National Dam Inspection Program. Marshwood Dam (NDI ID Number PA-00365, DER ID Number 35-88), Susquehanna River Basin, Little Roaring Brook, Lackawanna County, Pennsylvania. Phase I Inspection Report
Marshwood Dam is two homogeneous earthfill embankments with masonry core-walls. The dam was built in a natural saddle. The embankments impound water within the saddle. The dam has a main spillway and an auxiliary spillway. The main spillway is located at the right abutment of the South Embankment. It has a sharp-crested concrete weir with a crest length of 100 feet. The auxiliary spillway is a canal about 300 feet left of the South Embankment. Based on visual inspection, available records, calculations and past operational performance, Marshwood Dam is judged to be in fair condition. The spillway can pass 65 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. The spillway capacity is rated as inadequate. This rating is dependent on implementation of some of the recommendations herein. If the low areas on the embankments were raised 0.6 foot to the design elevation, the spillway can pass 80 percent of the PMF. The spillway capacity would still be rated as inadequate.
