Summary
This earth dam stands at 26 feet tall with a hydraulic height of 25 feet and a length of 2860 feet, serving primarily for flood risk reduction along the Turkey Creek. With a normal storage capacity of 135 acre-feet and a maximum discharge of 6150 cubic feet per second, this dam plays a crucial role in managing water resources in the area.
Despite being classified with a low hazard potential, the risk assessment for the SCS-Tri-County Turkey Creek Site-01a indicates a very high risk level. However, the condition of the dam is currently not rated, and the last inspection was conducted in 1988. The dam features a controlled spillway and a single outlet gate, with no associated locks. While emergency action plans and risk management measures are not specified in the available data, the dam's state jurisdiction and permitting status ensure ongoing monitoring and enforcement to address any potential safety concerns.
Water resource and climate enthusiasts would be intrigued by the historical and functional aspects of the SCS-Tri-County Turkey Creek Site-01a. Its role in flood risk reduction, coupled with its location in a state-regulated area, highlights the importance of effective dam management in ensuring water security and safety for surrounding communities. The detailed specifications of the dam's design, including its height, length, and storage capacity, provide valuable insights into its operational capabilities and contribution to water resource management 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.
