Herring River Tidal Restoration Project

The Herring River Restoration Project in Massachusetts will replace the restrictive dike at the mouth of the river with a bridge that will allow tidal water to flow freely between the river and Wellfleet Harbor. This will restore the biodiverse, productive, estuary that existed pre-dike construction. This will improve water quality, restore fish passage and important fish populations to the river, restore marsh vegetation, help store carbon dioxide in the newly created wetlands, and provide new recreational opportunities along the river. By restoring tidal range, this project will lead to higher sediment transport and deposition, increasing wetland plant cover, reducing inland erosion, and increasing storm surge protection for the floodplain.
