Yes east of 45 has all clay in the ground. The best dirt to build a pond in. I live in ennis and there are lots of ponds out here. The Canton area would be a good spot. My mom owns 400 acres there and the land is sandy loam. The biggest trees and best grasses you can find. There is a doctor that lives down the road from her that owns 60 acres and has a 25 acre lake on it. Its beautifull!
