Summary
Completed in 2010, this earth dam structure stands at 15 feet high and has a storage capacity of 210 acre-feet. The pond covers a surface area of 28 acres and is fed by TR - Garrison Creek, making it an important habitat for various species of aquatic life.
Despite its low hazard potential and fair condition assessment, Holmes Pond is subject to state regulation and inspection by the Louisiana Department of Transportation and Development. The spillway width of 173 feet ensures that the pond can handle a maximum discharge of 1825 cubic feet per second. The structure was last inspected in October 2016, with a frequency of inspections every 5 years to ensure its safety and functionality. With a risk assessment rating of moderate (3), the pond is considered to have a manageable level of risk.
Overall, Holmes Pond provides a valuable resource for the local community in Longstreet, Louisiana, supporting biodiversity and recreational activities while also serving as a water source. Its well-maintained dam and regulated status demonstrate a commitment to environmental stewardship and public safety, making it a key location for water resource and climate enthusiasts to appreciate and monitor.

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.
