Large sugar plantations were established around Lake Okeechobee. By the 1950s and 1960s, the cultivation of citrus, vegetables and cattle were also important to the economy. United States Sugar, however, remained the dominant manufacturer in Clewiston, which became known as "America's Sweetest Town." On June 24, 2008, however, Governor Charlie Crist announced that the state of Florida has arranged to buy for $1.75 billion the company's 187,000 acres (75,680 hectares), including the refinery in Clewiston. The farmland will be converted into reservoirs and water-filtering areas as part of the ongoing restoration of the Everglades ecosystem. United States Sugar will lease its former facilities from the state for about five years to help defray the cost, and then cease to exist.
