The San Diego-La Jolla Underwater Park is a continuing community project to preserve the natural ecology, reestablish underwater sea life, and maintain the natural beauty of the shoreline. It was created in 1970 when the San Diego City Council dedicated 6,000 acres of city-owned tide and submerged lands as an underwater park. The park extends from Alligator Head in La Jolla southward to near the northern boundary of the Torrey Pines State Reserve. Within it are two special areas created by the California Fish and Game Commission, the Ecological Reserve and the Marine Life Refuge, which are regulated to protect native marine and geological resources. To enhance fish, invertebrate, and plant habitats, Santa Catalina quarry rock was dumped in 70 feet of water near Scripps Canyon in 1964 to create the first of two artificial reefs, and the other reef was created in 1975 and 1979 in 40 feet of water offshore from the Glider Port. Sport and commercial fishing are permitted within the park but not in the Ecological Reserve. The San Diego Marine Life Refuge was established in 1929 by the California Fish and Game Commission to allow licensees of the Regents of the University of California to take, for scientific purposes, any invertebrate or specimen of marine plant life without a department permit, while making it unlawful for the public to take or possess any invertebrate or specimen of marine plant life there; recreation and fishing are permitted within the refuge, which is intended to further the University of California’s knowledge of the physical and biological perimeters of this marine habitat between two major underwater canyons. The Ecological Reserve grew from a recommendation by an advisory committee on regulating uses for the underwater park and from a 1971 council resolution authorizing the California Fish and Game Commission to establish it. This “Look But Don’t Touch” area covered about 514 original acres and increased to 533 acres in 1981. Buoys mark the outside perimeter, a boat-free swimming zone, and a 5 miles per hour zone within the reserve, where all fishing is prohibited and marine life, geological formations, and archeological artifacts are protected.
