Geography According to the United States Census Bureau, the CDP has a total area of 21.6 square miles (56 square kilometers), of which, 21.5 square miles (56 km²) of it is land and 0.04 square miles (0.10 km²) of it (0.20 percent) is water. The place name, Granite Bay, is derived from a bay in Folsom Lake, a reservoir on the east side of the town created in 1955. The entire town is underlain by granodiorite of the Penryn Pluton of Cretaceous age, hence the geological basis for the place name.

Cultural Resources The history of Granite Bay started with the Maidu Indians, and it continued when miners, farmers, and others seeking to do business came during the Gold Rush to strike a fortune. The Granite Bay area was officially recognised on July 28, 1987 by the Board of Supervisors.

The Nisenan, also known as the Southern Maidu, were one of three Maiduan-speaking tribes in the northern half of the Sacramento Valley. The Granite Bay area is located in the ethnographic territory of the Nisenan. The Nisenan lived along the American, Yuba, and Bear Rivers, as well as the Feather River, to which their territory extended.
