Summary
Built in 1960, this earth dam stands at a hydraulic height of 18.5 feet and a structural height of 19.9 feet. With a storage capacity of 63 acre-feet and a surface area of 7.1 acres, Holt serves as a crucial water resource in the region.
Despite its low hazard potential and satisfactory condition assessment, Holt is subject to regular inspections by the state regulatory agency to ensure its safety and integrity. The dam's spillway type is uncontrolled, and it has no outlet gates or associated structures. With a drainage area of 0.05 square miles and a normal storage capacity of 53 acre-feet, Holt plays a significant role in managing water flow in the tributary of Jacobs Creek.
Managed within the Memphis District of the US Army Corps of Engineers, Holt provides moderate risk management measures and follows a three-year inspection frequency. Overall, Holt serves as a key infrastructure in the region's water resource management efforts, contributing to the conservation and regulation of water levels in the surrounding 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.
