UPCOMING 2025 EVENTS
celebrating the history of Pennsylvania’s pioneering slackwater-canal system

For more about the project, see below.
June 14-20, 2025: Schuylkill Sojourn. The theme of this year’s sojourn, a weeklong paddle down the river from Schuylkill Haven to Philadelphia, will be “Canals and Campfires,” with evening educational programs about the history of the Schuylkill Navigation. You can sign up for a day, several days or the whole week. Learn more from the sponsor, Schuylkill River Greenways National Heritage Area. Paddlers will also be able to “Adopt-a-Canal-Boat,” with stickers available with names of real boats that once plied the Navigation. You can find stories and images of canal boats and their adoption stickers at this link.

June 26, 2025: Grand Reopening of the Manayunk Canal at Flat Rock.
“The Philadelphia Water Department is excited to announce the Manayunk Canal Reopening Community Event, celebrating the completion of the Flat Rock Dam Betterment Project. Join us to celebrate this major infrastructure improvement for Philadelphia waterways and the re-introduction of fresh water flow into the Manayunk Canal. Attendees can learn about water quality improvements, speak with local partners, and watch a mussel presentation.”
TIME: 11:00 am – 2:00 pm (rain or shine)

LEARN MORE ABOUT THE SCHUYLKILL NAVIGATION
TWO CANALS
Philadelphia has two canals:
The Manayunk Canal, still watered with intact lock chambers at both ends.
The Fairmount Canal, with just a few hidden remnants left.
This 12-page booklet by Fairmount Water Works educator Sandy Sorlien tells the story of both our canals, and the legacy of the associated industries, pollution, and cleanup.
Together these Philadelphia canals didn’t even add up to three miles. But they were critical levels of the 108-mile Schuylkill Navigation that brought anthracite coal and other cargo from Schuylkill County all the way to our tide lock at the Fairmount Dam, some boats continuing on New Jersey canals to New York City. The Navigation canals also provided critical water power to mills.
TWENTY-SEVEN CANALS
The Schuylkill Navigation is often called the Schuylkill Canal. But actually the system included 27 canals, each with its own name, along with 32 dams and their slackwater pools. Thus, 200 years ago, the shallow, rocky Schuylkill River was tamed. Boats up to 100 feet long traveled in and out of the river pools and canals. They brought cargo from coal country to tidewater, and went back up. There were scores of hand-built stone locks to handle the elevation change, totaling 618 feet of “lift”, and aqueducts to carry the canals over streams. The Navigation ceased operation by the 1930s, but many structures survive: some standing in the woods, some buried under fill. One even survives underwater.
The private Schuylkill Navigation Company, based in Philadelphia, chartered their system in 1815. Construction began in 1816, a year before the Erie Canal started their construction. The upper and lower sections of the Schuylkill Navigation were built simultaneously with individual canals operating as early as 1818 or 1819, including the one in Manayunk. The two long sections finally connected through Reading on May 20, 1825.

The shadow image at the top of the page is a detail from an 1847 map of the Manayunk Canal by John Levering, from the collection of the City Plans Unit, Streets Department of Philadelphia. This tracing of the original was made by H. H. Platt, probably in the late 19th century. You can view the full map here.
