Summary

is a privately owned dam located in Fentress, Tennessee, regulated by the Tennessee Safe Dams Program. Built in 2001 by MARK V Engineering, this earth dam on Crooked Creek stands at a hydraulic height of 25.4 feet and a structural height of 29.4 feet, with a length of 350 feet. The dam has a normal storage capacity of 45 acre-feet and serves a variety of purposes beyond flood control, making it a vital water resource in the region.

Despite its low hazard potential and satisfactory condition assessment, Allardt Land Co. undergoes regular inspections every three years to ensure its safety and reliability. The dam features an uncontrolled spillway and has not been modified since its completion. With a risk assessment rating of moderate (3), the dam is subject to ongoing risk management measures to protect against potential hazards. Overall, Allardt Land Co. plays a crucial role in managing water resources in the area and highlights the importance of sustainable infrastructure for climate resilience.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
