Summary
Built in 1989 for flood risk reduction along the Ramer Branch stream, this earth dam stands at a structural height of 23.5 feet with a hydraulic height of 10.1 feet. With a normal storage capacity of 91 acre-feet and a maximum storage of 987 acre-feet, this dam plays a crucial role in managing water resources in the area.
Managed by the Tennessee Safe Dams Program, Mcnairycypress Creek #4 has a low hazard potential and is in satisfactory condition as of the last inspection in February 2021. The dam does not have outlet gates or locks and features an uncontrolled spillway type. Despite its moderate risk assessment rating, the structure meets regulatory guidelines and undergoes inspections every 3 years to ensure its continued safety and functionality. Overall, this dam serves as an essential component in mitigating flood risks and protecting the surrounding community from water-related emergencies.
Located in a picturesque setting in Rome, Tennessee, Mcnairycypress Creek #4 is a testament to the collaborative efforts of the USDA NRCS and NEEL-SCHAFFER,INC in its design and construction. With its stone core and soil foundation, this dam stands as a vital infrastructure for water resource and climate enthusiasts to appreciate and study. As a key player in flood risk reduction and water management in the area, this dam exemplifies the importance of sustainable water resource practices in a changing climate landscape.

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.
