I am still building a pond. It will have an "L" shaped dam and I have completed most of the side. I built part of it (we are using a layer of clay/gravel as caliche so I'm doing parts at a time). The part that I built had good clay and was moist enough to pack good.
I started the bottom of the "L" before Thanksgiving and it was clay marbled with a white sand. It was a little dry and packed but didn't pack as good as the first.
I decided to wait for a rain to finish but am tired of waiting. (If we get a big rain I will have 5 or 6 feet of water in my way)
What happens if you use dry soils for the dam? I am guessing that it will take longer to set and sag more and I'm okay with that. I can fix it later. Will the dam eventually set and seal like a good boy or will it always leak more?
