Conestoga Navigation Company. A slackwater canal between Lancaster and Safe Harbor, built following the company's incorporation in 1825, facilitated access to Philadelphia, Baltimore, and other ports. This canal's 18-mile course included nine sets of locks and dams; Lock No.1 was here. The company's name varied after 1837; financial problems mounted, and last lock fees were collected in 1872. Later, between 1913 and 1946, surviving dams were used to generate electricity.
