Map of American Dams Removed Since 1912

While dams can benefit society, they also cause considerable damage to rivers. Dams have depleted fisheries, degraded river ecosystems and changed recreational opportunities on almost every river in our nation.

Today many dams that were once at the epicenter of community livelihood are now old, unsafe or no longer fulfilling their intended goals. Learn how we work to remove these dams and restore our rivers to their natural free flow.

We have created a current inventory of all dam removal projects, and this map is a graphical representation of our many years of research. It includes both projects we have led ourselves, and projects of others.

A narrative list of some of the dams removed from 1999 to 2020 can be found here.

Our database of removed dams can be found at Database information can be used by anyone if the following quote is included:

We want this map to be a great tool, so if you have any information to update any project (or add a missing project), let us know.
