Summary
Completed in 1976, this earth dam stands at a height of 30 feet and has a hydraulic height of 27 feet, with a storage capacity of 640 acre-feet. Its primary purpose is flood risk reduction, serving to protect the surrounding area from potential inundation during periods of high discharge. With a fair condition assessment and low hazard potential, Mission Creek 7-C plays a pivotal role in safeguarding the community against the impacts of extreme weather events.
Managed by the local government, Mission Creek 7-C is situated along the TR-Mission Creek and falls under the jurisdiction of the state of Nebraska. Its location in OKETO KS makes it a crucial infrastructure for the region, with a drainage area of 2 square miles and a maximum discharge capacity of 418 cubic feet per second. Despite its age, this structure has been regularly inspected every 5 years, ensuring its continued effectiveness in mitigating flood risks and maintaining the safety of the surrounding area. With a surface area of 28 acres and a normal storage capacity of 138 acre-feet, Mission Creek 7-C stands as a testament to effective water resource management and climate resilience efforts in the region.
As part of the flood risk reduction strategy in Nebraska, Mission Creek 7-C serves as a cornerstone for disaster preparedness and emergency response. With an associated stone core and soil foundation, this earth dam has a structural height of 35 feet and a length of 1303 feet, showcasing its robust engineering design and construction. With its low hazard potential and fair condition assessment, Mission Creek 7-C stands as a reliable infrastructure asset for the community, providing critical protection against the adverse impacts of 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.
