Snake ID

We think this is a Western Aquatic Garter Snake as it seems to fit the description and it or it's close relatives hunt tadpoles and water insects in our pond, but if anyone can provide a better guess or a subspecies diagnosis, I'd appreciate it.

For reference, we live in Western Washington a few miles south of Olympia.

I'll post another couple of views.

Thanks,

Hi, Dennis.  You probably already know this, maybe most people do, but just for those who don't, the blue eye appearance is because the snake is getting ready to shed its skin.  I can tell you a couple of other things I found in research if you want me to, but I haven't found a snake that looks exactly like this one if that's the only thing that will be helpful.
