Summary
This earth dam stands at 22 feet high and has a hydraulic height of 19 feet, serving to control the flow of water and protect the surrounding area from potential flooding events. With a storage capacity of 240 acre-feet, the dam plays a crucial role in managing water levels and mitigating flood risks in the region.
Despite being classified as having a low hazard potential, the dam at Site-27 is crucial for ensuring the safety and security of the local community. The dam features a controlled spillway and a single valve outlet gate, with a maximum discharge capacity of 1322 cubic feet per second. While the dam has not been inspected since 1988, it is important to recognize its role in flood risk reduction and the need for regular maintenance and monitoring to ensure its continued effectiveness in safeguarding the area from potential water-related disasters.
As water resource and climate enthusiasts, it is important to stay informed about the state of infrastructure like the SCS-Tri-County Turkey Creek Site-27 dam. Understanding the design, purpose, and condition of such structures is essential for promoting sustainable water management practices and ensuring the resilience of communities in the face of changing climate patterns. Monitoring and supporting the upkeep of dams like Site-27 can help protect both the environment and the livelihoods of those who rely on the reliable management of water resources in the region.

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.
