Summary

Completed in 2000, this dam stands at a height of 24.6 feet and has a storage capacity of 69.9 acre-feet, with a normal storage level of 19.6 acre-feet. The dam spans 425 feet in length and is primarily constructed of stone and soil materials.

Situated on TR-Elm Creek, Moerer Dam is regulated by the Nebraska Department of Natural Resources and is subject to state jurisdiction, permitting, inspection, and enforcement. Despite its low hazard potential, the dam's condition is assessed as poor, with its last inspection conducted in March 2017. With an inspection frequency of 5 years, efforts are ongoing to ensure the safety and integrity of this critical water resource structure.

Climate and water resource enthusiasts will be intrigued by Moerer Dam's role in managing water levels and reducing flood risks in Jefferson County, Nebraska. As a key component of the local watershed, this dam, with its unique design and storage capacity, plays a vital role in protecting the surrounding community and environment from potential water-related disasters. Efforts to improve the dam's condition and emergency preparedness are essential to safeguarding its long-term functionality and ensuring sustainable water management practices for the future.

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.
