National Dam Inspection Program. Gravel Lick Dam (NDI PA-807), Ohio River Basin, Gravel Lick, Clearfield County, Pennsylvania. Phase I Inspection Report.
Abstract
Based on a visual inspection and available engineering data, Gravel Lick Dam and its appurtenances are considered to be in fair condition. The spillway and dam are capable of passing and/or storing the flow resulting from a storm of PMF magnitude without overtopping the embankment. As a result, the spillway is considered adequate. Seepage through the downstream slope, steadily increasing pore pressures near the downstream toe and erosion below the downstream bench level are apparent. It is recommended that: (1) the owner engage the services of a qualified registered professional engineer to investigate the seepage through the downstream face and evaluate the increasing pore pressure conditions at the toe; (remedial measures should then be implemented as required); (2) the erosion gullies along the downstream face be backfilled and seeded; (3) a formal warning system be implemented to protect those persons downstream who may ultimately be affected by an embankment breach; and (4) the dam should be inspected on a periodic basis to check for hazardous conditions which might develop.
