Summary
With a height of 26 feet and a length of 1280 feet, this dam has a storage capacity of 519 acre-feet and a maximum discharge of 1335 cubic feet per second. Despite being rated as low hazard potential, the dam is classified as Very High risk due to its age and the lack of recent condition assessments.
Managed by the OWRB, SCS-Salt Creek Site-49 features a controlled spillway and a single valve outlet gate. The dam has not been modified in recent years and was last inspected in 1980, with an inspection frequency of 5 years. While the condition of the dam is currently not rated, its risk assessment remains very high, indicating the need for enhanced risk management measures and potential updates to emergency action plans to ensure the safety and security of the surrounding areas in case of a flood event. For water resource and climate enthusiasts, SCS-Salt Creek Site-49 offers a fascinating case study in dam management and the intersection of infrastructure, regulation, and environmental risk assessment.

Dam Data Reference
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.
