Benbrook Lake is a reservoir on the Clear Fork of the Trinity River in Tarrant County, Texas, USA. The lake is located approximately 10 miles southwest of the center of Fort Worth, where the Clear Fork and the West Fork of the Trinity River join. The lake is impounded by the Benbrook Dam. The lake and dam are owned and operated by the U.S. Army Corps of Engineers, Fort Worth District.HistorySignificant flooding on the Trinity River during May 1908, April 1922 and September 1936, was a primary cause for the development of Corps of Engineers flood control projects in North Texas.Benbrook Dam and Lake were built by the Galveston District of the Corps of Engineers. During the decade of active civil works construction following World War II, the U.S. Congress provided for the construction of Benbrook Lake, Grapevine Lake, Lavon Lake and Ray Roberts Lake as well as modifications to the existing Garza Dam for the construction of Lewisville Lake. The River & Harbors Act of 1945 authorized these projects for the purposes of both flood control and navigation. These lakes and others, along with an extensive floodway system of levees, are operated in a coordinated manner to minimize flooding along the Trinity River floodplain corridor in the Dallas/Fort Worth Metroplex.
