Summary
Standing at a height of 17.6 feet, the dam has a storage capacity of 232.1 acre-feet and serves the primary purpose of flood risk reduction. Despite its low hazard potential, the dam's condition assessment is rated as poor, indicating potential maintenance issues that need to be addressed.
Managed by the Nebraska Department of Natural Resources, Minnick Dam is subject to state regulation, permitting, inspection, and enforcement. The dam's location in Franklin County, Nebraska, makes it a crucial asset for flood control in the area, with a drainage area of 4.52 square miles. However, the dam's poor condition raises concerns about its long-term effectiveness in mitigating flood risks and highlights the need for regular maintenance and repairs to ensure its continued functionality and safety for the surrounding community.
As a key infrastructure for flood control in the region, Minnick Dam plays a vital role in protecting the local area from potential flooding events. With its proximity to the Omaha District of the US Army Corps of Engineers, the dam's maintenance and safety are essential for safeguarding the community and surrounding lands. Taking into account its history, design, and current condition, continued monitoring and investment in Minnick Dam are crucial to maintaining its effectiveness in mitigating flood risks and ensuring the safety of those living in the area.

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.
