The Colorado River Basin Layperson’s Guide introduces the river that sustains more than 40 million people and irrigates more than 4.5 million acres of farmland across the Southwest and parts of northern Mexico. The 28-page overview explains how the river’s water is shared and managed and covers the environmental, tribal, agricultural and recreational interests at stake.

The illustrated 24×36-inch map is frame-worthy for the office, educational for the classroom and decorative for the home. The map includes water projects, Indian reservations, irrigated lands, basin boundaries and national parks and monuments. 

Our Layperson’s Guide to the Colorado River Delta introduces the region’s environmental and agricultural significance and its diminishment resulting from the many upstream water diversions. It covers the U.S.-Mexican agreements to restore the once-rich wildlife habitat and sustain Mexicali Valley’s farm economy.
