So, what does it take to have a pond like this

PS - nice pond BTW.

What I mean is, can you have Koi in this kind of environment, or do you
need to supplement it with filtration and aeration?

I guess it is a broad question... Sorry. Just trying to decide of this
is a type of pond that could easily be taken on on a 100 acre parcel I
have in mind...
