"Irrigation supports water intensive crops such as alfalfa, corn, and cotton, which have replaced many dryland crops"(Mayda 365).
Because of the unreliable precipitation, the Great Plains have used different methods to stabilizing water access. The Rocky Mountain transmountaint diversion has been a successful water project for the Great plains. Another method is the access to the Ogalala Aquifer water.
"Irrigation in the United States accounts for the agricultural viability of 26.8 percent of all land on farms and 64.8 percent of the nations total harvested cropland. West of the 100th meridian, 55 percent of all harvested cropland has been irrigated since the 1980s." (Mayda 365).
In the United States, large agricultural areas are where irrigation in common. These agricultural areas are the Mississippi River Valley of Arkansas, the Columbia Plateau, the Snake River Valley, the High Plains, and Coachella, and Imperial valleys of California (Mayda 364).
Coachella Farmland in California
"The 123-mile Coachella Canal and its underground water delivery system, managed by CVWD and used to irrigate nearly 60,000 acres of farmland, continues to attract irrigation specialists from throughout the world,
more than a half century after it was built"( http://www.cvwd.org).
