Summary

This earth dam, completed in 2005, stands at 27 feet high and has a length of 810 feet, providing essential protection for the surrounding area. With a normal storage capacity of 21.9 acre-feet and a maximum discharge capability of 2779 cubic feet per second, this dam plays a crucial role in managing the water levels in the Stevens Creek watershed.

Managed by the Nebraska Department of Natural Resources, Stevens Creek A5-1 is part of the state's regulatory framework, ensuring that inspections, permitting, and enforcement measures are in place to maintain its structural integrity and safety standards. Despite its low hazard potential and satisfactory condition assessment, regular inspections are conducted every 5 years to guarantee its effectiveness in flood risk reduction. The dam's proximity to the TR-Stevens Creek river/stream highlights its strategic importance in mitigating potential flood events and safeguarding the local community.

With its stone core and soil foundation, Stevens Creek A5-1 serves as a critical infrastructure asset in the region, offering not only flood protection but also contributing to water resource management. Its storage capacity of 186 acre-feet and surface area of 9 acres demonstrate its significant role in regulating water flow and reducing flood risks. As climate change continues to impact the frequency and intensity of extreme weather events, structures like Stevens Creek A5-1 play a crucial role in enhancing resilience and adaptation strategies for water resource management in Nebraska's landscape.

Dam Data Reference

Condition Assessment

Satisfactory
No 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

High
Dams 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.
