Summary
Built in 1965 by the USDA NRCS, this dam stands at a height of 48 feet with a hydraulic height of 44 feet. It has a storage capacity of 580 acre-feet and a surface area of 29 acres, serving as a critical infrastructure to manage water resources in the region.
The dam is situated on the TR-Beaver Creek and is under the jurisdiction of the OWRB. Despite being classified as low hazard potential, the risk assessment for SCS-Beaver Creek Site-11 indicates a very high risk level, warranting close monitoring and potential risk management measures. The dam is equipped with a controlled spillway and a single valve outlet gate, with inspection frequency set at every five years, although the last recorded inspection dates back to 1980, raising concerns over the current condition assessment and emergency preparedness of the structure.
As a significant piece of water infrastructure in the area, SCS-Beaver Creek Site-11 plays a crucial role in flood risk reduction and water resource management. However, with the outdated inspection records and elevated risk level, there is a pressing need for updated assessments, emergency action plans, and risk management strategies to ensure the safety and effectiveness of this essential dam in the face of changing climate patterns and growing water resource challenges.

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.
