Great River Hydro

A final plan is out to relicense three major hydropower dams on the Connecticut River between New Hampshire and Vermont – a big milestone in a years-long federal process.

New Hampshire will offer a new federal grant program to rehabilitate some of its dozens of so-called “high hazard” dams – ones that would threaten life and property if they failed.

The Federal Emergency Management Agency launched the program this year, giving New Hampshire close to half a million dollars to give to towns, nonprofits and dam owners.

A first-of-its-kind survey shows New Hampshire residents generally favor removing dams from local rivers.

Researchers from UNH asked 1,500 residents about whether they’d prefer to see a hypothetical dam removed, allowing for a free-flowing river, when presented with various alternatives.

They asked if residents would want dams to remain in place for hydro-electric generation or historic preservation, or to maintain property values or recreational opportunities.

Regulators are planning new efforts to keep the state’s rivers from running dry, and they’re taking public input on which rivers to study next.

The state’s instream flow studies will look at how much water runs through a river under different conditions – say, in drought – and at how animals, plants and people like to use that water.

Eversource has finished selling off its hydroelectric dams. This marks the end of New Hampshire's years-long electric restructuring process.

That effort, also known as deregulation, sought to lower rates and increase competition by separating power generation from distribution.

As part of restructuring, Eversource agreed in 2015 to sell its fossil fuel-fired power plants and hydro dams in New Hampshire.

Nature Conservancy

A major study of the Connecticut River shows how its flow and ecosystem has been altered by dozens of dams.

The nonprofit Nature Conservancy worked with the Army Corps of Engineers to try and reconstruct how the Connecticut River might flow if not for the more than 70 large dams in its watershed.

Right now, a group of hydroelectric dams on the Connecticut River are undergoing a once-in-a-generation process – a federal relicensing. NHPR’s Annie Ropeik went to the dams and talked with people who live, work and play nearby about what they hope might change.
