Wilder Dam, the major hydropower dam influencing the Connecticut River in the Upper Valley, straddles the river between Lebanon and Hartford. The dam impounds (backs up) the river for 45 miles upstream, and receives drainage from a 3,375-square-mile watershed in New Hampshire and Vermont. Wilder’s three turbines have a combined generating capacity of 42 megawatts.

The New Hampshire-Vermont state line runs down the middle of Wilder Dam Reservoir. See Wilder Dam (Vermont) for hotspots on the reservoir in Vermont.
