The Potomac River flows across four states and Washington, DC. It drains 14,670 square miles, crosses five geological provinces and flows a distance of 383 miles. It originates at Fairfax Stone in West Virginia as a small stream, but grows as each of its tributaries add their waters to it - including the Anacostia River, Antietem Creek, Cacapon River, Catoctin Creek, Conocoheague Creek, Monococy River, Occaquan River, Savage River, Seneca Creek and the Shenandoah River. The Potomac River basin is 57.6% forest, 31.8% agriculture and 4.8% developed. In addition to the 184.5 miles of riverfront property that the C&O Canal National Historical Park protects, there are several other local, regional, state, and national parks along the Potomac River.
This river affects everyone who lives in its drainage on a daily basis. 486 million gallons of water are withdrawn daily. The Potomac River supplies 90% of Washington, DC and northern Virginia residents with their drinking water. Sometimes it is hard to believe that the Potomac River is surrounded by so many people. Another 100 million gallons of ground water in the watershed are withdrawn in rural areas on a daily basis.
Just as the river effects people who live within its watershed, people effect the river as well. Dams provide people with water and power, change the river's natural hydrology, and prevent the migration of shad and other fish. The Potomac River is impacted by runoff from individual homes, roads, storm drains, construction sites, agricultural fields, and industry. Fertilizers, herbicides, insecticides, oils, animal waste, and soil erosion can cause even more damage than physical trash.
Recently, we as a society have become more aware of the impacts we are having on the environment, and the health of the Potomac River has improved. Regulations have banned several practices that were especially harmful, including the use of DDT. Fish ladders were built around most dams to accommodate migrating shad. Annual watershed-wide cleanups have been occurring for 23 years. In 2011 alone, 11,388 Volunteers removed 228 tons of trash from the Potomac River.
In 2001, the National Park Service partnered with the Potomac Conservancy to help protect the Potomac River and educate people living within its watershed. The River Center was opened by the Conservancy in Lockhouse 8 in 2004. It is open weekends May- September.
I encourage you to visit Lockhouse 8 and the River Center. My favorite exhibit is "Backyard to the Bay," which looks at the natural diversity and scenic beauty of the Potomac River, as well as the effects of human activities on the health of the ecosystem.
Also, please take the time to enjoy the river itself. Do not wade or swim in the Potomac. Even when it looks placid, it has an uneven bottom and dangerous undertow. Instead, walk along its edge, fish from its banks, or kayak out into its waters. You may be surprised that you, like George Washington and me, find yourself falling in love with the mighty Potomac River.
