Joe Pool Lake, also known as Joe Poole Lake, Joe Pool Reservoir, and Lakeview, is on Mountain Creek in southwestern Dallas and southeastern Tarrant counties (at 32°38' N, 97°00' W). The northeastern corner of the lake is in the city limits of Dallas, and most of the remainder is in the city limits of Grand Prairie. The lake was named after Joe Pool, a congressman from Oak Cliff, and is operated by the Trinity River Authority for conservation, flood control, recreation, and municipal water supply. The dam, a rolled earthfill structure with a spillway elevation of 536 feet, was completed in December 1985, and impoundment of water began in January 1986. The lake was filled by June 1989. It covers 7,470 surface acres, has a conservation storage capacity of 176,900 acre-feet, and drains an area of 232 square miles. Recreation facilities at Joe Pool Lake include a number of parks, paved boat ramps and parking lots, public swimming areas, and a public marina. Loyd Park and Lynn Creek Park are on the lake's northern edge, Estes Park is between the two arms of the lake, and Pleasant Valley Park and Cedar Hill State Park are on its southern side. The lake is stocked with bass and catfish.
