When the first dam was founded by Theodore Roosevelt,
America's first great conservationist President, the way dams change river
systems and their wildlife was not well understood. Today, after decades
of study, we know a great deal more about these impacts. With that knowledge
comes a greater responsibility and trust.

The river systems in which dams operate are home to thousands
of species, millions of trees, priceless mountains, plains, canyons, and
deserts unlike any other in the world. Dams help preserve wetlands, add
to instream flows, preventing groundwater contamination, control water
salinity, control sources of pollution, and conserve and enhance fish and
wildlife habitats. All of these environmental obligations are vital to
the environment. All these must be addressed before constructing a dam
