Located in Jefferson, Nebraska, the Lottman-Carpenter Dam stands as a testament to innovative water resource management practices. Built in 1969 by the USDA NRCS, this earth dam primarily serves the purpose of irrigation, providing vital water supply to the surrounding agricultural lands. With a height of 25 feet and a length of 285 feet, the dam holds a maximum storage capacity of 42 acre-feet, supporting a drainage area of 0.05 square miles.

Managed by a private entity, the dam is regulated by the Nebraska Department of Natural Resources, ensuring state inspection, permitting, and enforcement. Despite its low hazard potential and a condition assessment that is currently not rated, the dam remains a critical infrastructure for water management in the region. The Lottman-Carpenter Dam is a key component of the local water supply system, supporting the farming community and contributing to the sustainable use of water resources in the area.

With its strategic location on TR-SPRING CREEK and under the oversight of the Omaha District of the US Army Corps of Engineers, the Lottman-Carpenter Dam plays a crucial role in controlling water flow, enhancing irrigation efficiency, and mitigating potential flood risks. As a symbol of collaboration between private ownership, government regulation, and environmental conservation, the dam represents a harmonious blend of human ingenuity and natural resource stewardship in the face of changing climate conditions.
