Which of the following is located in Sacramento County: Imperial Dam or Folsom South Canal?
Imperial Dam 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.
Butte Creek (Butte County, California) Butte Creek is tributary to the Sacramento River, joining the river in the vicinity of Colusa, California, United States. About 93 mi in length, it runs through much of Butte County, California (the county, however, receives its name from the Sutter Buttes in Sutter County, California). It travels through a spectacular mini-Grand Canyon as it reaches the Sacramento Valley floor, where it then flows somewhat south and west of the city of Chico towards the southwestern corner of the county.
