The Addicks Reservoir and Addicks Dam in conjunction with the Barker Reservoir prevent downstream flooding of Buffalo Bayou in the City of Houston. Both reservoirs were authorized under the Rivers and Harbors Act of June 20, 1938, which were modified by the Flood Control Acts of August 11, 1938; September 3, 1954; and October 27, 1965.
