In Hanover, Norwell and Scituate: Four dams block fish passage in these towns. To learn more about the impacts of the dams, the North and South Rivers Watershed Association (NWRWA) is looking for volunteers to read stream gauges. NRSWA is now working on restoration of Third Herring Brook in Norwell and Hanover. In addition, they hope to restore herring passage to First Herring Brook, which is blocked by Scituate’s Town Reservoir Dam. NSRWA is working with Scituate to find a way to restore herring while also meeting water supply needs.
Of particular concern: a small private dam on Third Herring Brook.
