Summary
Built in 1971 by USDA NRCS, this earth dam stands at 32 feet tall and spans 897 feet in length, with a storage capacity of 437 acre-feet. Despite its relatively low hazard potential, the dam is regularly inspected by the Nebraska Department of Natural Resources to ensure its structural integrity and satisfactory condition.
Managed by the local government, Spring Creek 7-C plays a vital role in protecting the surrounding area from potential flooding events. With a drainage area of 1.5 square miles and a maximum discharge capacity of 985 cubic feet per second, this structure serves as a key component in the flood control system for the region. Its presence is a testament to the collaborative efforts between federal and state agencies in safeguarding water resources and enhancing climate resilience in the area.
As part of the broader water management infrastructure in Nebraska, Spring Creek 7-C not only provides flood protection but also contributes to the conservation and sustainable use of water resources. With its satisfactory condition and regular inspections, this earth dam exemplifies the importance of proactive maintenance and monitoring to ensure the continued effectiveness of water management structures in the face of changing climate conditions.

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.
