Lake Pat Cleburne (Brazos River Basin)
Lake Pat Cleburne is located about four miles southwest of the city of Cleburne in Johnson County, on Nolan River, a tributary to the Brazos River. The lake, originally named the Cleburne Reservoir, is owned and operated by the city of Cleburne for flood control, municipal, industrial and agricultural water supply and recreational purposes. The reservoir was authorized by Permit No. 2027 on October 1, 1962 from Texas Water Commission. Construction of the dam began August 9, 1963 and was completed during the summer of 1964. Deliberate impoundment began August 4, 1964. The dam is an earthfill embankment of 5,050 feet long, 76 feet high and 25 feet wide at the top. The top of the dam is at elevation of 753 feet above mean sea level. Maximum design flood stage may reach to 752.3 feet above mean sea level. The uncontrolled emergence spillway is located to the right end of the dam and excavated over the natural ground with a crest of 500 feet in width and at elevation of 744 feet above mean sea level. The service spillway is located on the left end of the dam and is a concrete ogee weir with a crest of 150 feet wide at elevation of 733.5 feet above mean sea level. The lake has a conservation capacity of 26,008 acre-feet and encompasses a surface area of 1,568 acres at the conservation pool elevation of 733.5 feet above mean sea level. The drainage area above the dam is 100 square miles. Like the nearby city, the lake is later renamed in memory of Confederate general Patrick Cleburne.
