National Dam Safety Program. Smith Reservoir Dam. NDI Number PA-00017. PennDER Number 25-28. Lake Erie Basin. West Branch of Sixteen Mile Creek, Erie County, Pennsylvania. Phase I Inspection Report
Smith Reservoir Dam was originally designed (1924) as a 35 foot high earth dam with an emergency spillway excavated in shale in the right abutment. In 1935, the spillway channel was excavated one foot lower and a 2 foot high concrete weir was added to the spillway crest. At the same time the embankment was raised 3 feet. The dam was built for water supply, for which it is still used today. The outlet works consist of two 12 inch cast-iron pipes through the embankment. A valve house is located on the downstream side of the embankment. Both 12 inch pipes can function as blow-offs or supply water into a 24 inch steel pipe leading to the water treatment plant downstream. 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 100-year flood to the 1/2 Probable Maximum Flood (1/2 PMF) is required for Smith Reservoir Dam. The 100-year flood was chosen because the dam is on the low side of the 'Small' size category according to storage capacity. The spillway is therefore considered 'adequate'. The inspection and review of information revealed certain items of work which should be performed immediately by the owner.
