National Dam Inspection Program. Brookville Water Works Dam (NDI ID Number PA-422, DER ID Number 33-3) Ohio River Basin, North Fork Creek, Jefferson County, Pennsylvania. Phase I Inspection Report
Based on the evaluation of the existing conditions, Brookville Water Works Dam was found to be in good condition and adequately maintained. The flood discharge capacity of the dam was evaluated according to the recommended procedure and was found to pass less than the 100-year flood without overtopping the embankment portion of the dam. The recommended spillway capacity range is between the 100-year flood and 50 percent of the probable maximum flood (PMF). Considering the low downstream damage potential, the lower limit of the recommended spillway capacity range was considered to be applicable to this dam. Therefore, the flood discharge capacity is classified to be inadequate. However, considering that the slopes of the earth embankment are protected with riprap and the dam has a concrete core wall, and further that the dam has withstood overtoppings in the past without breaching, overtopping of the earth embankment during the passage of 100-year flood can be permitted. Therefore, enlargement of the spillway is not considered to be justified. (Author)
