Pond Boss Forums POND CONSTRUCTION Soil questions Need a little advice and help from my friends

I'm reposting this here from another thread, as suggested by another member.

I'm really having a hard time with getting a local pond builder and have gone the NRCS route with no success.

I wish an expert pond builder would chime in with some advice, that has actually repaired a large ledge leak.

"I priced out more Benonite clay yesterday, since I haven't had any luck finding a blue clay source. Maybe if I pack the open ledge with a ton and a half of Benonite in 6 inch lifts I can stop it? The area is only about 20 feet in diameter where I couldn't compact the soil when I mixed in the Benonite two years ago. This would even allow me to have a deeper pond.

The first time I back filled at least four feet of soil over the area. The next time I mixed in the Benonite and compacted over the whole basin. Which left me with the soft area I couldn't compact."

Contact Mark Cornwell who is a fisheries science prof in upper NY. He knows a guy up there who has built thousands of ponds in the area.

You could also call Bob Lusk as he worked the area (NY) a bunch.


Here is info from prior thread.

The Nov/Dec 07 issue of PB mag has an article by Doc Cornwell on building NY ponds and pond building legend Ed Nadeau (60 years exp and 5000 ponds in NY). Doc Cornwell can be reached at CORNWEMD@Cobleskill.edu -- see A. below and one on design considerations for Northern Ponds --- :

Not to be picky, but I'm in New Hampshire. Did you mean he knows of pond builders in New Hampshire?
