National Dam Safety Program. Teal Lake Dam (MO-10082), Missouri - Kansas City River Basin. Audrain County, Missouri Phase I Inspection Report
The inspection and evaluation by the consultant's inspection team indicates that the spillway of Teal Lake Dam does not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. Teal Lake Dam being a small size dam with a high hazard potential is required by the guidelines to pass from one-half of the Probable Maximum Flood to the Probable Maximum Flood without overtopping. Considering the number of inhabited dwellings and a school being located within one mile downstream of the dam, the PMF is considered the appropriate spillway design flood for Teal Lake Dam. Other deficiencies noted by the inspection team were: the erosion on the downstream slope and the left abutment due to steep slopes and lack of protective grass cover, lack of adequate protection against erosion of the upstream slope, the small trees observed on the downstream slope, the bulges observed in the two spillway pipes, the two sections of the pipe on the far left side of the spillway which were cut out of the bottom of the conduit and the rusting of the bottom of this pipe, the erosion near the right wingwall of the headwall of the spillway, a need for periodic inspection by a qualified engineer and a lack of maintenance schedule. The lack of seepage and stability analyses on record is also a deficiency that should be corrected.
