History of the Everglades Timeline

(10,000 BCE - Present)

The Everglades is a vast subtropical wetland ecosystem in southern Florida with a rich history spanning thousands of years. Home to Indigenous peoples like the Calusa and Tequesta, later the Seminoles, it was explored by Europeans in the 1500s. In the 19th and 20th centuries, large-scale drainage and development dramatically altered its landscape. Growing awareness of its ecological importance led to the establishment of Everglades National Park in 1947 and ongoing restoration efforts that continue today. More Less

Indigenous Peoples and Early History

Central and Southern Florida Flood Control Project authorized

1948

Congress authorized the largest civil works project in history up to that time, tasking the Army Corps of Engineers with constructing 1,000 miles of levees and canals, water control structures, and pumping stations across the Everglades.

Water Conservation Areas established

1950 - 1959

As part of the flood control project, the Corps carved the northern Everglades into Water Conservation Areas 1, 2, and 3 behind levees, fundamentally compartmentalizing the historic flow of water southward from Lake Okeechobee.
