Question: Which city in the Baltimore metropolitan area includes a lake and surrounding park?

<P0-S0> Lake Elkhorn is a 37 acre reservoir located in the Owen Brown area of Columbia, Maryland. <P0-S1>  It is Columbia's third and largest lake. <P0-S2>  Its main features are a small dam and a park with a picnic pavilion and a two-mile (3 km) walking path around the lake. <P0-S3>  The path was built in 1982. <P0-S4>  It is surrounded by a park and townhouses. <P0-S5>  The lake, which was built in 1974, is named for the Elkhorn branch of the Little Patuxent River. <P0-S6>  In 1969, Spiro Agnew proclaimed the arrival of the first Columbia based scientific firm, Hittman Associates that relocated for favorable lease rates from Howard Research and Development. <P0-S7>  Hittman in turn was contracted by the EPA using Wilde Lake as an example to recommend reuse of storm water runoff from all of Columbia's reservoir systems for residential drinking water to save on development costs. <SEP> <P1-S0> The Maryland Crab Bowl is an annual high school football postseason all-star game that features some of the most outstanding players in the state of Maryland. <P1-S1>  The game is played at McDaniel College, between a team composed of players from Washington, D.C. area schools (the "Washington" squad) and one of players from Baltimore and elsewhere in the state (the "Baltimore" squad). <P1-S2>  As an all-star game, it provides high-school players with an additional opportunity to impress college football scouts and may increase their chances of being awarded a university athletic scholarship. <P1-S3>  The Washington team draws from schools in Montgomery County, Prince George's County, and the Southern Maryland Athletic Conference, which includes schools in Calvert, Charles, and St. Mary's counties. <P1-S4>  The Baltimore team draws from schools located elsewhere in the state, primarily in the Baltimore metropolitan area. <SEP> <P2-S0> Falls Road station is a Baltimore Light Rail station in Baltimore, Maryland. <P2-S1>  It is the first stop in surrounding suburban Baltimore County while traveling north from downtown Baltimore. <P2-S2>  The stop is located near the Mount Washington neighborhood in the Jones Falls Valley, and is often used by commuters as a back-up to Mount Washington for parking when the lot at Mt. Washington is full. <P2-S3>  The station is adjacent to Lake Roland Park and Dam (renamed Robert E. Lee Park in the 1940s), constructed in the late 1850s as part of the first segment of the city's new public water supply system in 1860 along the upper Jones Falls stream which flows south through the city emptying into the Inner Harbor of the Patapsco River of Baltimore Harbor and can be viewed from certain parts of the park. <P2-S4>  Although only used for several decades as part of the metropolitan area's public water system until shifting in the 1880s to a larger flowing supply piped from the Gunpowder Falls and construction of the first phase at the Loch Raven Reservoir and its taller Dam. <P2-S5>  Old Lake Roland and Dam are still owned by the City of Baltimore's Department of Recreation and Parks with its surrounding forested watershed, it is now operated and managed by its partner agency, the Baltimore County Department of Recreation and Parks through a recent contract agreement. <SEP> <P3-S0> Columbia is a census-designated place in Howard County, Maryland, United States, and is one of the principal cities of the Baltimore metropolitan area. <P3-S1>  It is a planned community consisting of 10 self-contained villages. <P3-S2>  It began with the idea that a city could enhance its residents' quality of life. <P3-S3>  Creator and developer James W. Rouse saw the new community in terms of human values, rather than merely economics and engineering. <P3-S4>  Opened in 1967, Columbia was intended to not only eliminate the inconveniences of then-current subdivision design, but also eliminate racial, religious, and class segregation.
