I'm an engineer based Inside The Beltway. I'm working on several projects for a client&friend on Bainbridge Island, WA. This includes a spa, a 20,000 gal. koi pond, and many other non-H2O projects.
You would't want to..... They might think you are lunch. And the pond is not that large an area; it's ~14 ft. deep as they hibernate down there all winter.
