Lake Pat Cleburne is in the Brazos River basin four miles south of Cleburne in southwestern Johnson County (at 32°18' N, 97°26' W). The lake, originally named the Cleburne Reservoir, is owned and operated by the city of Cleburne as a municipal water supply source. Construction of a dam to impound the waters of the Nolan River began August 9, 1963, and was completed during the summer of 1964. The lake has a conservation storage capacity of 25,600 acre-feet and covers a surface area of 1,545 acres. The elevation is 733½ feet above mean sea level. The drainage area above the dam is 100 square miles. Like the nearby city, the lake is named in memory of Confederate general Pat Cleburne.
