Wow thanks for the reply guys. I will have to look into the book. I don’t know the exact amount of watershed in the area but I do now that it is pretty good as the side yard is slightly downhill from my pole barn and house so all runoff from them go right into that yard. As far as fish, well we are doing this pond more so for swimming and rec so I will definitely do my research in regards to what fish I stock and how to properly stock it. Thanks for the advice guys keep it coming.
