Summary
This earth-type dam, constructed in 1983 by the USDA NRCS and Dan McGill of Owem Ayres Associates, serves as a vital asset for flood risk reduction along Tacker Creek. With a hydraulic height of 17.4 feet and a structural height of 28 feet, this dam has a storage capacity of 1,287 acre-feet and covers a surface area of 49.9 acres.
Managed by the Tennessee Safe Dams Program, this dam has been assessed to have a significant hazard potential but is currently rated as satisfactory in terms of condition. Regular inspections, with the last one conducted in July 2020, help ensure its safety and effectiveness in protecting the surrounding area from flooding. While there are no outlet gates, the dam's uncontrolled spillway provides a crucial mechanism for managing excess water during heavy rainfall events. The risk assessment for this dam is moderate, indicating the importance of continued monitoring and maintenance to mitigate potential hazards.
For water resource and climate enthusiasts, Mcnairycypress Creek #10 represents a key infrastructure piece in the region's flood risk reduction strategy. With its strategic location and design features, this dam plays a crucial role in safeguarding the community against potential flooding events. As part of the broader network of dams and structures in the area, its successful operation and maintenance are essential for ensuring the resilience of the local water resource system in the face of changing climate conditions.

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.
