The dam, designed by Mr. McKinney, is primarily used for recreational purposes, offering a serene escape for water resource and climate enthusiasts. With a dam height of 23 feet and a length of 833 feet, it harnesses the waters of Alazan Bayou, providing a surface area of 64 acres and a normal storage capacity of 470 acre-feet.
Over the years, Lake Alazan Dam has undergone several modifications to enhance its structural integrity and hydraulic efficiency. Notable upgrades in 1937, 1985, and 2008 have contributed to its current fair condition assessment. The dam features an uncontrolled spillway and two uncontrolled gates, showcasing a blend of traditional earth and stone core construction. Additionally, the dam boasts a maximum discharge capacity of 8,812 cubic feet per second, ensuring effective flood control measures in the region.
While Lake Alazan Dam presents a moderate risk level, its regulatory oversight by the Texas Commission on Environmental Quality (TCEQ) ensures that proper inspection, enforcement, and permitting protocols are in place. The dam's strategic location within the Fort Worth District further emphasizes its importance in water resource management. As a symbol of harmonious coexistence between nature and human intervention, Lake Alazan Dam continues to invite exploration and admiration for its timeless engineering marvel.
