Colorado River Basin Map
Redesigned in 2017
Redesigned in 2017, this beautiful map depicts the seven Western states that share the Colorado River with Mexico. The Colorado River supplies water to nearly 40 million people and in Arizona, California, Colorado, Nevada, New Mexico, Utah, Wyoming and the country of Mexico. Text on this beautiful, 24×36-inch map, which is suitable for framing, explains the river’s apportionment, history and the need to adapt its management for urban growth and expected climate change impacts.
The map features rivers, dams, water projects, major cities, Indian reservations, irrigated areas, basin boundaries, and national parks and monuments. The Colorado River Basin Map is complemented by the Layperson’s Guide to the Colorado River, which describes the history of the river, division of its water and current issues.
