National Dam Inspection Program. New Holland Reservoir Dam (NDI Number PA-00346, DER Number 36-241), Susquehanna River Basin, Lancaster County, Pennsylvania. Phase I Inspection Report.
Abstract
The New Holland Reservoir Dam is a zoned earthfill structure with a 28.5 foot long concrete ogee type spillway (see Plate IV and V, Appendix F). The dam embankment has a top width of 20 feet, an overall length of 510 feet and is 38 feet high. The spillway is located at the right end of the embankment and discharges into a 'U' shaped concrete channel. This channel has varying widths along its length (Refer to Plate IV, Appendix F). The spillway channel is about 300 feet in length and terminates at the existing stream channel. The dam embankment has a select fill impervious core which rests on the bedrock surface. A concrete cutoff wall extends over the entire length of the embankment. It extends two feet into the rock and varies in the vertical dimension into the embankment core, according to the original ground contour. The rock foundation, below the core wall, was grouted to provide an impervious curtain within the rock mass.
