We would like to build a pond on our 30 acre homestead in SC. We have clay and rock and sand soil. We will fill it with well water, water catchement from the roof and possibly end our graywater filtration there. The best (clay) soil is pretty much at the higher elevation of our land. The lower elevations are mostly sand and we know that won't hold water.
One concern is keeping it filled without running our well all the time. One factor here in the hot dry south (although we have had bunches of rain this year) is transevaporation. Would it help to dig a deeper pond with a smaller radius. We are thinking about 1/4 acre probably. We are also concerned with keeping water in. With our sand and rocks that might be an issue. Any thoughts out there?
Wish Sepp Holzer lived down the street!
