Summary
Standing at a height of 31 feet and with a hydraulic height of 33 feet, this dam serves the primary purpose of flood risk reduction, with a normal storage capacity of 85 acre-feet and a maximum storage of 448 acre-feet. The dam spans 696 feet in length and has a surface area of 12 acres, making it a crucial structure in managing water resources in the area.
Despite its important role in flood risk reduction, Sandy Creek WS Structure # 12 poses a high hazard potential and is currently assessed to be in poor condition as of the last inspection in January 2017. The dam's condition is a cause for concern, with a moderate risk level of 3 out of 5. The dam features an uncontrolled spillway and outlet gates, reflecting the need for regular inspections and maintenance to ensure its structural integrity and continued effectiveness in managing water flow in the region. As water resource and climate enthusiasts, it is vital to monitor and address the condition of such critical infrastructure to safeguard against potential risks and ensure the sustainable management of water resources in the area.

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.
