The most complex and ambitious portion of the project was at the Great Falls location, where not only a bypass canal was built but a series of five locks as well. Remnants of this undertaking, now known as the Great Falls Canal and Locks, in northern Virginia, record one of the earliest attempts at canal technology in the United States. The series of five locks compensated for an almost 80 ft (76 ft, 9 in.) elevation drop, a feat made more impressive by the fact that hardly anyone who worked for the Patowmack Co. had ever seen such a structure before. However, a lack of information and expertise about how to build the canal system, as well as overcoming the physical obstacles in the river itself, led to a host of problems for the company, eventually leading to its failure. But for the Patowmack Canal, its construction and existence influenced the design and funding of subsequent American engineering projects. |
