Question: Which canal is located in Washington D.C, Washington City Canal or Beardsley Canal?
Context: Beardsley Canal is an irrigation canal in Kern County, California.  It originates for the Kern River, east of Gordon's Ferry and just west of the First Point of Measurement.  It is the first diversion from the river in the San Joaquin Valley for agriculture irrigation (Hart Park has two canals, but are used exclusively for aesthetics and reconnect to the river).  It terminates at reservoirs located in Famoso, just east of SR 99 (Golden State Freeway). Tiber Creek or Tyber Creek is a tributary of the Potomac River in Washington, D.C. In the 19th century it was modified to become part of the Washington City Canal, and subsequently was enclosed in a tunnel. Tiber Island was a man-made island in Washington, D.C. formed when the Washington City Canal was dug to connect the stream beds of Tiber Creek and James Creek, creating an island out of an existing peninsula southwest of the Capitol.  The canals have since been filled in, rejoining the island to the mainland.  The Southwest Waterfront, Buzzard Point, National Mall, and L'Enfant Plaza areas were once on the island; at that time, their isolation from "the mainland" led to the area's colloquial nickname as "The Island." The Brandenburg City Canal, or Brandenburger Stadtkanal in German, is a canal in the German state of Brandenburg.  It provides a 4 km route through the centre of the city of Brandenburg an der Havel. The Union Bay Natural Area (UBNA) in Seattle, Washington, also known as Union Bay Marsh, is the restored remainder of the filled former Union Bay and Union Bay Marsh after University Village Shopping Center, the University of Washington (UW) athletic facilities, buildings, and main parking area (E1).  It is located at the east end of the main UW campus, south of NE 45th Street and west of Laurelhurst.  Ravenna Creek is connected to University Slough (Drainage Canal), thence to Union Bay, and Lake Washington.  Drainage Canal is one of three or four areas of open water connected with Lake Washington around Union Bay Marsh.  The canal extends from NE 45th Street, between the driving range and IMA Sports Field 1, south to the bay, ending southeast of the Husky Ballpark baseball grandstand (northeast of the IMA Building).  The Drainage Canal that carries Ravenna Creek past UBNA to Union Bay is locally sometimes called University Slough, though that is something of a misnomer in that "slough" is both used in the eastern and southeastern U.S. meaning, rather than the western U.S. meaning, and it is no longer a natural watercourse in that it is a canal that replaced bay and marsh, both now filled. The Washington City Canal operated from 1815 until the mid-1850s in Washington, D.C. The canal connected the Anacostia River, called the "Eastern Branch" at that time, to Tiber Creek, the Potomac River, and later the Chesapeake and Ohio Canal (C&O).  The canal fell into disuse in the late 19th century and the city government covered over or filled in various sections. The City Canal was a short, and short-lived, canal excavated across the Isle of Dogs in east London, linking two reaches of the River Thames.  Today, it has been almost completely reconstructed to form the South Dock of the West India Docks. The Shamiram canal also known as Semiramis canal previously Menua canal is a canal located east of Van that runs 45 miles long supplying a large region.  King Menua built the Semiramis canal, according to his inscriptions, which are still visible by the canal.  Menua's canal, which brought fresh water to the capital city of Tushpa, has survived to the present day and is known to the people of the Van region as the "canal of Semiramis,". The Jordan and Salt Lake City Canal is an historic waterway in Salt Lake County, Utah.  It was first envisioned in 1849 and construction began in 1855.  Initially conceived as a way to transport granite blocks from a quarry in Little Cottonwood Canyon to the construction site of the future Salt Lake Temple (a railroad spur from the canyon to the temple grounds was completed before this could become a reality), the canal evolved into a typical irrigation waterway. Lake Union is a freshwater lake entirely within the Seattle, Washington city limits and a major portion of the Lake Washington Ship Canal.  Its easternmost point is the Ship Canal Bridge, which carries Interstate 5 over the eastern arm of the lake and separates Lake Union from Portage Bay.  Lake Union is the namesake of the neighborhoods located on its east and west shores: Eastlake and Westlake, respectively.  The northern shore of the lake is home to Gas Works Park.  Notable features of the southern portion of the lake—collectively known as the South Lake Union district—include Lake Union Park, Museum of History & Industry (MOHAI), and the Center for Wooden Boats.
