I'm building a two acre foot pond to irrigate our permaculture demonstration site and I'm having difficulty identifying appropriate soil for building the dam and lining the pond. We have quite a mix of soils varying from sandstone-derived loam to serpentine-derived clay. Is the clay content the most important variable? We have some very high clay content soil that has a crystal like structure when exposed. It is very expansive, and when dry, it gets blocky and is easily broken up. I think it would be fine where it will be under other layers or always wet. Does anyone have any answers or comments on this?
Thanks,
Rain
