Summary
This earth dam stands at 25 feet tall and stretches 769 feet in length, with a storage capacity of 56 acre-feet. The primary purpose of the dam is flood risk reduction, serving as a crucial structure in managing water resources in the area. It is regulated by the Nebraska Department of Natural Resources and undergoes regular inspections to ensure its fair condition and low hazard potential.
Situated in the vicinity of TR-Mans Creek, Spring Creek 10-1 plays a vital role in protecting the surrounding community from potential flooding events. With a drainage area of 0.4 square miles and a maximum discharge capacity of 245 cubic feet per second, the dam helps maintain normal storage levels of 7 acre-feet. Despite its low hazard potential, the dam is subject to state regulation, permitting, inspection, and enforcement to uphold its structural integrity and operational effectiveness. The dam's fair condition assessment in the most recent inspection in 2016 highlights its continued reliability in safeguarding the local area from water-related risks.
Managed by local government authorities, Spring Creek 10-1 stands as a testament to effective water resource management and climate resilience efforts in Nebraska. Supported by the Natural Resources Conservation Service, this dam serves as a critical infrastructure for flood risk reduction and other purposes. With its strategic location, design, and operational protocols in place, Spring Creek 10-1 embodies the collaborative efforts towards sustainable water management and climate adaptation strategies in the region.

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.
