Summary
Built in 1960 by USDA NRCS, this structure serves the primary purpose of flood risk reduction along the TR-Little Peavine Creek. With a storage capacity of 388 acre-feet, including a normal storage of 98 acre-feet, this dam covers a surface area of 18 acres while stretching 1550 feet in length.
Despite its age, the dam at SCS-Peavine Creek Site-10 is currently rated as 'Not Rated' in terms of condition assessment. With a high hazard potential and a risk assessment level of 'Very High (1)', it is crucial for state agencies like OWRB to conduct regular inspections, enforcement, and permitting to ensure the safety and functionality of this critical infrastructure. Additionally, the presence of a controlled spillway and a valve outlet gate indicates the dam's readiness to manage potential overflow events, with a maximum discharge capacity of 1530 cubic feet per second.
For water resource and climate enthusiasts, the SCS-Peavine Creek Site-10 presents an intriguing case study in dam management and risk mitigation. From its historical construction by USDA NRCS to its current state-regulated status under OWRB, this earth dam stands as a key player in flood risk reduction efforts along the TR-Little Peavine Creek. As discussions around infrastructure resilience and climate adaptation continue to gain prominence, understanding the condition and operational capacity of structures like SCS-Peavine Creek Site-10 becomes essential for ensuring the safety and security of communities and ecosystems in the face of changing environmental conditions.

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.
