Be careful sticking your hand in the water there. I was fishing that same culvert in Ding Darling and there were two 6' bull sharks there going in and out of that culvert. They were in a very aggressive hunt mode.
It really was crazy. I couldn't believe it. God bless. Enjoy visiting Sanibel through your lens. We live in Orlando and go to Sanibel every summer. It was great to be back this summer. First time back since Ian.
