Everglades Restoration Timeline


River and Harbor Act of 1930

Following two hurricanes in 1926 and 1928, which killed more than 2,500 people, Congress enacted the Rivers and Harbor Act of 1930, authorizing the construction of 67.8 miles of levees along the south shore of Lake Okeechobee and 15.7 miles along its north shore. After another major hurricane in 1947, Congress took additional action to construct a new dike system which was completed in the 1960’s and named the Herbert Hoover Dike. Today the dike system contains 143 miles of levees, gates, and other structures.
