Summary
Completed in 1979, this dam stands at a height of 36 feet and has a capacity of 952 acre-feet for storage. With a controlled spillway and one outlet valve, this dam has a low hazard potential and is currently in a not rated condition assessment.
Despite its low hazard potential, the SCS-Upper Black Bear Creek Site-09 poses a very high risk due to its location and structural characteristics. The dam has not been inspected since 1999, with an inspection frequency of 5 years. The surrounding area has a risk assessment rating of 1, indicating a high level of vulnerability in case of a failure. It is important for water resource and climate enthusiasts to monitor the condition of this dam and advocate for regular inspections and maintenance to mitigate any potential risks.
As part of the flood risk reduction infrastructure in Noble, Oklahoma, the SCS-Upper Black Bear Creek Site-09 plays a crucial role in protecting the surrounding area from potential flooding. With its state jurisdiction and regulated status, it is essential for the OWRB and other relevant agencies to ensure that this dam is properly maintained and inspected to prevent any disasters. Water resource and climate enthusiasts can contribute to the safety of this dam by advocating for regular inspections, emergency preparedness plans, and risk management measures to safeguard the community and environment from potential harm.

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.
