Mine comes and goes. I think he moves up and down the swamp. He is very good at concealing himself. They will stick the very tip of his nose out, catch a breath and go back under.
However, I must say that long-term gators will become a problem (IMO). Mine is losing his fear of humans. A couple of weeks ago I was cutting dead timber out of the water. He came to 10 feet from me and watched the whole thing. I could see what he was thinkin..."man if he didn�t have that chain saw - I could take him".
There are lots of opinions about gators eating all of your fish. I have not been able to prove/disprove this for myself. With all the turtles, birds and snakes, I wonder what impact a small gator has since he is eating the competition. Perhaps I am better off with a small gator vs. a bunch of the other? It�s hard for me to see any impact from the gator so far.
I do feel the bigger he gets, the bigger problem I will have from him eating my big fish and from a safety perspective. Sooner or later he must go.
