The 400-acre Agua Hedionda Lagoon is one of the threatened coastal wetlands on the Southern California coastline. Draining 135,000 acres in the heart of the burgeoning metropolitan area of San Diego's north county, the Lagoon watershed is a sensitive and vital ecosystem. It is home to juvenile fish, crabs, hundreds of species of marine life and waterfowl, including an array of threatened and endangered species. It is also provides a much needed respite for migrating birds. The Lagoon is unique in that it has many current uses such as a YMCA day camp, recreational boating, a mussel and abalone aquaculture facility, a white-sea bass breeding and research center and a power generating facility. The Lagoon's various usages, and the many activities and ecosystems it supports, makes it a distinctive and precious natural resource unlike any other.
