Summary
Standing at a structural height of 26 feet and a dam length of 655 feet, this dam plays a crucial role in managing water resources in the area. With a low hazard potential and a satisfactory condition assessment, it is regulated by the Nebraska Department of Natural Resources and undergoes regular inspections to ensure its safety and efficacy.
The dam has a storage capacity of 63 acre-feet and a maximum discharge of 335 cubic feet per second, serving a drainage area of 0.3 square miles. Even though it primarily serves flood risk reduction, it also contributes to other purposes in water resource management. The surrounding area benefits from its presence as it helps to mitigate the risk of flooding and provides essential water storage during periods of high precipitation. Managed by local government authorities, Spring Creek 8-1 stands as a testament to effective water resource infrastructure in Nebraska.
With its stone core and soil foundation, Spring Creek 8-1 is a well-engineered structure that has withstood the test of time, showcasing the expertise of the Natural Resources Conservation Service in dam construction. Its location in the vicinity of the TR-Spring Creek river and stream highlights its importance in the local hydrological system. As a key component in the water management infrastructure of the region, Spring Creek 8-1 serves as a valuable asset for climate and water resource enthusiasts interested in sustainable solutions for flood control and water storage.

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.
