Thanks for the help folks. Shawn wrote in for me since I am pretty unfamiliar with the whole pond concept. Not a whole lot of planning, just rent a dozer and dig a hole. I figured since me neighbor to the north and my neighbor to the south have ponds on the same old creek line, it would be the right spot. Will definitely be finding some bentonite though. Luckily I am a drilling engineer for an oil company so I should have some contacts that can supply me with some drilling mud or some bulk bentonite.
Thanks again for the help, I'll keep you informed of the progress.
