A question back to Bob - Isn't a spillway just used when the pond is in overflow condition? I'm not sure why you put that together with water usage. And to both Bill and Bob, if betonite is used, to what height up the pond side should that go? Directly below the anticipated water level? If there were an embankment condition, couldn't that threaten the structural integrity of the dam area above the betonite line during overflow conditions?
Thanks for hanging in there with my questions!!!
