Pond Boss Forums POND CONSTRUCTION Soil questions Web Soil Survey says "very limited"

Thanks Esshup. I've been around, checking in every now and then. Finally have a potential pond site.

Besides looking for good clay, I assume I should be looking for a problem rock shelf/bedrock. The "ditch" or creek channel is probably 8 foot lower than the bank, and it would be difficult to get a backhoe down there to dig a hole in the bottom of the channel. (water only runs after a rain) Would that be required? Otherwise dig 3/4 holes in what would be the deepest part of the pond, and under where the dam would be?

Thanks
