Jose, Mike has written the best book on pond building that I've seen. "Just Add Water" is worth many times the cost. Especially since you are doing a 20 acre one.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.

Without a sense of urgency, Nothing ever gets done.

Boy, if I say "sic em", you'd better look for something to bite. Sam Shelley Rancher and Farmer Muleshoe Texas 1892-1985 RIP
