Natural Dam in Texas is a local government-owned earth dam designed by FREESE AND NICHOLS to primarily reduce flood risk along the Sulphur Springs Draw of Beals Creek. Completed in 1957, this 47-foot tall structure spans 1750 feet and has a storage capacity of 207,265 acre-feet. The dam also serves secondary purposes such as fire protection, stock, or small fish pond.

Located in Howard County, Big Spring, Texas, Natural Dam has a spillway width of 500 feet and a maximum discharge capacity of 101,600 cubic feet per second. The dam's condition was assessed as satisfactory as of April 2021, with a moderate risk rating. While it has undergone modifications in 1986 and 1989, the last inspection was conducted in October 2012, with a scheduled inspection frequency of every 5 years. Despite not having a hazard potential assessment available, the dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and meets state permitting, inspection, and enforcement requirements.

Water resource and climate enthusiasts interested in the engineering and environmental aspects of dams would find Natural Dam a compelling subject. With its strategic location, design features, and operational history, this flood risk reduction structure offers valuable insights into how infrastructure can manage water resources while balancing multiple purposes and regulatory obligations.
