Pond Boss Forums POND CONSTRUCTION Building a dam TOOO Deep?

I have + 20 feet of depth. I would only go 10 or 12 in the area we swim in next time. Otherwise the depth is no problem except I hit a coal seam down there and it leaks a little.
A big dozer will get compaction, a tiny one won't. Intermediate sizes can in good conditions. And if the dirt is moist it helps the compaction considerably whatever you pack with. I would suggest that if they do it all the time go look at their past projects in the area. If the past work is good you probably shouldn't have any worries.
