西沙加缅度毗邻加州首府沙加缅度，中间以沙加缅度河分开，西沙加缅度位于西岸，沙加缅度位于东岸，因此这两个城市也位于两个不同的郡，西沙加缅度位于优洛郡，而沙加缅度则位于沙加缅度郡。

West Sacramento (also known as West Sac) is a city in Yolo County, California. It is contiguous with Sacramento, but is separated by the Sacramento River which is also the county line, so West Sacramento is in a different county from that of Sacramento. It is a fast-growing community; the population was 48,744 at the 2010 census, up from 31,615 at the 2000 census. The traditional industrial center of the region since the Gold Rush era, West Sacramento is home to a diverse economy and is one of the area's top four employment centers.
