• River Continuity

    Safe and stable stream crossings can accommodate wildlife and protect stream health while reducing expensive erosion and structural damage. The Division of Ecological Restoration’s River Continuity works to reduce impediments to movement of fish, wildlife and other aquatic life that require instream passage.

  • River Restoration

    The Division of Ecological Restoration’s restoration staff collaborates with dam owners, federal, state, local and nonprofit partners to facilitate, promote, and implement river and stream restoration in Massachusetts. The restoration staff focuses on restoring rivers and streams by removing unsafe or obsolete dams and obstructions to reconnect natural and cultural river communities.

  • Low Flow Inventory

    Most small streams and many segments of larger rivers are not routinely monitored in the state of Massachusetts for major changes in patterns of streamflow. However, some rivers experience extreme amounts of dewatering, particularly during stressful summer and fall months when streamflow is naturally lowest and human water use is greatest.

  • Anadromous Fish

    Anadromous fish live in the sea but must enter fresh water rivers and streams to spawn. Massachusetts coastal systems support 16 species of anadromous fish. Species such as the rainbow smelt, American shad and river herring (alewives and blueback herring) play an important role in the recreational and commercial fisheries, therefore, program efforts tend to concentrate on these four.
