National Dam Inspection Program. K-Section Dam (NDI ID Number PA-1045, DER ID Number 1-84), Potomac River Basin, Tributary to Toms Creek, Adams County, Pennsylvania, Carroll Valley Borough. Phase I Inspection Report
The assessment of the K-Section Dam is based upon visual observations made at the time of inspection, review of available records and data, hydraulic and hydrologic computations and past operational performance. The K-Section Dam appears to be in good condition and adequately maintained. No major deficiencies were observed during the inspection which were considered as significantly affecting the stability of the structure. Minor erosion areas were observed adjacent to the right spillway approach and discharge channel walls. No seepage was observed during the inspection. A wet area was observed along the downstream toe of the dam. No control exists for the 24 in. drainline through the embankment. A piece of plywood has been bolted to the end of the pipe at the outlet. The K-Section Dam is a low hazard-small size dam. The recommended spillway design flood (SDF) for a dam of this size and classification is in the range of the 50-year storm to the 100-year storm. No homes or structures were observed in the potential flood wave associated with a dam failure. It should be noted that future development downstream of the dam could increase the hazard classification of the dam. A change in the hazard classification would warrant the formulation of an emergency action plan to warn downstream residents of imminent failure of the dam. The spillway design flood has been selected as the 100-year storm. The spillway and reservoir are not capable of controlling the 100-year storm. Therefore, the spillway is rated as inadequate.
