Culvert Survey Training

The Massachusetts Division of Ecological Restoration (DER) provides training on assessing culverts to determine if they are barriers for fish and wildlife.

Culvert Survey Training

The North Atlantic Aquatic Connectivity Collaborative (NAACC) is a network of individuals from universities, conservation organizations, and state and federal agencies. NAACC focuses on reducing the adverse impacts of undersized culverts (road stream crossings). Undersized culverts can be damaged during storm events. They can also create a barrier for fish and wildlife.

DER has been key players in NAACC since the partnership’s began. There are more than 30,000 culverts in Massachusetts. Volunteers survey these culverts to help find the location and extent of barriers. Surveys are conducted following the North Atlantic Aquatic Connectivity Collaborative (NAACC) protocols.

Become certified as a lead observer or coordinator

To be certified as a lead observer or coordinator, a person must satisfy three training components:

  • Protocol training either in-person (3 hours) or online. Everyone must go online to pass the training questions.
  • In-person field training (4-6 hours)
  • Shadowing an experienced observer at 20 sites

If you are interested in starting a survey in your community and wish to receive training, please contact: Jacob Lehan, Stream Crossing Assessment Coordinator, 413-579-3016 or
