Summary
Built in 1960 by the USDA NRCS, this earth-type dam stands at a height of 18 feet and spans a length of 550 feet, with a storage capacity of 165 acre-feet. The dam is situated along the Tallahala Creek, under the jurisdiction and regulation of the Mississippi Department of Environmental Quality.
Despite being categorized with a low hazard potential and fair condition assessment, Holmes Lake Dam poses a moderate risk, as indicated by a risk assessment rating of 3. The dam features an uncontrolled spillway and outlet gates, with no associated locks for water control. While the last inspection in June 2017 revealed a satisfactory condition, there is limited information available on emergency preparedness measures such as an Emergency Action Plan (EAP) or updated contact information.
Water resource and climate enthusiasts interested in the management and maintenance of dams like Holmes Lake Dam may find its design and operational details intriguing. With the potential for recreational activities and its location along Tallahala Creek, the dam serves as a key infrastructure for water storage and management in the region, highlighting the importance of regular inspections and risk assessments to ensure public safety and environmental protection.

Dam Data Reference
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.
