Summary

Completed in 1957, this earth dam stands at a height of 27 feet and serves the primary purpose of flood risk reduction along the TR-OLIVE BR SALT CREEK. With a storage capacity of 250 acre-feet, the dam covers a surface area of 11 acres and drains a 0.7 square mile watershed.

This dam has a low hazard potential and has been assessed as satisfactory during the last inspection conducted in November 2016. The condition assessment deemed the structure in good shape, with a height of 28 feet and a hydraulic height of 24 feet. The dam's normal storage capacity is 60 acre-feet, with a maximum discharge rate of 480 cubic feet per second. While no spillway type is specified, the dam has not been modified over the years and does not feature outlet gates or associated structures.

Overall, Upper Salt Creek 14-A plays a crucial role in mitigating flood risks in the area and is maintained to a satisfactory standard by local authorities. It stands as a testament to effective water resource management and climate resilience efforts in the region, ensuring the safety and protection of surrounding communities from potential flooding events.

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.
