Abstract:

Based on the evaluation of the existing conditions, the condition of Tuscarora Lake Dam is considered to be fair. Although some deficiencies were observed such as seepage from the toe and lack of upstream erosion protection, none were considered to be significant relative to the overall stability of the dam at this time. Periodic inspection and evaluation of the seepage conditions are recommended. It was found that the dam has no now level outlet facilities. The flood discharge capacity of the dam was evaluated according to the recommended criteria and the spillway was found to pass 10 percent of the PMF without overtopping the low spot of the embankment. This capacity is less than the recommended spillway capacity of 50 percent of the PMF which was based on the size and downstream hazard classification of the dam. Therefore, the spillway capacity is classified to be inadequate.
