I have a pond of about 3 acres. It was completed in December 08. It is now full and real muddy. The valve I installed in the pond to drain the pond is a slide valve. It was leaking so we installed a riser on the pipe which slowed the leak there. But where the pipe comes thru the back of the dam it appears to be leaking from about ground level to about a foot above the ground elevation. Should I worry about the leak or see if it will seal itself. I will post some pics of leak if it dries up enough here to see the color difference. Also as far as muddy water should I wait and see or add chemicals to clear up.
