National Dam Inspection Program. Mosquito Run Dam (NDI Number PA01012, PennDER Number 41-2), Susquehanna River Basin, Mosquito Creek, Lycoming County, Pennsylvania. Phase I Inspection Report
Abstract
Mosquito Run Dam is owned by Williamsport Municipal Water Authority and is classified as a 'Significant' hazard - 'Small' size dam. The dam was found to be in good overall condition at the time of inspection. 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 Mosquito Run Dam. Because the dam is on the low end of the 'Small' size category in terms of height and storage capacity, the 100-year flood was chosen as the SDF. Hydraulic/hydrologic evaluations, performed in accordance with procedures established by the Baltimore District Corps of Engineers, for Phase I Inspection Reports, revealed that the spillway capacity is greater than the inflow to the impoundment during the 100-year flood. The spillway is therefore considered 'Adequate.' The inspection revealed certain items of remedial work which should be performed by the owner without delay.
