Eugene Mazour Dam, located in DEWEESE, Nebraska, is a privately owned structure designed by the USDA NRCS and regulated by the NE DNR. Completed in 1990, this earth dam stands at a height of 16 feet with a structural height of 23 feet, serving primarily for irrigation purposes. With a storage capacity of 52 acre-feet, the dam covers a surface area of 4 acres and drains a 0.4 square mile watershed through the TR-LIBERTY CREEK.

Despite its low hazard potential and satisfactory condition assessment, Eugene Mazour Dam is subject to regular state inspections and enforcement to ensure its operational safety. The dam's spillway type, outlet gates, and associated structures are not specified, but its last inspection in May 2018 revealed no significant concerns. The dam's emergency action plan (EAP) status, risk assessment, and inundation maps preparedness remain unspecified, suggesting potential areas for improvement in emergency preparedness.

Eugene Mazour Dam, managed by a private entity, plays a crucial role in supporting irrigation activities in the region while maintaining a low risk profile. As water resource and climate enthusiasts, the dam's design, regulatory oversight, and storage capacity offer valuable insights into the sustainable management of water resources in Nebraska. Further attention to emergency preparedness and risk assessment could enhance the dam's resilience to potential challenges in the future.
