Summary
Constructed in 1963 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along the TRIBWRIGHT BRANCH river or stream. With a hydraulic height of 18 feet and a structural height of 21 feet, this dam has a normal storage capacity of 49 acre-feet and a maximum storage capacity of 354 acre-feet, covering a surface area of 16.5 acres.
Maintained and regulated by the Tennessee Safe Dams Program, Cypress Creek #9 has a high hazard potential and a satisfactory condition assessment as of its last inspection in February 2021. Despite its moderate risk level, the dam has not been modified in recent years and does not currently have outlet gates for controlled release of water. With a history of successful flood risk reduction and a dedicated regulatory agency, Cypress Creek #9 remains a crucial component of water resource management in the region.
For water resource and climate enthusiasts, Cypress Creek #9 presents an intriguing case study of private dam ownership and regulation in Tennessee. With its earth core and stone foundation, this dam showcases the importance of proactive maintenance and regular inspections to ensure community safety and effective flood risk reduction. As climate change continues to impact water resources, understanding the management and maintenance of dams like Cypress Creek #9 is essential for sustainable water resource management in the face of evolving environmental challenges.

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.
