 In 1969, the Fairfax County Board of Supervisors and the Northern Virginia Soil District signed contracts which allowed the construction of the dam impounding the tributary of the Pohick creek in Burke.The $138,500 cost of the dam, intended as the first of eight to control soil erosion and flooding in the Pohick watershed, was split between the U.S. Department of Agriculture and the Yeonas Development Corporation, the latter of which intended to build a 1000-unit development on the surrounding 400 acres.The ultimate cost of the dam creating the 19-acre lake was $93,000 to the U.S. Government and $104,000 to Yeonas.
