Thank you all, I have read about the permitting requirement for the state. It is pretty sad how little diversity we have with native fish in our fresh water in this state. It seems like Yellow Perch are everywhere. I haven't come across a pond of any size that isn't full of them.

I'll take your advised and talk with the state before any digging starts.

If, however, I'm not limited on fish choice by the state (due to having such a low risk of contamination) What would you recommend for pond depth and species?
