Tim what he needs is a 750 Komatsu lol. I helped a friend of mine this weekend that has a quarry near by and they are stripping over burden with a 750 Komatsu (9yard bucket) and articulated trucks. He wanted a pond and called me up to see if Id drop it in the ground. With him and his son both in 30 Ton Moxy's we dug out a 1700 yard pond not counting the slopes. We curved a few edges around trees and such then i came in with a paddle wheel scraper and did some touch up work. Also used a D5b and a TW15 Ford with a Beegee board to spread some of the topsoil and walk it in. They have a 6000 gallon water tanker made from an old Terex scraper they are gonna take the wate they pump out of the quarry and haul it into the pond. They will do this till we get the trenching bucket for the 300 Komatsu to dig the trench.

Well, I guess that depends where you measure the pond size. If the 60 x 120 size is measured at the 9' depth (the bottom of the pond), you're right. But then, the pond at the top of the bank would be 114' x 174' with a 3:1 slope (it takes 27' horizontally to get to 9' vertically, on each side, or 54'). What I assumed was that the top of the banks would measure 60' x 120', which, less 27' on each side for sloping, would give a pond bottom of 6' x 66' at the 9' depth. If what he's after is 60' x 120' of water surface area, the top of the banks have to be 12' wider on each side (using the 4' water level and 3:1 slope), or 84' x 144'. In that case, the bottom of the pond would be 36' x 96', still assuming 5' water depth and 9' from the bottom to the top of the banks.

The only reason I'm going through all this is because that's what I had to go through in my own case. I have a need for a certain number of cubic yards for fill, and I have to be sure I size the pond at least big enough and deep enough to get the minimum fill. On the other hand, each excavated (and moved & graded) cubic yard is $2.50, so I have to be sure I don't make it too big. Since I plan a very irregular shape and varying depths, it got into quite an exercise in geometry. I think my poor brain was fried by the time I was done, and I know I filled almost an entire pad of graph paper /forums/images/graemlins/crazy.gif.
