Lake Elkhorn is a 37-acre (150,000 m2)reservoir located in the Owen Brown area of Columbia, Maryland. It is Columbia's third and largest lake. 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. The path was built in 1982. It is surrounded by a park and townhouses. The lake, which was built in 1974, is named for the Elkhorn branch of the Little Patuxent River. 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. Hittman in turn was contracted by the EPA using Wilde Lake as a example to recommend reuse of storm water runoff from all of Columbia's reservoir systems for residential drinking water to save on development costs. The lake is overseen by the Columbia Association. The lake's location behind a large number of townhouses, though considered an attractive feature to homeowners, has raised concern following the drowning of a small child on September 2, 2005. A drowning occurred in 1980 and a maintenance worker drowned in March 1991. A movement was started soon after to erect a fence around the lake, but the community was split over this need, and a consultant concluded a fence was not necessary. The lake remained free of incidents until the 8 October 2013 when a body of a 32 year old was found dead in the lake.
