On February 2, 1992, a catastrophic rupture occurred in Sain Diego's wastewater discharge pipeline 0.6 mi offshore in 35 ft of water. For the following two months, approximately 180 million gallons per day of treated sewage effluent spilled into the nearshore marine environment of Point Loma, including the western shore of the nearby Cabrillo National Monument. The National Park Service has been monitoring key intertidal resources at the Monument semi-annually since Spring 1990. Their Spring 1992 survey took place during April 11-13, one week after cessation of the spill. This report presents the findings of an additional follow-up survey for the San Diego Water Utilities Department, conducted on June 2-5, two months after the spill ended. In order to determine if the spill impacted rocky intertidal habitats within the Monument, the same National Park Service methodology was used to assess representative plant, invertebrate, and fish populations
