Summary
Constructed in 1997 by the USDA NRCS, this earth dam stands at a height of 11 feet with a structural height of 14 feet and a length of 710 feet. With a maximum storage capacity of 98 acre-feet and a normal storage of 5 acre-feet, Regan Dam plays a vital role in mitigating potential flooding events in the area.
Managed by a private entity, Regan Dam is subject to state regulations and inspections by the Nebraska Department of Natural Resources. With a hazard potential rated as low and a fair condition assessment as of May 2018, the dam continues to provide effective flood risk reduction for the surrounding community. The dam is designed with a stone core and built on a soil foundation, showcasing a commitment to durability and structural integrity in its design.
With a focus on flood risk reduction, Regan Dam stands as a testament to effective water resource management and climate resilience efforts in Nebraska. As a key feature in the region's flood control infrastructure, this dam serves as a crucial resource for protecting the local community and environment from the impacts of potential flooding events.

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.
