News George’s Pond Tidal Restoration Project in Development (Dartmouth)

Currently there is a 90% reduction in the tidal range within Georges Pond, resulting in a loss of intertidal habitat and reduced water quality.

The current crossing and culverts at George’s Pond cause a 90% reduction in tidal range.

Over the last few years, DER has been providing technical support to the Massachusetts Department of Conservation and Recreation (DCR) to restore tidal flow within Georges Pond, a tidal estuary located in Demarest Lloyd State Park in Dartmouth. The pond discharges to Giles Creek, which conveys water to the Slocum River and eventually, Buzzards Bay. Currently, tidal water must flow over a relic stone crossing and through dual, four-foot diameter culverts beneath the park’s primary access road to the adjacent barrier beach. The combination of the relic crossing and culverts has caused a 90% reduction in the tidal range within Georges Pond, resulting in a loss of intertidal habitat and reduced water quality.

In 2014, DER contracted with Woods Hole Group, Inc. to develop a hydrodynamic model and various design alternatives to alleviate the muted tidal range. The design will require balancing the ecological needs of the site with public safety concerns and potential impacts to rare species. DCR has committed funding for design and permitting and has contracted with GZA GeoEnvironmental, Inc. to complete this work.
