The Future of Dams
Helping New England Communities Use Science to Make Decisions about Dams

Hydropower is a major source of renewable energy in New England with more than 50 dams scheduled for relicensing in the next decade. However, dams can have adverse effects on coastal ecosystems and economies. They provide recreational and water supply benefits for many communities, but some pose safety risks due to old age and poor condition.
The Future of Dams Project, supported in part by a $6 million, 4-year NSF EPSCoR grant, is a stakeholder-engaged, solutions-focused, interdisciplinary NEST research initiative focused on the future of dams.
Collaborators in Maine, New Hampshire, and Rhode Island are empowering stakeholders to make complex decisions about dams by combining the best available science with diverse forms of community engagement.

Using dams in New England as a model system, collaborators are examining the economic, technological, ecological, social, and political trade-offs associated with different kinds of decisions about dams: for example, increasing power production at existing hydropower dams, installing new power production technology at non-power dams, maintaining existing but non-power dams for recreation or habitat, or removing dams to restore diadromous fisheries or address safety concerns.
This approach to problem solving is dependent upon – and benefits from – the local knowledge and know-how of diverse stakeholders representing government, business and industry, and non-governmental organizations.

Dams represent a literal and figurative nexus: a juxtaposition of infrastructure and freshwater ecosystems; an icon of technological innovation, economic prosperity, and cultural identity; a source of clean energy, opportunity for recreation, and threat to biodiversity.
