Mission Bay, originally known as "False Bay" by explorer Juan Rodriguez Cabrillo in 1542, was once a vast tidal marsh and wetland. For centuries, the San Diego River intermittently flowed into either False Bay or San Diego Bay, causing concerns about silting up the main harbor. Efforts to control the river's course, including the construction of a dike in 1852, eventually led to the river being permanently diverted away from Mission Bay by 1877, setting the stage for its future development. The transformation into the recreational hub seen today began in the 1940s, primarily after a 1944 Chamber of Commerce recommendation to develop the marsh into a tourist and recreational center. Massive dredging and filling operations, involving the movement of 25 million cubic yards of sand and silt, reshaped the natural marshland into the largely man-made aquatic park we know today. This extensive project, which continued through the 1950s and 1960s, created the numerous islands, channels, and beaches that characterize Mission Bay Park, officially making it the largest aquatic park in the United States.
