NEfish, when I dug mine I had nothing but sand and gravel. I had to line it with clay. At the time (I didn't have Pond Boss to turn to) it seemed logical to fill the pond as soon as possible. Knowing the way clay will crack and hearing horror stories from others who have waited to have them fill on their own, I invested in a gas powered trash pump ($325)so I could pump from the creek that borders our property. If you don't have a creek or stream nearby, and assuming the water table is not too deep you could put in a 2" well rather easy. When I put mine in I rented a demolition hammer and they had a special bit with a collar that fit over your well pipe. You use a "sacrificial nipple" because it will get chewed up. I used my pickup truck and stood in the bed and used a ratchet strap to secure the pipe while I let the jack hammer do the work. This beats the heck out of using a sledge hammer. I had a 25'of 2" pipe sunk in minutes! I connected a 1 1/2 hp sprinkler pump to mine. In my situation I don't have enough ground area to provide adequate run-off, so I use the well to top it off when the level sinks. This year we have had so much rain that it hasn't been a problem. To me it was worth the extra money and effort to get it filled quickly. Good luck!

Dream it, Believe it, Achieve it!
