Schuylkill Navigation Company

The Schuylkill Canal was not a continuous canal, but a series of waterways constructed to bypass unnavigated sections of the river. The Schuylkill navigation system covered a distance of 108 miles; 62 miles by canal and 46 miles by slack water navigation created by dams in the river. The system included 92 locks to overcome a 9,588' difference in elevation. Locks were typically 75' to 80' long and 8' to 17' wide. By 1828, the Schuylkill Canal provided safe passage the length of the river. In the early years, there was no effective competition to the canal and rates were high. As a result of this monopoly, the State Legislature authorized construction of the Reading Railroad.



On January 13, 1842, the Philadelphia and Reading Railroad was opened to Pottsville in direct competition to the canal and by 1844, it carried more coal than the canal. To meet the railroad competition, the canal was enlarged, and costs were lowered. Tonnage increased as a result and the period 1850-1860 marked the Golden Age of the Canal. During this period, the canal showed the greatest profit and carried the greatest tonnage, peaking at 1.7 million tons.


Rail transportation assumed increasing importance during the Civil War; after the war, railroads continued to grow, and canal transportation declined. On June 23, 1870, the Reading Railroad signed an agreement to lease the canal and from this time on commercial use of the canal virtually ceased.
