Summary
Completed in 1959, this dam stands at a height of 42 feet with a hydraulic height of 37 feet, serving as a vital infrastructure in the management of water resources in the area. With a storage capacity of 642 acre-feet and a spillway width of 1 foot, this low hazard potential structure plays a crucial role in mitigating flood risks along the TR-Ninemile Creek.
Although last inspected in 1980, this dam is deemed to have a very high risk assessment rating, indicating the importance of regular monitoring and maintenance. Despite its current condition assessment being marked as "Not Rated," the dam's emergency action plan and risk management measures are not specified in the available data. With the potential for significant discharge of up to 4980 cubic feet per second, the SCS-Nine Mile Creek Site-10 is a key component in the overall water resource management strategy for the region, highlighting the need for continued oversight and maintenance to ensure its effectiveness in flood risk reduction.

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.
