## Narrative

The spillway pipe of CP-1 pond which runs through the dam in a morning glory arrangement developed a leak around the pipe. As the flow around pipe increased it accelerated erosion making the leak larger.  The end result was the CP-1 pond was drained into an adjacent wetland.  The water was unimpacted water.  The dam surface (roadway) did not show any subsidence.
