Before the first attempt at draining the Everglades in 1882, the entire watershed extended from Orlando to Florida Bay comprising the Kissimmee–Lake Okeechobee–Everglades (KLOE) watershed. Kissimmee River outlets flow into Lake Okeechobee, which sits above sea level. Only two seasons exist in the Everglades: wet (May to November) and dry (December to April).

As a result, the landmarked area was decreased to above , most of which overlapped parts of the original designation.
