Rancho Rio de los Americanos was a 35521 acre Mexican land grant in present-day Sacramento County, California given in 1844 by Governor Manuel Micheltorena to William Leidesdorff (1810–1848).
 The grant takes its name from Río de los Americanos, the name of the American River during the Mexican-rule era.
 The grant originally consisted of 8 square leagues and extended from the eastern border of John Sutter's New Helvetia (east of Sacramento) 4 leagues along the south bank of the American River, to the eastern end of present day Folsom, and included present-day cities of Rancho Cordova and Folsom.
The All-American Canal is an 80-mile (130 km) long aqueduct, located in southeastern California.
 It conveys water from the Colorado River into the Imperial Valley and to nine cities.
 It is the Imperial Valley's only water source, and replaced the Alamo Canal, which was located mostly in Mexico.
 The Imperial Dam, about 30 miles (48 km) northeast of Yuma, Arizona on the Colorado River, diverts water into the All-American Canal, which runs to just west of Calexico, California before its last branch heads mostly north into the Imperial Valley.
 Five smaller canals branching off the All American Canal move water into the Imperial Valley.
 These canal systems irrigate up to 630,000 acres (250,000 ha) of crop land and have made possible a greatly increased crop yield in this area, originally one of the driest on earth.
 It is the largest irrigation canal in the world, carrying a maximum of 26,155 cubic feet per second (740.6 m/s).
 Agricultural runoff from the All American Canal drains into the Salton Sea.
