Scs-Upper Black Bear Creek Site-69 Reservoir Report
Last Updated: December 7, 2025
SCS-Upper Black Bear Creek Site-69 is a state-regulated earth dam located in Noble, Oklahoma, designed by USDA NRCS and completed in 1966 for the primary purpose of flood risk reduction along the TR-Black Bear Creek.

Summary
With a height, hydraulic height, and structural height of 25 feet, the dam stretches over 1200 feet and has a maximum storage capacity of 165 acre-feet. Despite its low hazard potential, the risk assessment categorizes this dam as having a very high risk due to its condition assessment being "Not Rated."
Managed by the Oklahoma Water Resources Board (OWRB), this dam features a controlled spillway type with a width of 1 foot and an outlet gate in the form of a single valve. While the last inspection took place in 1999 with an inspection frequency of 5 years, the condition assessment remains "Not Rated." The associated risk management measures, emergency action plan (EAP), and inundation maps for this dam are currently not prepared or up to date, indicating potential gaps in emergency response readiness.
Located in Sumner, Oklahoma, this dam falls under the jurisdiction of the Tulsa District of the US Army Corps of Engineers. With Representative Frank D. Lucas (R) overseeing this area, the SCS-Upper Black Bear Creek Site-69 dam stands as a crucial infrastructure for flood risk reduction in the region, despite the need for updated risk assessments and emergency preparedness measures to ensure the safety of surrounding communities and 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.
