My small pond is only 30 yards above the main pond but the main pond is 100 yards above a dry creek bed and that's where the original contamination started. I have no idea how far the greenies and bullheads traveled up the creek bed but I’m sure it was a considerable distance. The main pond was cleaned out in the summer of 06 and what water was left treated with hydrated lime until it turn crystal clear and the crawfish and bugs all croaked so I should have started fresh and clean. I also stocked from a reliable source so I know that wasn't the point of entry. So unless you believe in the stork theory (wading bird) the only point of entry was from spillway runoff.
