Inscription.
The Potomac River and nearby Rock Creek meet quietly here at Tide Lock.

Years ago, canal boats locked into Rock Creek from the C&O Canal about a half-mile upstream and then through Tide Lock into the bustling world of the Potomac waterfront. Coal, building stones, and other cargo were unloaded at busy wharves or transferred to schooners and steamships. A skirting canal along the river bank led to the Washington City Canal which followed what is now Constitution Avenue to wharves on the Anacostia River.

Though few signs remain of its heyday, the Georgetown riverfront once livened to the shouts of sailors, canallers, longshoremen, and the impatient braying of canal mules tethered near the present-day Thompson’s boat house.
