Lake Halbert (Trinity River Basin)
Lake Halbert is located about four miles southeast of Corsicana in central Navarro County, on Little Elm Creek, a tributary of the Post Oak Creek, a tributary of the Richland Creek which is a tributary of the Trinity River. The lake is owned and operated by the city of Corsicana for municipal, industrial, and recreational purposes. Construction of the dam was started in 1920 and completed in 1921. Water Right Permit No. 803 (Application No. 841) was issued to City of Corsicana on July 1, 1925 and authorized the already constructed dam and impoundment.
The dam is an earthfill structure, 2,780 feet long, with the top at an elevation of 375 feet above mean sea level. A concrete spillway located on the left end of the dam has a crest length of 175 feet at elevation of 368 feet above mean sea level. When built prior to 1924 the Dam had a 2 to 1 slope. In 1994 due to damage from weather the Dam was reworked to the present 4 to 1 slope. According to the 1999 TWDB volumetric survey, the reservoir had a storage capacity of 6,033 acre-feet, with a surface area of 603 acres, at its conservation pool elevation, 368 feet above mean sea level. The drainage area above the dam is twelve square miles.
