Summary
The dam, completed in 1960, stands at a height of 10 feet with a length of 183 feet, providing a storage capacity of 52 acre-feet. Situated on TR-Muddy Creek, the dam is regulated by the Nebraska Department of Natural Resources and undergoes regular inspections to ensure its structural integrity.
Despite its low hazard potential, Sergel Dam has been assessed to be in poor condition as of June 2018. The dam, primarily constructed with earth materials and buttress stone core types, faces the challenge of maintaining its functionality for the surrounding area's water resource management needs. With a drainage area of 1.1 square miles and a maximum discharge capacity of 27 cubic feet per second, the dam plays a crucial role in managing water flow in the region.
Water resource and climate enthusiasts can appreciate Sergel Dam's contribution to local water management efforts, its historical significance, and the ongoing maintenance challenges it faces. As a privately owned structure in Congressional District 03 of Nebraska, the dam serves as a reminder of the importance of sustainable water infrastructure practices in mitigating potential risks and ensuring the long-term resilience of water resources in the area.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
