Gantz Dam, located in Natrona, Wyoming, along the South Fork Okie Draw river, serves as a vital structure for debris control, with a primary purpose of preventing the buildup of hazardous materials. Owned and managed by the Bureau of Land Management, this gravity dam stands at a structural height of 34 feet and a hydraulic height of 30 feet, completed in 1964. With a storage capacity of 42 acre-feet and a surface area of 3.8 acres, the dam plays a crucial role in managing water resources in the region.

Despite its low hazard potential, Gantz Dam undergoes regular inspections by the Bureau of Land Management every five years to ensure its structural integrity and functionality. The dam, built using buttress and stone core types on an unlisted foundation, has not been rated for its condition assessment yet. While it does not have a spillway or outlet gates, the dam's maximum discharge capacity is recorded at 421 cubic feet per second. Additionally, the dam does not fall under the jurisdiction of any state regulatory agency, demonstrating the federal oversight and responsibility in its operations, design, and construction.

With Gantz Dam's historical significance and role in managing water resources, it stands as a testament to the collaborative efforts between federal agencies and local communities in ensuring the safety and sustainability of water infrastructure. As climate change continues to impact water availability and quality, structures like Gantz Dam play a crucial role in mitigating risks and protecting ecosystems downstream. By maintaining a proactive approach to dam management and regular inspections, Gantz Dam exemplifies a commitment to safeguarding water resources for future generations while adapting to evolving environmental challenges.
