189 acres of Norwell Conservation Land with an extensive trail system around the north, east, and west sides of the 60-acre pond.
There are canoe/kayak launches at both the Jacobs Lane and Duncan Drive entrances. There is a fishing dock at Jacobs Lane. Other fishing locations include the Cliff Prentiss Bridge near Duncan Drive, the island within the pond, and the water’s edge along Main Street.
No motors (gas or electric) are permitted on the pond. Winter activities here include cross country skiing, ice skiing, ice boating, and ice fishing.
Jacobs Pond was created in 1723 when Third Herring Brook was dammed, at Main Street, to create power for a grist mill and later a sawmill. The sawmill burned down in 1920. Also at this site, there was a brick manufacturing facility (1680-1830).
The area itself is known as Assinippi. The name, given by early native inhabitants, means “rocky water.” The pond was originally called Snapper (or Snapper) Pond. “Snapper/Snappet” was a play on the word “Assinippi.” Later it was named for the Jacobs family, whose farmhouse, barn, and hay fields are located across Jacobs Lane (now overseen by Norwell’s Conservation and Historic Commissions).
The headwaters for Third Herring Brook are located north of the pond, in the southern portion of Valley Swamp. Third Herring Brook exits the pond from its sound end, at the dam. (Watch for a fish ladder here in the future!) The brook forms the border between Norwell and Hanover, and flows into the North River downstream of the old stone bridge on Washington Street.
Trail access from Jacobs Lane, from Prospect Street, and via the Cliff Prentiss Bridge off Duncan Drive.
From the Jacobs Lane parking area, a dirt road leads to the pond and the trails. The trails are mostly dirt, but there are also some boardwalks that traverse wetlands. Along the western side of the pond, the trail follows an esker ridge.
Habitats and Wildlife
The pond and conservation area provide habitat for small mammals, fish, turtles, frogs and birds. Common fish found here include chain pickerel, yellow perch, calico bass, and largemouth bass. Listen and watch for toads, turtles, and a variety of frogs (bullfrogs, green frogs, pickerel frogs). You may see snapping turtles and northern water snakes too.
The forest surrounding the pond is made up primarily of pine and oak, but you’ll also find beech, hemlock, maple, and a few clusters of mountain laurel. In the wetlands, look for ferns and skunk cabbage.
