Re: My Pond Project Great pictures. It's an amazing project that you are undertaking, especially with having to pump out the water so that you can get back to digging. I did just the oposite, in almost the same way. I bought a 3 inch trash pump and put an old fuel tank on top of it with a wood frame. Your metal frame and matching paint job on your tank looks very profesional. Much nicer then mine!!!
With all the dirt you are removing, can you just dig down 4 feet in areas before you do some serious digging to make sure you don't hit bedrock? If you do, you should be able to fill the hole and compact it without creating a leak. If you don't hit rock, you know that you are good to go for at least another two feet of depth. I'd always try to have at least two feet of good clay underneith you just in case the bedrock is just inches under your test hole.
Thanks for the update, it's a fun project for us to follow along,
