Summary
Completed in 2005, this dam stands at a height of 25 feet with a structural height of 32 feet and a length of 905 feet. With a storage capacity of 256 acre-feet and a drainage area of 0.5 square miles, Stevens Creek A2-1 plays a crucial role in managing water levels and protecting the surrounding area from potential flooding.
Owned by the local government and regulated by the Nebraska Department of Natural Resources, Stevens Creek A2-1 has a high hazard potential but was assessed to be in satisfactory condition as of October 2020. The dam is equipped with emergency action plans and undergoes regular inspections to ensure its integrity and functionality. With a maximum discharge capacity of 3087 cubic feet per second, this structure is essential for mitigating flood risks in the region and maintaining water resource sustainability in the face of changing climate patterns.
As a key component of the flood risk reduction infrastructure in rural Lincoln, Stevens Creek A2-1 not only provides critical protection for the local community but also serves as a symbol of proactive water resource management. Its strategic location and efficient design make it a valuable asset for safeguarding against potential disasters and ensuring the long-term resilience of the area. With ongoing monitoring and maintenance, this earth dam continues to play a crucial role in water resource management and climate adaptation efforts in Nebraska.

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.
