Towpath Temporary Closures
7/9/14- 4pm, Many towpath sections still remain closed due to the storm. This include MP98 to MP76 and MP162 to MP144. Crews will be working again tomorrow to continue clearing the towpath. Please use caution and stay clear of tree clearing crew
6/14/14- Towpath breach at MM 106, just below Dam #5. Towpath Detour in place (this detour does not leave park property). Please be aware of possible towpath hazards due to heavy rains.
Water Pump Handles Temporarily Removed
Purslane Run, Stickpile, Evitts Creek Hiker-Biker Campgrounds and Paw Paw Campground water pump handles have been removed due to bad water samples. Handles will be installed when good water samples are received.
Parking Lot Closure
CSX is now beginning a phase of their bridge project that requires the closure of the Lock 74 parking lot for approximatly 18 months. Access to visitor parking near Lock 75 is now re-opened with a gravel parking lot at the site.
Boat Rides at Great Falls
Regularly scheduled tour times for the mule-drawn canal boat at Great Falls have changed. In July and August 2014 tours will be offered Saturdays and Sundays at 11:00, 1:30 and 3:00. Please call the Visitor Center for more info: 301-767-3714. More »
The Incline Plane
The Chesapeake and Ohio Canal originated out of concerns to open up a better transportation route to the west. From its inception, the canal struggled to become a profitable enterprise. Many things, including a competing new form of transportation, the railroad, added to the toil. Finally, in the 1870’s, the canal began to turn a profit bringing with it new problems to the C&O Canal.
To encourage the growth of the canal as a profitable enterprise, the Canal Company encouraged more boats to ply its waters. In its brief "heyday" the canal boasted of over 540 boats in operation. This enormous jump in the number of vessels on its water brought about the earliest "gridlock" to the Washington D.C. area. Captains were finding they had to tie up further and further from Georgetown, encountering longer and longer delays. Sitting in traffic today along the "beltway" encircling D.C. it is not unusual to encounter two-hour back-ups. Back in the 1870’s, it was beginning to take two days to get into Georgetown from two miles away. The frustration they were feeling is understandable when linked to our transportation "gridlock" that is complicating travel in most every major city in the U.S. The boatmen, like most of us today, were always eager to avoid delays. As often happens, frustration led to solution.
Georgetown was not the final destination for every boat. Many boats simply needed to go through Georgetown to access to the Potomac River at the tidelock. The Canal Company realized that if those boats could somehow bypass Georgetown it would speed up the trip for the boats that were heading there.
The finished product was a caisson into which a boat would float. The boat, inside the caisson, would travel on the rails of an inclined plane from the canal and descend into the river. It was balanced by two counterweights and powered by a turbine supplied with waterpower from the canal. The turbine would turn the grooved pulleys through which the cables passed that were connected to the caisson and counterweights. The counterweights were wooden frames that were filled with stone weighing 200 tons each.
Upon its completion, the structure was the largest of its kind in the world and duly gained acclaim as an engineering marvel. A scale model of it was displayed at the 1878 Paris Exposition. Nearly as soon as it went into operation, however it became non-essential. Transportation on the Chesapeake and Ohio Canal rapidly declined in the following decade. Seriously damaged during a flood in 1889, the incline plane was never put back into service.
Today, little remains of this early engineering marvel. A small wayside exhibit stands at mile 2.26 as a memory of the ongoing efforts of Americans to overcome obstacles, even the obstacles we created.
Did You Know?
George Washington's dream of connecting the eastern states with the western frontier led to the creation of the Patowmack Company. Canals were built around unnavigable parts of the Potomac River for improved commerce. The C&O Canal inherited the right of way after the Patowmack Company's demise. More...
