What is hard here
Clarity swings from 1.3 to 8.3 feet between our readings — the water you meet is not the water someone photographed. Winter water drops to 59°F, and the warm-water species stop feeding well before you do. Alligators live in Florida fresh water. Keep clear of the bank edge at dawn and dusk, and keep pets away from it. Summer water sits at 84°F: heat and afternoon lightning are the real risks, not the fishing.
