Returning to the Big Picture

The Columbia River Basin’s watershed is home to a set of very complex ecosystems. As we learn more about these ecosystems and our influence on them, sensitivity and concern toward maintaining a healthy environment have risen. While our knowledge is still limited, experience and research teach us more each day.

This overview of the watershed and its ecosystems provides a foundation for building on this awareness by examining 1) how hydroelectric projects can affect a river, and 2) enhancement and mitigation efforts being made to address those impacts.
