Question: Which of the following is located in Sacramento County: Imperial Dam or Folsom South Canal?
Context: 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. Folsom Boulevard is a major east–west arterial in Sacramento County, California in the United States.  Its western terminus is at Alhambra Boulevard in the East Sacramento section of Sacramento and its eastern terminus is at Greenback Lane in Folsom. Folsom is a city in Sacramento County, California, United States.  It is commonly known for Folsom Prison and Folsom Lake.  The population was 72,203 at the 2010 census. Lake Natoma is an intermediate lake along the American River, located between Folsom Dam and Nimbus Dam in Sacramento County, in the U.S. state of California.  The lake is located within the Folsom Lake State Recreation Area. The Imperial Diversion Dam (National ID # CA10159) is a concrete slab and buttress, ogee weir structure across the California/Arizona border, 18 mi northeast of Yuma.  Completed in 1938, the dam retains the waters of the Colorado River into the Imperial Reservoir before desilting and diversion into the All-American Canal, the Gila River, and the Yuma Project aqueduct.  Between 1932 and 1940, the Imperial Irrigation District (IID) relied on the Inter-California Canal and the Imperial Canal and Alamo River. California State Prison, Sacramento (SAC) is a male-only state prison located in the city of Folsom, in Sacramento County, California.  The facility is also referenced as Sacramento State Prison, CSP-Sacramento, CSP-SAC, and occasionally, New Folsom or New Folsom Prison which was its official name prior to October 1992. Rancho Seco Recreational Park is a recreational area located in the California Central Valley near the Rancho Seco Nuclear Generating Station in Herald, California.  It is open to the public for camping, fishing, hiking and water activities.  Boats are restricted to outboard electric motors which improves the lake's use as a swimming hole.  The lake is fed by the Folsom South Canal. The Folsom South Canal is an aqueduct in Northern California in the United States.  The canal diverts water from the American River at Nimbus Dam in Sacramento County and travels about 26.7 mi in a southerly direction, terminating near Clay, about 10 mi northeast of Lodi.  The canal is operated by the U.S. Bureau of Reclamation, as part of the Auburn-Folsom South Unit of the Central Valley Project.  It is contracted for irrigation, industrial and municipal water supply; formerly it provided cooling water for the Rancho Seco Nuclear Generating Station.  It is also connected to the Mokelumne Aqueduct, which provides a large portion of the San Francisco Bay Area's water supply. The Sacramento County Jail is the county jail for the Sacramento County area serviced by the Sacramento County Sheriff's Department.
