Herring Runs

Foundry Pond


Owned By: Town of Hingham

Pond, salt marsh and an abandoned quarry. In the spring, look for river herring swimming upstream at the fish ladder.


Foundry Pond was created when the Weir River was dammed in the late 1700s. The Hingham Malleable Iron Company (1840-1876) and Colonel Weston’s wool processing factory (until 1888) were both located here, but they each were destroyed by fire. Later, The Sportsmen’s Club acquired the property, and in time, sold it to the Town of Hingham.

Across Rockland Street, check out Amonte Meadows (3.3 acres), a small conservation parcel on the Weir River with grassy areas, wetlands, and a stand of Tupelo trees.

Trail Description

There is a very short trail at the Kilby Street entrance, where you can cross a small wooden bridge over the spillway and possibly get up-close views of migrating fish (in season). This entrance puts you almost directly on the dam itself, so it’s a very short walk to the water.

There is a longer trail from the Weir Street entrance that features 0.77 miles of woodland trails, both wide and narrow, that lead to Foundry Pond and where you can view the herring fish ladder.

Habitats and Wildlife

Both Native Americans and colonists used weirs to catch herring here, and that’s how the river got its name. The Weir River runs through Hingham, starting at Accord Pond and ending at the Weir River Estuary between Hingham and Hull. The herring run here is impacted by upstream water withdrawals that lower streamflow in the summer and fall when juvenile herring are migrating downstream. Like many fish ladders that were placed on old dams, this one is not ideal for fish passage.

Some of the fish that might be found at Foundry Pond include river herring, smelt, brown trout (stocked from Europe), brook trout, largemouth bass, red fin pickerel, bluegill, pumpkinseed sunfish and American eel.

The forest here is composed of pine, oak and cedar, plus some bittersweet and holly. There is also marshland, with plenty of cattails.

Deer hunting is permitted on this property from October 19 to November 28, but only with a Special Permit from the Hingham Conservation Commission.
