National Dam Inspection Program. Yellow Creek State Park Dam (NDI-282), Ohio River Basin, Yellow Creek, Indiana County, Pennsylvania. Phase I. Inspection Report.

摘要

Based on the evaluation of the conditions as they existed on the dates of inspection (September 2 and 8, 1978) and as revealed by visual observations, the condition of Yellow Creek State Park Dam is assessed to be good. Severe erosion of rock was observed along the right wall of the spillway outlet channel, resulting in undermining of the spillway wall foundations. It is recommended that the eroded areas be repaired to avoid structural damage to the walls that may result due to further erosion. Minor rock slides were observed on the right bank of the outlet works discharge channel. The right bank of the outlet works discharge channel should be periodically observed and necessary maintenance performed to prevent blockage of the discharge channel by rock slides. It is also recommended that the outlet conduit sluice gate be repaired to permit adequate seating of the gate. It is further recommended that a formal warning system be developed to alert the downstream residents in the event of emergencies. The spillway capacity is classified to be adequate according to the recommended criteria.
