The old drain pipe had rusted off and was letting a trickle of water through. The pond dropped a couple of feet each summer but overflowed most of the year. I needed a way to get the water down and keep it low while I built a dock.
This picture shows the full pond from the bank where I wanted to build the dock. The bluegill is one I caught there - the pond is full of them and I feed them most every day.
