Lehr Dam, located in Lucas, Iowa, is a privately-owned structure designed by USDA NRCS for grade stabilization purposes. Completed in 2006, this earth dam stands at a height of 33 feet and spans 399 feet in length. With a normal storage capacity of 25 acre-feet and a maximum storage of 39 acre-feet, the dam serves various purposes including fish and wildlife pond, recreation, and water supply.

Situated on a tributary to Brush Creek, Lehr Dam plays a crucial role in maintaining the ecological balance of the area while providing recreational opportunities for the community. With a low hazard potential and a condition assessment of "Not Rated," the dam is regulated, inspected, and enforced by the Iowa Department of Natural Resources. While it currently lacks certain emergency preparedness measures like an Emergency Action Plan (EAP) and inundation maps, Lehr Dam continues to serve as a vital infrastructure for water resource management in the region.

Managed by a private owner, Lehr Dam is a significant piece of infrastructure contributing to water conservation efforts in Iowa. With its stone core and soil foundation, the dam exemplifies sustainable engineering practices for grade stabilization. As water resource and climate enthusiasts, it is important to recognize and appreciate the role that structures like Lehr Dam play in enhancing the resilience of ecosystems and communities in the face of changing climatic conditions.
