ALERT FROM HARBORMASTER (June 2025): Attention boaters transiting the South River. This recent survey shows significant shoaling at the entrance into the South River, the shoaling as depicted on the survey starts at the entrance into the South River; near Green buoy #9. The shoaling continues towards South River buoy Red #2. This area was last dredged in 2019. However, significant shoaling has returned. The Towns of Marshfield and Scituate are working with federal agencies and state delegations to seek the needed funding to assist with this hazard to navigation. Mariners should use extreme caution when transiting this area and avoid transiting within 2 hours either side of the low tide. Larger drafted vessels may need additional tide to safely pass.

SHELLFISHING: The shellfish beds in both the North and South Rivers are now closed for the season. They are typically open from November 1 to May 31st.

Another Mary — Mary Duane Williams — ran Mary’s Boat Livery on this site from 1948 to 1986. Then Mary’s daughter Jane Duffy and her husband John took over the business. Roht Marine purchased the property in 2012.

This land is within the region of the Massachusett (or Massachuseuk). To learn more about local Native American tribes, we encourage you to interact with their members. The Mattakeeset band of the Massachusett, and the Massachusett tribe at Ponkapoag, both share information on their websites.

Habitats and Wildlife

Watch for the occasional harbor seal in the water. Bald eagles nest nearby, so you may see adult or young eagles. Also watch for the peregrine falcons, which sometimes chase terns.

The North River rises from marshes and springs in Weymouth, Rockland and Hanson. It is approximately 10 miles in length, with its source at the confluence of the Indian Head River (Hanover) and Herring Brook (Pembroke). From there it flows through the towns of Hanover, Pembroke, Marshfield, Norwell, and Scituate to the Atlantic Ocean between Third and Fourth Cliffs, draining approximately 59,000 acres along the way.
