River of the Month Series

Each month during Arizona’s centennial year, the "River of the Month" series profiles a different river in celebration of the state’s precious natural resources. From the mighty Colorado to the smallest ephemeral streams, these waterways have supported Arizona’s people and places for thousands of years. With good stewardship and thoughtful planning, they will continue to flow into Arizona’s next 100 years.

The series is produced by Environmental Defense Fund, Sonoran Institute, Sierra Club, Grand Canyon Trust, and Western Resource Advocates.
