Kimball Island (formerly known as Hammond Island) is a small island in the Sacramento–San Joaquin River Delta. It is located in Sacramento County, California, in the United States. Since its discovery, it has been used to grow barley, farm fish, cultivate cannabis, and as residential land. Currently, however, it is uninhabited; since 2000, it has been left to "forever be a wetland habitat", and is sometimes used as a fishing spot.
