Lemke Dam, located in Deweese, Nebraska, is a private earth dam designed by USDA NRCS and completed in 1964. With a height of 14 feet and a length of 425 feet, the dam serves primarily for fire protection, stock, and as a small fish pond. It has a storage capacity of 65.7 acre-feet, a surface area of 6.85 acres, and drains an area of 0.2 square miles.

Managed by the Nebraska Department of Natural Resources, Lemke Dam is regulated, inspected, and enforced by state authorities to ensure its safety and functionality. The dam has a low hazard potential and is currently assessed to be in fair condition as of the last inspection in April 2017. While there are no associated structures or outlet gates, the dam's primary purpose and design make it a valuable resource for water conservation and wildlife habitat in the area.

Climate and water resource enthusiasts will appreciate Lemke Dam as a vital infrastructure for maintaining water supply, supporting local ecosystems, and mitigating fire risks in the region. Its strategic location on Liberty Creek, combined with its modest size and design features, make it a sustainable solution for multiple purposes while aligning with the state's regulatory guidelines. As an essential component of Nebraska's water management system, Lemke Dam stands as a testament to the collaborative efforts between private owners, government agencies, and environmental stewards in safeguarding our natural resources for future generations.
