The same year the park was dedicated, two hurricanes and the wet season caused to fall on South Florida. Although there were no human casualties, agricultural interests lost approximately $59 million (equivalent to $ million in ). In 1948, Congress approved the Central and Southern Florida Project for Flood Control and Other Purposes (C&SF), which divided the Everglades into basins. In the northern Everglades were Water Conservation Areas (WCAs), and the Everglades Agricultural Area (EAA) bordering to the south of Lake Okeechobee. In the southern Everglades was Everglades National Park. Levees and pumping stations bordered each WCA, and released water in dryer times or removed it and pumped it to the ocean in times of flood. The WCAs took up approximately 37 percent of the original Everglades. The C&SF constructed over of canals, and hundreds of pumping stations and levees within three decades. During the 1950s and 1960s the Miami metropolitan area grew four times as fast as the rest of the nation. Between 1940 and 1965, 6 million people moved to South Florida: 1,000 people moved to Miami every week. Developed areas between the mid-1950s and the late 1960s quadrupled. Much of the water reclaimed from the Everglades was sent to newly developed areas.
