Pond Boss Forums POND CONSTRUCTION Soil questions Digging a dam in the winter

I've been holding off saying anything because I don't really know.

On the positive side I see road construction crews running whenever the weather and frost allows. They need compaction but they don't need to hold water either.

I would think as long as the clay had the correct moisture content for compaction and the contractor had equipment big enough to work the area without it freezing the layers it probably would be ok. But that is entirely a guess.

I answer mostly to let you know people are reading your post. I think the problem is most of us just don't know.
