There is no record of a man-made fishery of San Leandro Creek. However, there are three distinct fisheries on San Leandro Reservoir (USL) and Chabot Reservoir, and one above USL. The origin of the fish in either side of Chabot Dam is unknown. The fishery above USL consists of protected genetically pure native steelhead. Existing reservoir releases maintain the creek in the channel for several thousand feet downstream and keep the fish in good condition.
