Nice Pictures! I can answer your question. That black snake is a black rat snake. Was that midland water snake (subspecies of the northern water snake) found at LaRue Road. I have never found a midland water there before. In fact I don't think I know anyone who has seen one there either. I'm sure they have a good population there, but it surprises me that you saw one. They generally inhabit lakes, creeks and rivers. One doesn't usually see a midland or northern water snake in cypress swamp. I have seen them up north in oxbow lakes. I did see a midland water snake at Mingo swamp in a ditch, but that is far as my northern water snake experience goes. Nice find. Ryan

You don't say exactly where you are - for reptiles and amphibians, the locality tells which subspecies, but it is a baby Rat Snake. Rat Snake, WIkipedia Where you are is important to know what it will look like when it is grown. Totally harmless BTW, and can be picked up and played with.

Not sure where you are located but just generalizing, the head is the wrong shape to be one of the venomous North American snakes. The exception to the triangular shaped head would be the coral snake and it certainly isn’t one of those. Just leave it be and let it go about its business of eating vermin.
