I am going to drop the $$$ to build a 2 acre pond in SW Arkansas on my parents old home place, which I will live on some day. The site is in a low place in between two hills and fed by a small seep. Any advice on minimum depth, contour, dam construction, etc??? I plan to stock this with the typical fish varieties (channel cats, bass, bluegill)& feed them. Is there any type of testing that should be done in advance to insure the site will hold water??? Thanks.
