East Potomac Park is a park located on a man-made island in the Potomac River in Washington, D.C., United States. The island is between the Washington Channel and the Potomac River, and on it the park lies southeast of the Jefferson Memorial and the 14th Street Bridge. Amenities in East Potomac Park include the East Potomac Park Golf Course, a miniature golf course, a public swimming pool (the East Potomac Park Aquatic Center), tennis courts, and several athletic fields (some configured for baseball and softball, others for soccer, rugby, or football). The park is a popular spot for fishing, and cyclists, walkers, inline skaters, and runners heavily use the park's roads and paths. A portion of Ohio Drive SW runs along the perimeter of the park. East Potomac Park is accessible primarily by road via Ohio Drive SW. The DC Circulator National Mall Route, which began service in June 2015, provides the best public transportation option for reaching East Potomac Park. The closest Circulator stop is at East Basin Drive SW south of the Jefferson Memorial, which is within easy walking distance of Ohio Drive SW and the north end of the park. Metrobus does not serve the park, and there is no Washington Metro stop close to the park. The nearest Metro stop is the Smithsonian station at Independence Avenue SW and 12th Street SW, about six blocks away. (Walking from Metro requires accessing the park via Raoul Wallenberg Place SW, Maine Avenue SW, and Ohio Drive SW.) Construction Although the shoreline of the Potomac River in the District of Columbia was likely to have been littered with shoals, sandbars, and marsh flats, no documentation of these was undertaken until 1834. At that time, the United States Army Corps of Topographical Engineers identified extensive tidal flats below Long Bridge (the predecessor structure to the 14th Street Bridge). These varied in size, but the largest was in size at low tide. By 1881, these extended from about the Old Naval Observatory down to Buzzard Point. Near the modern intersection of 17th Street NW and Constitution Avenue NW, the city's sewer system discharged into an extensive tidal flat, known as Kidwell's Meadows. Exposed to the air about half the time, the sewage began decomposing, creating a powerful, rank smell. The southern part of the Pennsylvania Avenue district was flooded many times in the last three decades of the 19th century. Major
