Excerpts: This bulletin is intended to give a description and review of the best features of the delivery of water to irrigators as disclosed by practice in the irrigated sections of the United States. It is not a complete treatment of the subject, because nearly every canal presents interesting points of difference from other canals, and the data on which it is based come from but forty or fifty systems. However, the systems from which information has been drawn are among the best managed in this country, and they at least show the best typical practice in this important branch of canal management. More of the systems selected for description are located in California than in any other State. This is because it has been possible to gather data about more systems in California than in any of the other States, and not necessarily because more can be learned from California practice than from practice elsewhere. In addition to the 11 California canals whose delivery systems are described, North Poudre, Larimer County, Consolidated Home Supply, and Rockyford canals, in Colorado; Wheatland Canal, in Wyoming; the Farmers' Canal, in Montana; Upper, South Jordan, Utah and Salt Lake, Davis and Weber Counties, and Bear River canals, in Utah; Nampa-Meridian Irrigation District Canal, in Idaho; Sunnyside Canal, in Washington; two small canals in Hood River Valley, in Oregon; Truckee-Carson irrigation project, in Nevada; Tempe Canal, in Arizona; and Northern and Pecos canals, in New Mexico, are included.
