Summary
Built in 1962 by the USDA NRCS, this dam serves as a crucial flood risk reduction structure along the Strawberry Branch river or stream. With a structural height of 27.5 feet and a hydraulic height of 17 feet, Cypress Creek #11 has a significant hazard potential but is currently assessed to be in satisfactory condition as of its last inspection in February 2020.
Covering a drainage area of 1.1 square miles, Cypress Creek #11 has a normal storage capacity of 62 acre-feet and a total storage of 494 acre-feet. Despite being uncontrolled, the spillway of this dam ensures the safety of the surrounding area in case of excessive water flow. The dam's risk assessment indicates a moderate risk level (3), prompting the need for regular inspections and potential risk management measures to mitigate any potential hazards.
Located in the city of Latham, Tennessee, Cypress Creek #11 plays a vital role in flood prevention and water resource management in the region. With its stone core and soil foundation, this dam stands as a testament to effective engineering and design by the Natural Resources Conservation Service. As climate change continues to impact water resources, structures like Cypress Creek #11 are essential for safeguarding communities against the threats of flooding and ensuring the sustainable management of water in the area.

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.
