You are correct, but you can find springs like Silver Springs all over the state.It was clear because it was being filled with well water... but it was never intended to stay that way. If I dug a pond in my backyard and then filled it with a garden hose it would be clear too.... but that would only last so long. The only place I can think of in Florida where you find a large super clear body of water would be Silver Springs state park and its only clear because it is constantly fed by the natural artesian springs... You just don't have that where Seven Seas Lagoon is.
