Tributary Tuesday: Difficult Run (Fairfax County, Virginia)

Like many buildings in Northern Virginia, Fairfax County’s Herrity Building is surrounded by traffic and occupied by government workers. But Herrity also sports a landscaped pond that’s not just a parking lot decoration. It’s the headwaters of Difficult Run, a Potomac River tributary that winds through development-burdened Fairfax County before ending near Great Falls Park, where it’s enveloped in lush vegetation, dotted with boulders and surrounded by scenery that seems straight out of a time period from long ago.

Difficult Run’s health fluctuates dramatically throughout its 15-mile run. In cities like Reston and Vienna, unsustainable land use practices have led to eroding stream banks and poor water quality. At 58 square miles wide, Difficult Run’s watershed is the largest in Fairfax County, which means the waterway is affected by development and pollution that happens very far away from its banks.

Luckily, in other places, forest buffers hug the stream’s edges, helping to keep soil in place, provide wildlife habitat, and shade and cool the water. These forested areas have become a favorite of locals who enjoy walking through the woods.

For an excellent weekend hike or bike ride, follow Difficult Run on a secluded 12-mile trail from Glade Drive in Reston to Great Falls Park. Will Difficult Run be difficult? Rumor has it that the trail is perfect for intermediate bikers and beginner hikers.

What’s in a name?

Perhaps the “difficulty” of Difficult Run lies in reversing the effects of development that has led to pollution in many parts of the stream. Fortunately, Fairfax County and others have begun work to restore this important local waterway. In 2008, the Herrity Building installed a green roof atop its parking garage. This colorful garden of native plants prevents stormwater runoff from carrying oil, trash, auto exhaust and other pollutants from the parking lot into Difficult Run.

Along Difficult Run’s banks, the Virginia Department of Forestry has conducted streamside restoration projects and an outreach effort that now serves as a model for other local stream restoration initiatives in the state.

Watershed Wednesday: Friends of Accotink Creek (Fairfax County, Virginia)

From old box springs to blown-out tires, we’ve all had “problem waste” that’s too big and bulky for curbside disposal. The next option is usually to borrow a friends’ pickup truck and drop off your awkward, heavy or disgusting objects at the local dump. But if you live in Fairfax County, Va., there are only two places where you can legally dump your trash (4618 West Ox Road, Fairfax, and 9850 Furnace Road, Lorton).

Maybe it’s the inconvenience of driving across the county to get rid of “problem waste,” or maybe it’s the fee residents must pay to properly dispose of their trash ($6 for five 32-gallon bags, $9 for six to 10). Whatever the case, some residents are illegally dumping their unwanted appliances, shoes, baby clothes and car parts along Accotink Creek, a 25-mile-long Potomac River tributary.

Friends of Accotink Creek is a Fairfax-based volunteer group dedicated to battling illegal dumping. On weekends from March 31 to April 28, Friends of Accotink Creek will be cleaning different sections of the creek as a part of the greater Potomac Watershed Cleanup. The cleanups are much needed: since April 2007, there have been 166 reported illegal dumping acts in the county, and countless others remain unreported. Students, community members, religious organizations, neighbors and nature lovers will come together to drag abandoned dryers up hills and pull embedded tires out of streams. Interested in helping out? Be sure to bring your muscles!

Who knows – someone else’s trash may become your treasure. Volunteer Olivier Giron is building his master’s thesis around taking photographs of the trash – not because he thinks it’s beautiful, but because he believes the dismal juxtaposition of greenery and rusted metal will help influence people’s dumping behaviors. His website, Let’s Do It, Virginia, shows photos of the discarded trash and encourages other organizations to get involved in World Clean Up 2012.

Illegal dumping is one of the largest problems that Friends of Accotink Creek tackles. But the group also has its hands in a variety of environmental projects to restore and protect Accotink Creek.

Invasive weed removal

Klub Kudzu is Friends of Accotink Creek’s invasive weed removal project. On Wednesdays, volunteers help remove kudzu, a climbing and coiling vine native to Asia. Kudzu has no predators to control its spread in the United States; as a result, it grows quickly, climbing over trees and shrubs and killing them by blocking out sunlight. If you’re free, join Friends of Accotink Creek to help save the creek’s native plants from this invader!

Critter counting (aka stream monitoring)

Volunteers monitor Accotink Creek for macroinvertebrates: worms, clams and other small creatures that live at the bottom of streams. Macroinvertebrate populations indicate the health of streams like Accotink Creek. Join other critter counters at Lake Accotink Park on the second Saturday of March, June, September and December.
