Summary

Completed in 1998, this earth dam stands at 25 feet high with a structural height of 28 feet and a length of 723 feet. It has a storage capacity of 108 acre-feet and serves the primary purpose of flood risk reduction in the area.

Managed by the Nebraska Department of Natural Resources, the Roland Moellenberndt Dam is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and compliance with regulations. The dam has a low hazard potential and is assessed to be in fair condition as of the last inspection in April 2020. While there are no spillways or locks associated with the structure, its proximity to the TR-Dry Branch river and its drainage area of 0.9 square miles make it a crucial component in managing water resources in Jefferson County.

Overall, the Roland Moellenberndt Dam plays a vital role in mitigating flood risks and protecting the surrounding area from potential water-related disasters. With its strategic location and design, this earth dam stands as a testament to effective water resource management efforts in Nebraska, showcasing the importance of infrastructure in addressing climate-related challenges.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
