Response
Additional Remarks or Updates The failure of this dam helped cause the downstream Gracie Creek Road Dam to overtop and fail. The two-lane state highway which washed out ran along the top of the Gracie Creek Road Dam. This dam was removed from the dam inventory after it breached in 1999. It was rebuilt without the knowledge of the NE DNR. A downstream two-lane state highway was washed away.
