Colorado River

The Colorado River region of California is home to the Imperial Valley, the Coachella Valley, and the Palo Verde and Bard Valleys. This region is sometimes referred to as the “Winter Salad Bowl”, as the mild winters, good soil, and reliable water from the Colorado River allow a wide range of crops year-round, including grapes, dates, citrus, vegetables of all kinds, and numerous field crops as well as livestock. The Salton Sea is California’s largest inland lake and provides critical habitat for migratory birds in the Pacific Flyway.
