Summary
This earth dam stands at a height of 22 feet with a hydraulic height of 19 feet and a length of 850 feet. It has a storage capacity of 212 acre-feet and a normal storage of 82 acre-feet, serving as a crucial structure in controlling the flow of water in the area.
Despite being categorized as having a low hazard potential, the risk assessment for SCS-Tri-County Turkey Creek Site-11 indicates a very high risk level (1). The dam features a controlled spillway type with a width of 1 foot and one valve outlet gate. The last inspection was conducted in June 1988, with an inspection frequency of 5 years. The dam's condition is currently not rated, and there is no Emergency Action Plan (EAP) prepared or updated, raising concerns about the dam's readiness for potential emergencies.
As water resource and climate enthusiasts, the SCS-Tri-County Turkey Creek Site-11 presents an intriguing case study for understanding the management and maintenance of critical infrastructure in flood-prone areas. With its historical significance dating back to the 1960s and its impact on water control along TR-Turkey Creek, this dam serves as a focal point for exploring the intersection of engineering, environmental conservation, and risk assessment in the context of water resources management. The data provides valuable insights into the design, construction, and regulatory oversight of the dam, highlighting the importance of ongoing monitoring and assessment to ensure public safety and environmental protection.

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.
