I've spent enough time in Florida and Louisiana that I got well acquainted with cottonmouths. I've seen several around Flat Creek, my granddad showed me the first one 50 years ago. A couple of years ago I was fishing close to Shell Knob, the day was flat and I noticed a strange movement toward the back of the cove, kind of a small wake. Fired the trolling motor up and went to investigate. What I found was the biggest cottonmouth I've ever seen crossing the cove. That snake was close to 6 feet long and as big around as my leg, never seen one even close to that size. Saw one close to a dock, in the Campbell point area, warned a guy that came down with a dog about him and he said he was a pet, so they know they have one close by. I've saw one on LOZ a few years ago also. We have plenty of cottonmouth in this area.
