I live in Texas. My guess would be a cottonmouth aka water moccasin, if I saw something that looked like that. Also, I would pick up the nearest hoe and separate the snake’s head from it’s body. Country folk take no chances where poisonous or possibly poisonous snakes are concerned.
Looks like a Cottonmouth Water Moccasin... killed a bunch of those serpents.

Looks like a moccasin to me, as well.
We found one in the garage a few weeks ago. Before we decided what to do with it, we took a picture, covered it with a box and tried to ID it.
It was a toss up so we killed it. Actually, my husband kiled it while I said not to leave snake splatter on the driveway.
