Geography and ecology of the Everglades is nourished primarily from the atmosphere. 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). Average annual rainfall in the Everglades is approximately , though fluctuations of precipitation are normal. Droughts, floods, and tropical storms are normal occurrences in the area. When Lake Okeechobee exceeds its water storage capacity during the wet season, it pours slowly
