Lehr Dam, located in McIntosh County, North Dakota, is a local government-owned earth dam constructed by the Civilian Conservation Corps in 1934 for recreational purposes. Standing at a height of 15 feet and spanning 150 feet in length, this dam holds a maximum storage capacity of 147 acre-feet with a normal storage level of 110 acre-feet. Despite its low hazard potential, the dam has undergone structural modifications in 1943 to enhance its safety and performance.

Managed by the North Dakota State Water Commission, Lehr Dam is regulated, permitted, inspected, and enforced by state authorities to ensure its compliance with safety standards. Although the dam is classified as "Not Rated" in terms of condition assessment, it poses a moderate risk level of 3 on a scale. With no outlet gates and an uncontrolled spillway type, the dam presents minimal risks to surrounding areas. While the dam lacks certain emergency preparedness measures like an Emergency Action Plan (EAP) and inundation maps, its risk management measures are under review to address potential safety concerns.

Overall, Lehr Dam serves as a vital recreational resource in the area, offering opportunities for water-based activities and leisure. As climate and water resource enthusiasts, it is essential to monitor the dam's condition and risk level to ensure the safety of the surrounding community and environment. With ongoing assessments and management measures in place, Lehr Dam continues to play a significant role in water management and recreation in McIntosh County.
