Abstract
Within the Great West of the present United States, there are three periods of irrigation history—the prehistoric, the pre-pioneer, and the modern. Considerable information is available concerning each of these periods. The Prehistoric Period.—Irrigation was practiced in the West before modern man took possession of America. Remnants of irrigation canals and structures in California, Arizona, New Mexico, Colorado, and Utah, bear witness to a dense population that throve under the irrigation ditch.
A significance statement is not available in the OpenAlex record.

Findings are not separately available in the OpenAlex metadata.
