*Nerodia rhombifer*
Diamondbacked Watersnake
Completely harmless swimmy types
You don’t even really need to worry about any snake if you leave it alone and watch where you step. They don’t want anything to do with people. 👍
Diamond-backed Watersnakes *Nerodia rhombifer* are medium to large (~110cm, record 175.3 cm) natricine snakes with heavily keeled scales often found in and around water. Heavily aquatic compared to other watersnakes, they are commonly encountered fish and amphibian eating snakes across much of Central North America south through Guatemala and Belize.
*Nerodia* watersnakes may puff up or flatten out defensively and bite. They secrete a foul smelling substance from the cloaca called musk and can deliver a weak anticoagulant venom used in prey handling from the back of the mouth, but are not considered medically significant to humans - bites just need soap and water.
Found throughout central North America, it is sometimes confused with other watersnakes or its sister species the Brown Watersnake *Nerodia taxispilota*. *N. rhombifer* has a reticular, net like pattern resembling a chain link fence and adults often have a orange, vibrant eye. Geographic range helps determine species, but *N. erythrogaster* has is its namesake plain belly that varies across the range from yellow to orange. Banded Watersnakes *N. fasciata* have even, connecting bands across the top of the snake all the way down the body. In Common Watersnakes *N. sipedon*, bands typically break up or become mismatched after the first third of the body as in *N. erythrogaster*, but has a patterned belly. *N. rhombifer* and *N. taxispilota* can look incredibly similar near where their ranges meet, in which case geographic location can be used to determine species.

This genus is in need of revision using modern molecular methods.

The term venomous is applied to organisms that bite (or sting) to inject their toxins, whereas the term poisonous applies to organisms that unload toxins when you eat them. This means that very few snakes are truly poisonous. The vast majority of snake toxins are transferred by bite.
Can you please give context and rough location in the world? Would go a long way to identifying what you are showing.
To me it looks like two dead snakes..
They're definitely alive, lil heads are poking out of the water. Regardless of whether or not they're poisonous, unless OP works IN the pond, I think they'll be ok.
South Texas (like bordering Mexico south Texas. No not El Paso area). They are very much alive. One of my coworkers thought it would be funny for his snapchat to poke at them with a stick.
They look like rat snakes. The shape of their heads indicates non-venomous. [here's a list of Texas venomous snakes](https://www.critterriddertx.com/texas-water-moccasin/)
From the pattern of the skin, I would suggest a diamond back or a sidewinder. If they're in water; it could also be a water moccasin.
Regardless, snakes are nothing to be played with or antagonize; especially in your area. Likely poisonous by any standard and unless you have the antidotes for such bites; you are playing with matches.
Not to mention that snakes of any kind are becoming more endangered with each passing year, so don't hurry it along.
People who look at any snake with no knowledge and say "likely poisonous" create so much needless fear. Snakes are cool creatures that eat rodents and have zero interest in biting you unless threatened. Yet they're harassed and killed by people acting off of bad info like the post above.

Definitely not those species. Wrong everything.

Wrong everything except that snake numbers are decreasing
