Summary
Completed in 1959, this dam stands at a height of 35 feet with a hydraulic height of 30 feet and a length of 750 feet. It has a normal storage capacity of 77 acre-feet and a maximum discharge of 2480 cubic feet per second. The dam features a controlled spillway and an outlet gate valve to manage water flow.
Despite its age, SCS-Nine Mile Creek Site-09 has a low hazard potential and has not been rated for its condition assessment. The last inspection of the dam was conducted in 1980 with an inspection frequency of 5 years. The risk assessment for this dam is very high, with a DSAC assigned date not available. While the dam has not had any major modifications over the years, it is crucial to ensure that proper risk management measures are in place to mitigate any potential hazards and ensure the safety of the surrounding area.
Water resource and climate enthusiasts interested in the infrastructure of SCS-Nine Mile Creek Site-09 will appreciate the detailed data provided about the dam's construction, specifications, and risk assessment. As the dam continues to serve its primary purpose of flood risk reduction, it is important to stay informed about its condition and any necessary maintenance or improvements to ensure its effectiveness and safety for the community it protects along TR-Nine Mile Creek.

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.
