BARKER RESERVOIR. Barker Reservoir is southwest of the intersection of U.S. Highway 90 and State Highway 6, about one mile south of Addicks in western Harris County (at 29°46' N, 95°39' W). The reservoir is formed on Buffalo Bayou by a rolled-earth dam 72,900 feet long and 112.5 feet high. The spillway elevation is 73.2 feet, and the drainage area covers 128 square miles. The storage capacity of the reservoir, 199,000 acre-feet, expands to 209,000 acre-feet at flood stage. The purpose of the reservoir is to provide flood control on the Buffalo Bayou watershed in the San Jacinto River basin for the city of Houston. Water is stored in the reservoir until it can be released to flow downstream without endangering property. The United States Army Corps of Engineers completed the Barker dam in February 1946, but the reservoir had already been used in 1945 for spring flood control. The total storage capacity of the Barker Reservoir and the adjacent Addicks Reservoir is 411,500 acre-feet.
