LAKE DIVERSION. Lake Diversion, an artificial lake about seven miles long, is in northwestern Archer and northeastern Baylor counties and was formed by building a flood-control dam on the Wichita River (at 33°49' N, 98°56' W) in Archer County. It is used primarily for irrigation, with a network of canals running as far as Wichita Falls. The lake, which stands at 1,053 feet above sea level, is also an excellent recreation area. The local soils are deep clayey loams and support a variety of grasses and wild upland plants.
