The Famosa Slough is a 37-acre wetland located between Ocean Beach and the San Diego Sports Arena area. It is bisected by West Point Loma Boulevard and bordered by Famosa Boulevard on the west. The channel portion of the slough extends from West Point Loma Boulevard, northward, to the San Diego River Channel. The slough is flushed with salt water from the river channel, and also collects rainwater from the surrounding neighborhood.
The 12-acre channel portion and the 25-acre southern portion of the slough are owned and maintained by the City of San Diego. The southern portion was acquired by the city in September 1990. Both portions are accessible by the public, and benches are located at view areas.
