Summary
Completed in 1976, this earth dam stands at 21 feet tall with a hydraulic height of 19 feet and a length of 870 feet. It has a NID storage capacity of 261 acre-feet and a normal storage capacity of 30 acre-feet, serving as a crucial structure in controlling the flow of TR-Black Bear Creek.
Despite being rated as having a low hazard potential, the dam at SCS-Lower Black Bear Creek Site-07 is considered to have a very high risk due to its critical function in flood risk reduction. The dam features a controlled spillway with a width of 1 foot and a single valve outlet gate for water release. While it has not undergone a condition assessment, the dam has not been rated and is not currently equipped with an Emergency Action Plan, raising concerns about its readiness in case of emergencies. As water resource and climate enthusiasts, it is crucial to monitor and address any potential risks associated with this important infrastructure to ensure the safety and protection of the surrounding community and environment.

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.
