Washington City Canal
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.
In the early years of the United States there was great interest among political leaders in building canals to support and stimulate economic development. Construction of a canal to run across the city of Washington was supported by local leaders, both in business and government.  The plan was to connect the Eastern Branch, which was navigable into Maryland, with the Potomac, which was seen as a gateway to the West. President George Washington had founded the Potowmack Company in 1785 to improve navigation on the Potomac.
Pierre (Peter) Charles L'Enfant, in designing a master plan for the development of the capital city, supported construction of a canal between Eastern Branch and Tiber Creek.  To raise funds for canal construction, lotteries were conducted in 1796, but these efforts were unsuccessful. There was little additional work done until 1802, when Congress granted a charter for the Washington Canal Company. A small amount of construction was started, but obtaining major financing for the canal continued to be difficult.
Congress created a new canal company in 1809 and authorized capitalization of $100,000. A groundbreaking ceremony in southeast Washington, attended by President James Madison and other officials, took place on May 2, 1810. Construction was delayed by the War of 1812 and resumed in 1815.
The canal formally opened in late 1815.  The canal route began at the Eastern Branch, near the Washington Navy Yard and proceeded north and northwest. Another branch proceeded north and northeast from the estuary of James Creek, which divided Greenleaf Point from Buzzard Point.  Past the point at which these two branches converged, a single canal channel travelled north towards the Capitol, veered northwestward at the base of Jenkins Hill ( Capitol Hill), and then turned again to the north to cross the area in which the National Mall is now located. The canal then turned sharply to the west, joining a straightened and channelized Tiber Creek, which had earlier flowed westward. After traveling westward along the route of Tiber Creek, the canal entered the Potomac River at the mouth of the creek, which was south of the White House.
As originally built, the Washington City Canal was shallow and only accommodated boats drawing 3 feet of water or less. The canal's design did not adequately handle tidal variations on the Eastern Branch. As a result, the canal sometimes overran its banks at high tide, and/or experienced insufficient water levels at low tide. Traffic through the canal continued but financial problems persisted, and in 1831 the city purchased the canal corporation. The city effected some repairs during the 1830s and Congress appropriated some additional funds in 1833.
Also in 1833, an extension of the C&O Canal was completed. That extension, designated as the Washington Branch of the C&O Canal, enabled the C&O Canal to connect at a new eastern terminus with the western terminus of the Washington City canal at the mouth of Tiber Creek.    A lock was built to connect the two canals, and around 1835, a lock keeper's house was built. The lock keeper's house now stands at the southwest corner of Constitution Avenue, Northwest (N.W.), and 17th Street, N.W., near the National Mall.  
In 1849, Congress appropriated some additional funds to clean out and deepen portions of the canal, on the condition that the city provide matching funds. The city made some improvements to the canal, but it experienced problems with contractors and staff, and the planned work was not completed in the 1850s. During this period, with the increasing development of railroads, interest in canals waned among both business and government leaders.
By the late 1850s, the Washington City Canal had fallen into disuse, as had the Washington branch of the C&O Canal. During the Civil War years the canal deteriorated further and was serving as both a sewer and storm drain system for the central part of the city. Various proposals were circulated to either rehabilitate the city canal or fill it in. Congress appropriated some funds in 1866, but no work was done at that time. In 1871, Alexander "Boss" Shepherd, the city's head of Public Works, directed that the Tiber Creek portion of the canal be covered over. This work was accomplished over many years, along with other drainage alterations in the central city. A new street that was constructed over this portion of the canal was initially designated as B Street, N.W. The street was later renamed to Constitution Avenue, N.W.
The southern portion of the Washington City Canal remained open for years afterwards, but eventually was also paved over. A street constructed south of the Capitol over that section of the canal now connects Independence Avenue, Southwest, and E Street, Southeast. Formerly designated as Canal Street, the northernmost section of the street was later renamed to Washington Avenue in commemoration of the state of Washington.
