Historic Structures Survey, Part I, Historic Data Section - Dam No. 4, Chesapeake & Ohio Canal
Franzen AW. 1964. Historic Structures Survey, Part I, Historic Data Section - Dam No. 4, Chesapeake & Ohio Canal. Historic Structure Report. U.S. Department of the Interior, National Park Service
The purpose of this report is to assemble and study all of the documentary materials that have been located relating to the construction of Dam Number 4 of the Chesapeake and Ohio Canal. The objective is to provide information that will be useful in the restoration, including the rewatering, of the canal through the developing of a physical history of the canal. It was to be used as background material for the eventual interpretation of the structure. A series of dams was constructed along the Potomac to assist with the watering of the canal. Dam Number 4 is approximately 13.7 miles downstream of the town of Williamsport, Maryland. It was used to divert water to the portion of the canal immediately upstream of Harpers Ferry. The first general specification for dams was prepared by the Canal Company in 1828. This includes construction history; details of specifications; correspondence between engineers, contractors, and company directors; and factors that challenged the dam's construction. It also includes photos from various times that show flooding and flood damage, the control structure and stop gate, and repair work after the 1936 flood.
