Summary
Completed in 1964, this dam stands at a height of 21 feet and has a length of 750 feet, providing a storage capacity of 96 acre-feet. The dam is situated on the TR-Finn Creek and falls under the jurisdiction of the OWRB, with state permitting, inspection, and enforcement in place to ensure its safety and functionality.
With a hazard potential rated as high and a risk assessment indicating a very high level of risk, SCS-Finn Creek Site-003a is closely monitored through regular inspections, with the last one conducted in November 2011. The dam features a controlled spillway and a single valve outlet gate, emphasizing its importance in managing water flow and reducing flood risks in the region. As a critical infrastructure for water resource management in the area, this dam serves as a key asset in protecting local communities from potential flooding events and highlights the collaborative efforts between state agencies and the USDA NRCS in ensuring the safety and resilience of the region's water resources.

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.
