Summary
Designed by the USDA NRCS, this earth dam stands at a height of 33 feet and has a structural height of 36 feet, serving as a crucial defense against potential flooding in the area. Completed in 1970, the dam has a storage capacity of 1107 acre-feet and covers a surface area of 35 acres, with a drainage area of 4.5 square miles.
Located on TR-STREVER CREEK, this dam is regulated by the Nebraska Department of Natural Resources and undergoes regular inspections to ensure its satisfactory condition and low hazard potential. With a maximum discharge capacity of 1096 cubic feet per second, Spring Creek 9-B plays a vital role in protecting the surrounding area from potential flood events. Despite its importance for flood risk reduction, the dam has not been modified in recent years and continues to meet regulatory guidelines.
With its strategic location and effective design, Spring Creek 9-B stands as a testament to the collaborative efforts of local government agencies and the USDA NRCS in safeguarding communities against the threat of flooding. As water resource and climate enthusiasts, this structure serves as a prime example of proactive measures taken to mitigate flood risks and protect the environment for future generations. The ongoing maintenance and inspection of Spring Creek 9-B highlight the commitment to ensuring its continued effectiveness in managing water resources and enhancing resilience in the face of changing climate patterns.

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.
