The '''Potomac River''' is located on the east coast of the [[United States]], and runs through [[Maryland]], [[Virginia]], [[West Virginia]], and [[Washington, D.C.]] before it empties into the [[Chesapeake Bay]]. It is over 380 miles long and wider than 11 miles at its widest point.<ref>http://www.potomacriver.org/about_potomac/about_the_potomac.htm</ref>
"The [[Swamp]]" as a pejorative nickname for bureaucrats who fill federal government buildings there is based on the formerly mosquito-infested climate there associated with the Potomac River.
The Potomac River had enormous strategic importance during the [[Civil War]], and was central to the [[Battle of Antietam]] in 1862.
