Pond Boss Forums Thread Like Summary - Bouncy Clay Bottom

I’m having a new 3/4 acre pond dug and initially it looked great. As the basin was being dug, builder ran into sections where the surface would give under the weight of the equipment. Then water began to seep out and in a few spots bubble up.

Now the surface is all very good clay and the clay itself isn’t saturated, it just seems to be layered over something squishy.

This has limited his ability to drive the dozer over these sections and compact.

He came with good recommendations and is telling me not to worry, but this is keeping me up at night.

The effected section is perhaps a quarter of the total basin and in the shallow area, which would be 5-8 feet average. The deeper section, near the dam, is perfect and would be 12’ or so deep.

I visited the site yesterday and when walking on the bouncy surface, it moves under foot, so getting his D6 over it would be scary.

Any thoughts?

All disturbed area was planted with grass and covered with straw. Already have quite a bit of germination, so hoping it continues for the reason you stated.

Thanks for checking in buddy.
