Abstract:

The condition of Doverspike No. 2 Dam is considered to be good, except that the dam has no outlet works and no formally engineered spillway facilities. A low spot on the crest of the dam located at the junction of the embankment and the right abutment appears to be the intended spillway overflow section. On the dates of inspection, the pool level was found to be approximately 5 feet below the low spot on the crest of the dam, and as reported by the representative of the owner, the pool is normally maintained at that level by seepage and evaporation losses from the reservoir. According to the recommended criteria, intermediate size dams in the significant hazard category are required to pass from 50 percent of the probable maximum flood PMF to full PMF. In view of the downstream damage potential, the lower limit of the recommended range is considered to be applicable to this dam. The flood discharge capacity was evaluated according to the recommended procedure and the dam was found to impound less than 20 percent of the PMF without overtopping the embankment. Therefore, the flood discharge capacity of the dam is classified to be inadequate.
