I don't have any snake shot ammo. Maybe I should.
I am working on a channel drain for the front of the house.

Yesterday I felt something looking at me as I used a pick axe to shave a 1° slop in the channel.
When I saw it in the grass, I took a photo before pulling it out.

As I pulled it out, I recognized I had hold of a two and a half foot water moccasin, way too far behind its neck.
Edit: Robert identified it as a common water snake. He is correct, it now looks like a Diamond Back Water Snake (non-venomous.)Lynnette recognized it too and started hollering, "Get away from it!"
I let go and it tried to get away but went the wrong way, ending up in a corner of the house foundation.

Clever snake. With its head and neck up against the concrete I could not get a grip on its neck. If I tried it would just pull back and strike my hand.
I never needed a snake tong in Arizona, rattle snakes are more aggressive and therefore easier to grab by the neck. I have a snake tong on order now.
Lynnette to the rescue... she came out with a shotgun and ordered, get back, get back! The snake must have thought she was ordering it back to the creek because it took off toward the creek. I was backing up from the shotgun when... BAM!!! Lynnette missed the snake by 6 inches. The snake changed course back into the grass.
It is hard to miss a varmint with snakeshell (or snake shot) because pistols have no choke in the barrel.
