Summary

Owned by the local government, this earth dam stands at a height of 36 feet and has a hydraulic height of 35 feet, providing protection to the surrounding area. Completed in 1963, this structure has a normal storage capacity of 190 acre-feet and a maximum discharge of 12,053 cubic feet per second.

Managed by the Nebraska Department of Natural Resources, Upper Salt Creek 10-A has undergone modifications in 2009 to enhance its hydraulic and structural components. Despite being classified as having a high hazard potential, the dam is currently in satisfactory condition based on the latest assessment conducted in October 2020. With a drainage area of 3.3 square miles and a storage capacity of 1,689 acre-feet, this dam plays a crucial role in mitigating flooding risks and ensuring the safety of the local community.

The designer of Upper Salt Creek 10-A is USDA NRCS, with oversight from the Natural Resources Conservation Service. With a location in Rural Hickman, this structure on TR-Salt Creek is subject to state regulation, permitting, inspection, and enforcement. As a key component in the flood risk reduction strategy for the area, Upper Salt Creek 10-A stands as a testament to the importance of proper water resource management and climate resilience efforts in safeguarding communities against potential natural disasters.

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.
