Dams in Every District: Challenges, Opportunities, and What’s Ahead

The Environmental and Energy Study Institute (EESI) and American Rivers held a briefing to learn about the state of dam infrastructure in the United States. Rivers across the United States are dotted with dams built for various purposes, from powering factories to irrigating croplands. In fact, there are more than 500,000 dams across the country. Of the dams in the National Inventory, 85 percent have outlived their expected lifespan and many are no longer serving a purpose. This presents a critical challenge for dam owners, municipalities, states, the federal government, and industry as they seek to ensure community safety.  This briefing discussed the options dam owners have to manage this infrastructure challenge, including dam removal, which is a common approach to dam safety and river restoration. Dam owners frequently seek help with removing their obsolete and unsafe structures, and dam removals are only completed with dam owner consent. To date, dam owners have worked with federal agencies and nonprofits to remove 2,119 dams, the majority of them in the last 25 years.  Panelists discussed the need to pay attention to dams as key infrastructure--including dams that provide carbon-free electricity to 30 million Americans--that has an impact in districts across the country. Bringing together perspectives from federal agencies, local leaders, and the hydropower industry, the briefing highlighted funding, programs, and projects that advance public safety through dam removal as well as river restoration.
