rdf:langString Swains Lock (Lock 21) and lock house are part of the 184.5-mile (296.9 km) Chesapeake and Ohio Canal (a.k.a. C&O Canal) that operated in the United States along the Potomac River from the 1830s through 1923. It is located at towpath mile-marker 16.7 near Potomac, Maryland, and within the Travilah census-designated place in Montgomery County, Maryland. The lock and lock house were built in the early 1830s and began operating shortly thereafter. Swains Lock is named after Jesse Swain and his family. Jesse Swain was lock keeper for Lock 21 beginning in 1907, and had been a canal boatman. His father had helped with the canal construction, and his grandson has lived in the house and operated an onsite concession stand into the 21st century. Some of the Swains from Jesse's generation were born on canal boats, and more recent Swains were born in the lock house. Family members lived in the house until 2006, when the house was turned over to the National Park Service. Today, the lock and restored lock house are part of Chesapeake and Ohio Canal National Historical Park. Picnic tables at the lock site are located between the Potomac River and the lock house. The lock house is one of seven lock houses on the canal that can be used for overnight stays. It is only a few miles upriver from the Potomac River's Great Falls, and is a few miles downriver from a bird sanctuary.
