We have the diamond back water snakes in our ponds but they are more the brownish color like the water moccasin pictured. But can definitely tell by the head that ours is not poisonous. The poisonous snakes have that broad more diamond shaped head where the poison glands are. Non-poisonous heads more slender. At least that is the way it appears to me.
Saw one in our old pond last summer with a 4" or so bullhead in its mouth swimming out to deeper water. When I came along it was at the bank and I scared it, so it swam away, but was not going to give up its meal so was swimming on the surface with its catch. Have a half dozen 13" LMB in that pond now, so it better watch out or it will become the meal.
