Piney Branch is a tributary of Rock Creek in Washington, D.C. It is the largest tributary located entirely within the Washington city limits.
Located in the Northwest quadrant of Washington, D.C., the stream flows next to Piney Branch Parkway and empties into Rock Creek near the intersection of the parkway and Beach Drive, inside Rock Creek Park. Rock Creek drains to the Potomac River, which empties into the Chesapeake Bay. [1]
Piney Branch is a first order stream (i.e., no tributaries) with a surface length of 0.75 miles (1.21 km). It is generally about 12 feet (3.7 m) wide and 4 inches (10 cm) deep. It is the largest tributary located entirely within the Washington city limits. [2]
Piney Branch drains a watershed of 0.48 square miles (1.2 km2).[ citation needed ] Its surface stream drainage is augmented by four combined sewer systems that discharge into it. About five percent of the watershed consists of forested parkland near its surface stream. The rest of the area is mainly residential, with some light industrial zones. The creek is listed as polluted by 10 chemicals and four metals: lead, copper, zinc, and arsenic. [2] It is spanned by the 16th Street Bridge, the country's first parabolic arch bridge.
In prehistoric times, the creek's valley was a source of quartzite cobbles for toolmaking. One quarry site is located at the bluffs overlooking Piney Branch from the north, about 30 feet below the summit of a southeast-facing hill. Dubbed the "Piney Branch Quarry Site", it was first examined by archeologist William Henry Holmes in 1889 and 1890. Another investigation begin in 2006 revealed quartzite debitage, whole and broken turtleback “preforms,” and half of a large ax. [3]
In the mid-1800s, the creek's valley was the location of the first road through the area that would become Rock Creek Park. Called Piney Branch Road or 14th Street Road, the narrow country way went north from the Mount Pleasant neighborhood down into the valley, across a rickety bridge just west of today's 16th Street Bridge, then climbed up to the present-day neighborhood of Crestwood. [4]
Funding to build the Piney Branch Parkway, which runs along the creek for most of its length, was "authorized in 1907, but not built until the mid-1930s when funding and workers became available through the New Deal." [4]
In 2014, the District of Columbia Water and Sewer Authority began design work on the Piney Branch Trunk Sewer Rehabilitation Project, a series of repairs and improvements to the combined sewer system that discharges into the creek. Composed of 8- to 10-foot brick and concrete pipes, the Piney Branch Trunk Sewer is one of the city's major trunk sewers. Project design was slated to start in January 2014 and last one year. As of early 2016, work was to begin in 2017 and last until 2019. [5]
Rock Creek Park is a large urban park that bisects the Northwest quadrant of Washington, D.C. The park was created by an Act of Congress in 1890 and today is administered by the National Park Service. In addition to the park proper, the Rock Creek administrative unit of the National Park Service administers various other federally owned properties in the District of Columbia located to the north and west of the National Mall, including Meridian Hill Park on 16th Street, N.W., the Old Stone House in Georgetown, and certain of the Fort Circle Parks, a series of batteries and forts encircling the District of Columbia for its defense during the U.S. Civil War.
The Anacostia River is a river in the Mid Atlantic region of the United States. It flows from Prince George's County in Maryland into Washington, D.C., where it joins with the Washington Channel and ultimately empties into the Potomac River at Buzzard Point. It is about 8.7 miles (14.0 km) long. The name "Anacostia" derives from the area's early history as Nacotchtank, a settlement of Necostan or Anacostan Native Americans on the banks of the Anacostia River.
The Patapsco River mainstem is a 39-mile (63 km) river in central Maryland that flows into the Chesapeake Bay. The river's tidal portion forms the harbor for the city of Baltimore. With its South Branch, the Patapsco forms the northern border of Howard County, Maryland. The name "Patapsco" is derived from the Algonquian pota-psk-ut, which translates to "backwater" or "tide covered with froth."
Sligo Creek is a free-flowing tributary of the Northwest Branch of the Anacostia River in Maryland. The creek is approximately 9.1 miles (14.6 km) long, with a drainage area of about 11.6 square miles (30 km2).
Rock Creek is a free-flowing tributary of the Potomac River that empties into the Atlantic Ocean via the Chesapeake Bay. The 32.6-mile (52.5 km) creek drains about 76.5 square miles (198 km2). Its final quarter-mile is affected by tides.
Conococheague Creek, a tributary of the Potomac River, is a free-flowing stream that originates in Pennsylvania and empties into the Potomac River near Williamsport, Maryland. It is 80 miles (129 km) in length, with 57 miles (92 km) in Pennsylvania and 23 miles (37 km) in Maryland. The watershed of Conococheague Creek has an area of approximately 566 square miles (1,470 km2), out of which only 65 square miles (170 km2) are in Maryland.
Cabin John Creek is a tributary stream of the Potomac River in Montgomery County, Maryland. The watershed covers an area of 26 square miles (67 km2). The headwaters of the creek originate in the city of Rockville, and the creek flows southward for 10.9 miles (17.5 km) to the Potomac River.
Difficult Run is a 15.9-mile-long (25.6 km) tributary stream of the Potomac River in Northern Virginia in the United States. The area has had many historical uses dating back to the early 1800s. Today, the area is used recreationally by visitors interested in the watershed's variety of options including hiking, biking, fishing, boating, climbing, and bird watching. The wildlife at Difficult Run is vast as 163 different species can be seen depending on the season. There are 41 different soil types found on the trail and alongside the stream. The stream is part of the greater 57.7- square-mile Drainage basin, or watershed, located in the north-central portion of Fairfax County and drains directly to the Potomac River.
Clear Creek is a stream in northeast Atlanta that is a tributary to Peachtree Creek and part of the Chattahoochee River watershed. It has two main branches, one originating east of the high ground along which Boulevard runs and another to the west originating on the northeast side of downtown Atlanta. The easterly branch of Clear Creek begins in several springs and branches in what are now Inman Park and the Old Fourth Ward. Flowing north, the creek was joined by other branches and springs, including Angier Springs near the end of Belgrade Avenue and the so-called Ponce de Leon Springs, which were “discovered” during railroad construction in the 1860s and gave rise to the eponymous park and avenue.
Oxon Creek is a stream on the Potomac River which feeds a cove that straddles the border between Washington, D.C., and Prince George's County, Maryland just north of Interstate 495 at Woodrow Wilson Bridge. Oxon Creek heads at the confluence of Oxon Run and Barnaby Run, sometimes referred to as Winkle Doodle Run. It starts just inside the boundary of D.C. and then runs 1.5 miles (2.4 km) to the south and west into Maryland to empty into the Potomac at Goose Island across from the city of Alexandria, Virginia. Before reaching the Potomac, the creek widens to form Oxon Cove which is partially in Maryland and partially in Washington, D.C. The creek is almost entirely within Oxon Cove National Park, except for the first few feet in D.C. and a portion of the cove on the southside of the Blue Plains Advanced Wastewater Treatment Plant.
Little Falls Branch, a 3.8-mile-long (6.1 km) tributary stream of the Potomac River, is located in Montgomery County, Maryland. In the 19th century, the stream was also called Powder Mill Branch. It drains portions of Bethesda, Somerset, Friendship Heights, and Washington, D.C., flows under the Chesapeake and Ohio Canal (C&O), and empties into the Potomac at Little Falls rapids, which marks the upper end of the tidal Potomac.
The Anacostia Tributary Trail System (ATTS) is a unified and signed system of stream valley trails joining trails along the Anacostia tributaries of Northwest Branch, Northeast Branch, Indian Creek and Paint Branch with a trail along the Anacostia River, set aside and maintained by the Maryland-National Capital Park and Planning Commission (M-NCPPC) in the Maryland suburbs of Washington, D.C.

It winds for 28 miles (45 km) through the Nashville suburbs of Belle Meade and Forest Hills and eventually flows into the Cumberland River near Rock Harbor Marina at the end of Robertson Avenue. This is one of at least five streams by the name of "Richland Creek" in various regions of Tennessee.
Tanner Creek is a small tributary of the Willamette River in Portland in the U.S. state of Oregon. Named after a tannery owned by one of the city's founders, it begins in what is now the Sylvan–Highlands neighborhood in the Tualatin Mountains west of downtown. In the 19th century the creek flowed on the surface, running northeast across the city, past what later became Providence Park and into a shallow lake and wetlands in what became the Pearl District, bordering the river.
Tibbetts Brook, originally Tippett's Brook or Tibbitt's Brook, is a stream in the southern portion of mainland New York, flowing north to south from the city of Yonkers in Westchester County into the borough of the Bronx within New York City. Originally emptying into Spuyten Duyvil Creek as part of the Harlem River system, the stream is now partially subterranean, ending above ground at the south end of Van Cortlandt Lake within Van Cortlandt Park. There it proceeds into city sewers, draining into either the northern end of the Harlem River or the Wards Island Water Pollution Control Plant. The brook provides significant watershed to both Van Cortlandt Park at its south end and Tibbetts Brook Park at its north end. There have been modern proposals to daylight the southern portion of the brook back onto the surface.
Euclid Creek is a 43-mile (69 km) long stream located in Cuyahoga and Lake counties in the state of Ohio in the United States.
