Marshfield’s Wharf Creek Conservation area offers two trails through an open woodland with old stone walls and views of Wharf Creek and the Green Harbor River. Excellent for birders!

Features

Also known as Estes Woods, this property features a number of old stone walls within a relatively open woodland. The views Wharf Creek and the Green Harbor River are quite nice! A portion of this property was acquired by the town in 1978, with more to follow.

Some history: Efforts to improve the Green Harbor River’s navigability date back at least to Marshfield’s Colonial era. In 1633, a canal was dug to better connect the river to Duxbury Bay. In 1636, this canal was widened and deepened per order of the court.

The original mouth of the Green Harbor River, which was located on the Marshfield/Duxbury line, more than a half mile south of the present mouth, was closed by a storm in 1806. The present mouth opened in 1810, probably via the combined effects of nature and manpower.

According to Joseph C. Hagar’s Marshfield, 70’40” W, 42’5” N: The Autobiography of a Pilgrim Town, in 1806, a group of Marshfield landowners successfully petitioned the court for permission to dig a more direct canal from Green Harbor to Duxbury Bay. Known today as the Cut River, this canal flowed through the meadows behind Green Harbor Beach, into the marshes beyond Marshfield’s Canal Street into Duxbury Bay. But soon after the canal was complete, a November storm closed off its mouth completely.

An even more direct outlet was cut in 1810 – and remains to this day. While prior attempts to improve the river’s navigability had been permitted — or even decreed — by the court, this was a case of townspeople taking matters into their own hands. Hagar’s writes, “This labor was done under cover of night and about forty men were engaged in the undertaking.” (This was not an uncommon practice – similar attempts were made to improve the outlet for the North River.)

By eliminating the narrow last leg of the river, the 1810 cut dramatically increased the incoming tidal flow to the Green Harbor River. This was a boon to local fishermen, as it improved the harbor’s navigability. However the owners of farms bordering the river saw things differently. The increase in both the volume and the frequency of saltwater flooding to their lands was a big problem, as crops don’t like salt water.

So in 1871, a group of farmers petitioned the court to construct a dike, or tide gate, that would block the flow of saltwater upstream, and create more arable land. The dike was constructed in 1872, with the condition that “Should shoaling take place above the level of mean low water in the channel in consequence of dike construction, it was to be removed by the Marsh proprietors.” Shoaling did occur, and thus began the “Brant Rock Dike Feud.” Read all about it on our blog.

This land is within the region of the Wampanoag. To learn more about local Native American tribes, we encourage you to interact with their members. The Mashpee Wampanoag and the Herring Pond Wampanoag share information on their websites.

Trail Description

There are two trails on this property. One begins at Dyke Road, across the street from Green Harbor Marina, and leads about 1/3 mile through the woods to the Green Harbor River. There is a small stream crossing at the beginning of the trail, and then it leads into a thicket of trees and underbrush before emerging at the edge of the river.

A second trail extends for about 0.4 mile from Calypso Lane to Wharf Creek. The trailhead is located between #57 and #63 Calypso Lane. Follow the row of trees to the trailhead, where there is a gate and a trail sign. Please be mindful of private property! A wide cart path enters the woods, crosses a small stream, and leads past a power easement, before narrowing and continuing through the woods to the edge of the marsh and Wharf Creek.

Note: While the two trails used to connect, they currently do not. The Dyke Road trail is narrow but flat. The Calypso Lane trail is also flat, and somewhat wider. Some sections of the trails are wet and/or overgrown.

Habitats and Wildlife

Forests of oak, elm, maple, and silver birch, with plenty of fern, greenbrier, native chokeberry and invasive bittersweet. Watch out for poison ivy! The thicket along the Dyke Road trail is an ideal place to observe birds. In the spring, it tends to be very popular among warblers. There are also some wetlands on this property. Once you arrive at Wharf Creek and/or the Green Harbor River, watch for the osprey that nest up above (look for the nests on top of the utility poles). You may also spot a tern.

This property is located where Wharf Creek flows into the Green Harbor River. The Green Harbor River finds its source in springs and ponds in Duxbury. It twists and turns through Marshfield via a large cranberry bog complex, the Green Harbor Golf Club, the Daniel Webster Wildlife Sanctuary, property owned by the Marshfield Municipal Airport, and Peter Igo Park. Just downstream of the Dyke Road bridge (and dike) it flows into the Atlantic Ocean at Green Harbor.
