North Berwick.
Togue Brook flows out of the northern end of Maple Swamp and runs north for a mile through forest until it leaves North Berwick.
The Little River flows into North Berwick from Lebanon, near Lebanon Road, where it passes a small farm and crosses under Little River Road. It runs for approximately 1.25 miles before forming several dramatic oxbows and passing into Berwick.
Great Works River WatershedMaple Swamp is an area of wooded and emergent wetland sitting on the North Berwick border with Berwick west of Beech Ridge Road. Maple Swamp Brook drains out of the southern end of Maple Swamp in an undeveloped forest area west of Beech Ridge Road. It crosses Governor Goodwin Road and passes several small farms and a few homes. The brook then passes through a culvert on Beech Ridge Road and pools behind a dam at Cider Mill Pond Road. After passing the dam, Maple Swamp Brook passes under Somersworth Road and crosses a large farm field. It then travels for a half mile through forest until converging with Frost Brook.
Abbott Brook flows out of a wetland near the intersection of Beech Ridge and Governor Goodwin Road. It flows south past the Noble High School and crosses large farm on Somersworth Road. The brook then backs up at a beaver dam west of Buffum Road. A half mile further downstream Abbott Brook converges with Maple Swamp Brook. Frost Brook begins at this convergence and flows for a half mile until it meets the Boston and Maine Railroad tracks. After passing under the tracks the brook converges with Beaver Dam Brook flowing in from Berwick. The two brooks combine to become Hussey Brook, which runs for a short distance before passing under a bridge on Elm Street, crossing the power line right of way and entering South Berwick.
Estes Brook runs out of a wooded area a mile south of Bauneg Beg Mountain, between Turkey Road and Oak Woods Road. The brook runs past a few homes and small farms and flows under Turkey Road. It continues to meander for a quarter mile and then joins the Neoutaquet River. This river begins near Lebanon Road and gathers water from several small streams as it flows southeast past homes, farms, and a small junk yard on Lebanon Road. Estes Brook adds its waters just before the river enters a 2.25 mile stretch of forest that extends south to Governor Goodwin Road. Neoutaquet River passes under the road and then turns east, flowing parallel to Maple Street for a half mile. The river begins to widen as it crosses the power line right of way and then flows through the backyards of several homes and businesses on Lebanon Road. The banks of the river become increasingly urban as it flows into North Berwick center, where it passes a dam and then joins the Great Works River.
Perkins Brook crosses into North Berwick from Wells and flows for just a half mile before joining West Brook. West Brook flows into North Berwick from Wells right next to the Boston and Maine Railroad tracks. It is soon joined be Perkins Brook from the north and another small stream from the south. The brook widens as it backs up behind a small dam at the Pratt and Whitney manufacturing facility. West Brook crosses two small roads behind the facility and then flows into the Great Works River.
The Great Works River forms most of North Berwick’s eastern border with Sanford. It flows past numerous homes along Morrills Mill Road and gathers water from a small stream before passing through a narrow bridge on Fox Farm Hill Road. The river meanders past a gravel pit and enters a large marsh area bisected by a power line right of way. It then begins to widen as it flows into Bauneg Beg Pond, a 180 acre body of water that lies across the North Berwick and Wells border. The shoreline of the pond is moderately built up with homes a few small roads right at the waters edge. At its outlet from the pond the Great Works River passes a small dam on Morrills Mill Road and continues south as several small streams and marshes add to its waters. The river forms a short stretch of rapids as it narrows and passes under a bridge on Boyle Road. It flows through mostly undeveloped terrain for three miles before encountering another dam on Staples Drive. Here the river forms a reservoir bordered by a large condominium complex with lawns right down to the shoreline. Passing the dam, the Great Works River twists and turns around a large farm on High Street and is then joined by West Brook at near the Pratt and Whitney facility. The river meets a large dam in the center of town and is joined by the Neoutaquet River a quarter mile downstream from the Wells Street bridge. As it leaves the highly developed town center the river begins to twist and turn again, flowing past the wastewater treatment lagoons on Eastern Avenue and passing into South Berwick.
