National Dam Inspection Program. Miller's Pond Dam (NDI Number PA 01004, PennDER Number 8-27), Susquehanna River Basin, Miller's Run, Bradford County, Pennsylvania. Phase I Inspection Report
Miller's Pond Dam is owned by Ernest Weaver and is classified as a 'Low' hazard - 'Small' size dam. The dam was found to be in poor overall condition at the time of inspection. Hydraulic/hydrologic evaluations revealed that the spillway will pass the 100-year flood without overtopping the dam. A spillway design flood (SDF) in the range of the 50-year flood to the 100-year flood is required for Miller's Pond Dam. The 100-year flood was chosen as the SDF. Therefore, the spillway is considered 'Adequate'. There are two seeps, approximately 5 g.p.m. and 1 g.p.m., and a minor boil near the downstream toe of the dam. There are depressions along the upstream crest which may indicate 'piping' of the embankment materials. These ares should be monitored. Several items of remedial work should be immediately initiated by the owner. These include: (1) Monitor the two areas of seepage at regular intervals and during periods of high reservoir levels for turbidity and/or increase in flow, which may indicate the potential for piping of embankment material. If turbidity or increased flows are noted, a qualified geotechnical engineering firm should be retained to recommend remedial measures. (2) Fill, compact, and seed the depressions on the crest of the dam. (3) Cut all trees and brush on the embankment at ground level. (4) Clear the spillway approach channel of all debris and protect with riprap. (5) Repair the discharge apron and training walls. (6) Fill and seed the areas of erosion behind the wingwalls. (7) Protect the channel immediately downstream from the embankment with erosion protection. (8) Provide means to draw down the reservoir during an emergency.
