The Diamond-back (or backed) Water Snake is a long, heavy-bodied, tan to gray-brown snake with a pattern of dark brown to black chain-like markings. The belly is yellow, but with dusky brown markings. As the name implies it lives in slow moving waters and is found all over Louisiana. These beautiful snakes eat fish, frogs, and a few birds. Plus it is a non-venomous/ non-poisonous snake. But the bite will still hurts.
The snake you are describing is likely a diamondback water snake. These snakes are non-venomous and are commonly found in freshwater areas across North America. Their brown bodies with black diamond-shaped markings and silver bellies are distinctive features.
A black snake with three bright yellow lines is likely a species of king snake (Lampropeltis), known for their distinct coloration. King snakes are non-venomous and native to North America, with species such as the California kingsnake or the Eastern kingsnake exhibiting this color pattern.
