dc.descriptionTechnical report-
dc.descriptionPoint Marion Lock and Dam are on the Monongahela River at river mile 90.8, approximately one mile upstream of Point Marion, PA. The reservoir with normal upper pool el 797.0 (elevations (el) are in feet referred to the National Geodetic Vertical Datum) extends approximately 11.2 miles upstream to Morgantown Lock and Dam. The existing Point Marion project consists of a nonnavigable structure with six crest gates having a clear span of 60 ft between 10-ft-wide piers. A 62-ft-long overflow weir with crest el 796.7 connects the gated structure to the right bank abutment. A 56-ft-wide by 350-ft-long navigation lock is located along the left bank of the river. A fixed-bed model reproduced about 2.1 miles of the Monongahela River and adjacent overbank from about mile 90.0 to mile 92.1 with lock and dam structures to an undistorted scale of 1:120. The plan for improvement for Point Marion Lock and Dam consists of a new navigation lock with clear chamber dimensions 84 ft wide by 720 ft long to be constructed landward of the existing lock. The existing lock would be removed and the dam would be connected to the new lock by a 115-ft section comprising a 110-ft-long overflow weir with crest el 796.5 and a 5-ft-long section adjacent to the first dam pier with top el 805.0. A new right bank abutment would replace the present deteriorated structure.-
