Mackenzie Dam, located on Tule Creek in Briscoe, Texas, is a significant earth dam completed in 1974 with a primary purpose of recreation and water supply. Managed by the Texas Commission on Environmental Quality (TCEQ), this impressive structure stands at a height of 180 feet and spans 2,700 feet in length. With a storage capacity of 69,249 acre-feet, the dam serves as a vital resource for the surrounding area.

The dam's spillway, measuring 820 feet wide, is uncontrolled, allowing for a maximum discharge of 2 cubic feet per second. Equipped with various outlet gates, including controlled slides and uncontrolled openings, Mackenzie Dam ensures efficient water management and flood control. With a fair condition assessment and moderate risk rating, regular inspections and maintenance are conducted to ensure the dam's safety and functionality for both recreational and water supply purposes.

As a key component of the Tulsa District's water management infrastructure, Mackenzie Dam plays a crucial role in supporting the local ecosystem and providing essential water resources for the region. Its design by Freese and Nichols reflects a commitment to sustainable water management practices, making it a valuable asset for water resource and climate enthusiasts alike.
