The Salton Sea was an accident of man created when heavy rainfall caused the Rio Colorado to swell and breach an Imperial Valley dike in 1905. For two years, water flowed into the Salton Sink and ancient Lake Cahuilla. Today, the sea is 227 feet below sea level, covers approximately 376 square miles, and is California’s largest lake. During the early 1900s, it became an important bird and waterfowl refuge. When many species of fish were introduced, the Salton Sea also became popular for boating, fishing, hunting, and camping activities. Motels, yacht clubs, and marinas developed around Salton City and North Shore. During recent decades, the sea has become polluted from agricultural runoff, creating a doubtful future for the Salton Sea. However, it remains a sanctuary for anyone who enjoys bird watching, desert landscapes, or beautiful farmlands.
