National Dam Inspection Report. Boyertown Reservoir Dam (NDI-PA 00707) (PA DER 6-344) Delaware River Basin, Popodickon Creek, Berks County, Pennsylvania. Phase I Inspection Report,

Boyertown Reservoir Dam is an earth and rockfill embankment with a concrete corewall and a 20-foot wide, broad-crested, concrete spillway. The upstream portion of the dam is rolled earth embankment; the downstream section is earth and rockfill. The dam is approximately 620 feet long with a maximum height of 55 feet and impounds a reservoir with a normal pool storage capacity of 105 acre-feet. The dam is located on Popodickon Creek and serves as a source of water supply for Boyertown, which is situated approximately 2.5 miles downstream (east) of the dam. The Spillway Design Flood (SDF) for this 'Intermediate' size, 'High' hazard dam is the Probable Maximum Flood (PMF). The spillway is capable of discharging 37 percent of the PMF without overtopping of the embankment. The spillway is classified as 'Inadequate'. The spillway is not classified as 'Seriously Inadequate' because the depth and duration of overtopping are not considered sufficient to cause a failure of the embankment at 50 percent of the PMF. Based on the visual observations and review of the information obtained from the Pennsylvania Department of Environmental Resources, Division of Dam Safety, Boyertown Dam is considered to be in good condition.
