There is no clay bottom. It is a dammed up ravean. I think draining it would be tough because it has 4 natural springs in it. The drop well run constantly. If fact there is a small current in the pond. I am still mulling my options over. This sight has given me a lot of insight. I sure it could use 2 silt traps where the ditchs run into it but $$$$ is a concern.
