Nissitissit River Wildlife Management Area borders Massachusetts and New Hampshire. Some of the trails at this hotspot cross through both states. If you keep careful records of birds by state, be aware of the location of the state border and use the appropriate hotspots or personal locations.

In the Nipmuc language, Nissitissit means “between two brooks.” The Nissitissit River WMA contains over 600 acres of forests and wetlands that surround and protect the river and several of its tributaries. The river is widely recognized for its ecological, recreational, cultural, and aesthetic value. Upstream near the New Hampshire border, the river is narrow with high banks and lots of large woody debris—a feature beneficial to aquatic life. Further downstream as Sucker Brook and then Mine Brook flow in, the Nissitissit becomes wider and rockier. In 2015, MassWildlife removed the Millie Turner Dam and reinforced areas of eroding streambank to restore trout and freshwater mussel habitat. Visitors can explore the WMA by way of several unmarked paths.

Two parking areas are available off Prescott Street, one parking area is available off North Street, and an additional parking area is on Brookline Street. The southernmost parcel can be accessed by parking on Hollis Street at the site of the Turner Dam removal.
