National Dam Inspection Program. Ross Pond Dam (NDI I.D. PA-0265, DER I.D. 058-142), Susquehanna River Basin, Tributary of Drinker Creek, Susquehanna County, Pennsylvania. Phase I Inspection Report
The condition of Ross Pond Dam is considered to be fair. Although at this time no major sign of distress was noted, concerns exist as to the structural adequacy of the dam. As reported by the owner, the embankment material was placed by scrapers in lifts. It appears that no compaction was performed other than rolling of the material by scrapers. It also appears that no laboratory testing, engineering analysis and evaluation, or further testing were performed to assess the adequacy of the fill material for use in an impounding structure. Some surficial sloughs were observed along the downstream slope. Seepage areas were found below the toe of the dam near the left abutment. Flow through the low level outlet pipe is reportedly controlled by an upstream valve submerged in the reservoir. Because the valve is not accessible and its operational condition is uncertain, the dam is not considered to have adequate emergency drawdown facilities.
