Record drawings for the repair project indicate that the dam crest dropped approximately 16 feet and the failed section resembled a typical rotational downstream slope failure with mobilized material deposited at the downstream toe. This knowledge, coupled with the recently observed and documented embankment movement near station 4+00, generated sufficient concern about the stability of the dam to warrant immediate action by the dam owner and implementation of a focused long-term monitoring program. The construction was initially completed using the hydraulic fill method, however the construction method was modified to replace the sluice delivery system with side dumping from tracked rail cars into the semi-liquid embankment material. The most significant revelations included the four downstream slope failures, the hydraulic fill construction method used to construct the dam, the suspicion that open remnant coal mine tunnels may extend through the foundation, the poorly abandoned outlet works pipe extending through a portion of the dam, and identification of the foundation bedrock as the Laramie Formation.
