The focus of government agencies quickly shifted to the control of floods rather than drainage. The Okeechobee Flood Control District, financed by both state and federal funds, was created in 1929. President Herbert Hoover toured the towns affected by the 1928 Okeechobee Hurricane and, an engineer himself, ordered the Army Corps of Engineers to assist the communities surrounding the lake.[64] Between 1930 and 1937, a dike 66 miles (106 km) long was built around the southern edge of the lake, and a shorter one around the northern edge. It was 34 feet (10 m) tall and 3.5 feet (1.1 m) thick on the lake side, 3 feet (0.91 m) thick on the top, and 2 feet (0.61 m) thick toward land. Control of the Hoover Dike and the waters of Lake Okeechobee were delegated to federal powers: the United States declared legal limits of the lake to be 14 feet (4.3 m) and 17 feet (5.2 m).[12]
