Sounds like it could be developed into an absolutely awesome SMB fishery! Maybe some trout as well. Pray tell why you haven't shared pictures of this great sounding place with us yet, CBopp?

I like your idea of trying to avoid the typical stocking plan and think that you could do some really cool stuff with that much water and with cold water species that aren't found in the typical pond. Unfortunately, I don't really know what those are, but I'm confident the folks here will have some ideas.
