Tule Island is a small island in the Sacramento–San Joaquin River Delta, which exists as part of a complex of islands including directly-adjacent Fern Island and Headreach Island. It is a naturally-formed island, which was used in the early 20th century to farm potatoes, but now consists mostly of marsh. It is currently a habitat for waterfowl and is used as a fishing spot.
