Lenhart, a privately owned dam located in Woods County, Oklahoma, is regulated by the Oklahoma Water Resources Board. Completed in 1960, this earth dam stands at a height of 30 feet and has a storage capacity of 270 acre-feet. It serves as a crucial structure on the TR Yellowstone Creek, with a controlled spillway and one outlet valve for water discharge.

Despite being classified as having low hazard potential, Lenhart is considered to have a very high risk assessment, indicating potential risks that may require careful monitoring and management. The dam has not been rated for its condition assessment, and the last inspection was conducted in 2010. However, with a history of state regulation, inspection, and enforcement, Lenhart remains a key infrastructure for water resource and climate management in the region.

Overall, Lenhart's significance lies not only in its storage and flood control capabilities but also in its role in water resource management in Oklahoma. As a privately owned structure with state jurisdiction and regulation, its operation and maintenance are critical for ensuring the safety and sustainability of the surrounding area's water supply and ecosystem.
