Summary
Standing at a height of 19.1 meters and spanning 425 meters in length, the dam has a storage capacity of 107.6 acre-feet, with a normal storage level of 42 acre-feet. Despite its low hazard potential, the dam's condition assessment in 2017 indicated poor structural health, prompting the need for further inspection and potential maintenance to ensure its continued effectiveness in protecting the surrounding area from flooding.
Managed by the Nebraska Department of Natural Resources and regulated at the state level, Duchek Dam serves as a vital infrastructure for flood control in Saline County. While the dam's primary purpose is flood risk reduction, its design and construction also highlight the importance of sustainable water resource management in mitigating the impacts of extreme weather events and climate change. With a drainage area of 0.9 square kilometers and a surface area of 8.2 hectares, the dam plays a crucial role in safeguarding local communities and ecosystems from potential flood damage.
As water resource and climate enthusiasts, understanding the significance of Duchek Dam as a key element of Nebraska's flood control infrastructure underscores the importance of proactive monitoring and maintenance to ensure its continued functionality and resilience in the face of evolving environmental challenges. By recognizing the role of dams like Duchek in protecting vulnerable regions from flooding and promoting sustainable water management practices, we can contribute to building more resilient and adaptive communities in the face of a changing climate.

Dam Data Reference
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.
