Southern Banded Watersnake

Thanks for the ID, Cody!

Cottonmouths will have a slit pupil for an eye, as well as a grey line that runs across the top of their eye. Your snake has a clearly visible round pupil in the second image. Most nerodia (nastix) have the ability to flatten their head and give a more triangular appearance which leads many people to think they are the more dangerous cottonmouth. Look for the eyes though and you will know without a doubt when dealing with heavy bodied snakes in or near the water.

I agree! It's got that squat type of body and looks like the head might be triangular...

It could be a water moccasin. They have a variety of colors and pattern.
