Originally constructed in 1959, the dam has since undergone reconstruction led by Twin Oaks Consulting and USDA NRCS designers, ensuring its continued functionality and reliability. The dam is primarily earth-filled with a maximum height of 32.1 feet and a storage capacity of 153.1 acre-feet, providing essential water management capabilities for the surrounding area.
Managed by a private entity, Wellensiek Dam is regulated by the Nebraska Department of Natural Resources, with state permitting, inspection, and enforcement mechanisms in place to ensure its safety and compliance with regulatory standards. Situated along the TR-S FK Little Nemaha River, the dam plays a crucial role in managing water resources and mitigating potential hazards in the region. Despite its poor condition assessment as of March 2020, ongoing maintenance and risk management measures are likely in place to address any concerns and uphold the dam's operational integrity for the benefit of the local community and ecosystem.
