South of the City of Los Angeles, the river flows through the cities of Vernon, Maywood, Bell, Bell Gardens, Cudahy, Southgate, Lynwood, Compton, Paramount and Carson on its way to Long Beach. The Rio Hondo joins the Los Angeles River at Southgate from the east, connecting it to the San Gabriel River. The last tributary mingling with the Los Angeles River is Compton Creek. South of Compton Creek, the river flows down between a concrete or rock channel into the estuary in Long Beach, right by the Queen Mary. The last several miles of the river are soft-bottom and lined with rock riprap, and are a favorite spot for shorebirds.
