Summary
The dam stands at a structural height of 34.2 feet and has a hydraulic height of 5.7 feet, impounding a maximum storage capacity of 236 acre-feet. With a normal storage capacity of 35 acre-feet and covering a surface area of 5 acres, Hico Creek serves as a vital resource for water conservation in the region.
Managed by the Tennessee Safe Dams Program, the dam has been assessed to have a low hazard potential and is currently in satisfactory condition as of the last inspection in June 2018. The risk assessment for Hico Creek indicates a moderate risk level, with risk management measures yet to be specified. Despite its relatively small size and low hazard potential, Hico Creek plays a crucial role in water resource management and climate resilience efforts in the area, highlighting the importance of maintaining and monitoring such infrastructure for the safety and well-being of the surrounding community.
As a key component of the water infrastructure in Carroll, Tennessee, Hico Creek dam is subject to state jurisdiction, permitting, inspection, and enforcement. With a drainage area of 0.51 square miles and associated with the TriBclear Creek, the dam serves as a critical structure for flood control and water storage. The dam's satisfactory condition and state oversight ensure its continued functionality and contribution to water resource management, making it a significant asset for both water resource and climate enthusiasts interested in sustainable infrastructure development.

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.
