Yes there are alligators. Will they bother you, that's very unlikely. Just based on my own memory the last non-fatal attack was a couple of years ago. I just checked online and the odds are 1 in 24,000,000 (how they calculated that is a mystery). I will say do not allow your dog to swim, especially smaller ones since they can be in danger. And don't swim in poor light, near dawn, twilight or in the dark since that's when the gators come out.
Anyway I've been swimming in those lakes and ponds since the 1960's and have never had a problem yet. BTW do not feed the gators.
If you want to see a lot of gators, head down to the Everglades National Park and take US 41 across the north edge until you get to the Park's Shark Valley entrance. Take the tram ride or rent the bikes they have for the loop trail. You will see a LOT of gators and those gators I would not swim with....heh.
There is an Alligator Farm in St Augustine, but they only have caged gators that are more sad than threatening. However is you want to see, and very closely see, egrets , herons ect. in breeding plumage, then that's the place to go in the spring. Right now probably. You'll get within a few feet of the nests in some cases. Photographer's paradise then.
One other thing, if the water has a brown tint, that's normal and just comes from oak leaves. It does not mean the water isn't clean. I knew a women from NY who refused to swim in the brown water.
