Summary
Standing at 25 feet tall with a structural height of 25 feet, this dam has a storage capacity of 501 acre-feet and a normal storage of 90 acre-feet, covering a surface area of 31 acres. The dam boasts a controlled spillway type with a width of 1 foot, and is equipped with a single valve outlet gate for water release.
Despite being classified as low hazard potential, this dam poses a very high risk due to its location and age, with a risk assessment rating of 1. The condition of the dam has not been rated since its last inspection in 1980, with an inspection frequency of 5 years. While the dam meets state permitting, inspection, and enforcement requirements, there is limited information available on emergency action planning, risk management measures, and inundation maps. With the potential for high discharge rates of up to 3100 cfs, the safety and maintenance of SCS-Mill Creek Site-14 remain crucial for ensuring the protection of surrounding areas 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.
