Summary
With a height of 25 feet and a length of 725 feet, this dam holds a NID storage capacity of 244 acre-feet and serves a drainage area of 0.7 square miles. Despite its fair condition assessment as of November 2020, the dam poses a significant hazard potential and undergoes inspections every 3 years to ensure its structural integrity.
Managed by the local government with state regulatory oversight from the NE DNR, Upper Salt Creek 4-A is crucial for protecting the surrounding area from potential flooding events. Situated in SES26T8R6E, the dam's location underscores its strategic importance in mitigating flood risks in the region. With a maximum discharge capacity of 2000 cubic feet per second, this structure plays a crucial role in safeguarding the community and maintaining water resource sustainability in the face of changing climate patterns.
As a key component of flood risk management infrastructure in Nebraska, Upper Salt Creek 4-A underscores the collaborative efforts between federal and state agencies in ensuring public safety and water resource protection. With a focus on enhancing resilience against flooding and maintaining operational efficiency, this dam serves as a testament to the importance of proactive maintenance and regulatory oversight in safeguarding communities and ecosystems from the impacts of extreme weather events.

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.
