ABSTRACT:
A one-piece plastic back brace for a ditch dam is shaped like the V of the ditch. It has a groove on the top back edge that engages a span pipe which is placed across the ditch. An apron is mounted to the span pipe before the back brace is engaged. The apron folds back over the back brace to form a dam.
