The below gives an update on the status of canal repairs and restorationAs Potomac Interceptor repairs continue, we’ll continue daily Potomac River water quality testing through July 31.
Monitoring over the past several months continues to show the Potomac River is within its normal range. As we move into the next phase of environmental rehabilitation with the Maryland Dept. Of The Environment(MDE), cleanup at the C&O Canal is nearly complete.
We expect to complete canal cleanup by mid-July before beginning repairs to the canal lining and restoring the canal and lock structures.

Chesapeake and Ohio canal approaching the site of the Broad Run Trunk Aqueduct, Montgomery County Maryland.
This is a unique spot on the C&O, in that trunk aqueducts were rare.
This was originally built as a double culvert, listed as culvert 44, and the only two span culvert on the entire canal.
The original double culvert was washed out during a flood in 1846, and was hurriedly replaced with a wooden trunk structure. A permanent trunk aqueduct replaced the temporary one in 1856.
All of the wooden timbers that supported this Aqueduct are gone today, and a pedestrian bridge has been erected where the tow path was.

The granary was established in the 1850s, and burned in the 1960s. The foundation remains on the berm side of the canal today, stabilized by National Park Service.
