Summary
Completed in 1987, this earth dam stands at a structural height of 44.4 feet and a hydraulic height of 21.2 feet, with a storage capacity of 1229 acre-feet. The dam plays a crucial role in protecting the surrounding area from potential flooding, as it is regulated and inspected by the Tennessee Safe Dams Program.
With a high hazard potential and a satisfactory condition assessment, Hurricane Creek #8 poses a moderate risk (3) according to the available data. Despite the lack of outlet gates, the dam's uncontrolled spillway type ensures effective water discharge during peak flow events. The dam's importance in flood control is underscored by its location within the Nashville District and the involvement of the Natural Resources Conservation Service in its design.
As a water resource and climate enthusiast, the intricacies of Hurricane Creek #8's design, purpose, and regulatory oversight make it a fascinating subject of study. Its role in mitigating flood risks in the region, coupled with the ongoing inspections and maintenance efforts, highlight the collaborative efforts of local government agencies and the USDA NRCS in safeguarding communities against potential water-related disasters. The dam's historical significance, combined with its functional design and operational efficiency, showcases the intersection of engineering, environmental protection, and public safety in water resource management.

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.
