Over 1,000 Dams

We have estimated that at least 200 of these dams can be defined as derelict or deadbeat dams. They serve no useful purpose.

Dam Screening Tool

The Vermont Dam Screening Tool provides an assessment of the ecological impact of dams to fish passage in the Vermont portion of the Lake Champlain basin. It is designed to assist watershed managers and aquatic biologists in their efforts to strategically reconnect fragmented aquatic habitats. All known dams in the basin were grouped into one of five tiers, based on 17 metrics related to aquatic connectivity, watershed condition, aquatic ecology, and stream size. The data presented in this map are not intended to be prescriptive, and therefore do not imply any decisions about which projects could move forward. Field work and direct knowledge of the landscape are essential to making good management decisions. The accuracy of information included in this assessment is necessarily imperfect, and therefore needs to be updated periodically. Some dams included in this map may have been previously removed, and breaches may mean some dams are no longer barriers. Information about natural barriers to aquatic connectivity may be incomplete. This work was completed by The Nature Conservancy with funding from the Lintilhac Foundation, the U.S. Fish and Wildlife Service, and the Vermont Natural Resources Council. Advisory committee members for this work included representatives from the following organizations: Vermont Natural Resources Council, Lintilhac Foundation, Vermont Department of Environmental Conservation, Vermont Department of Fish and Wildlife, and U.S. Fish and Wildlife Service.
