Summary

Managed by the Louisiana Department of Transportation and Development, this earth dam stands at 21 feet high with a hydraulic height of 16 feet. The dam serves multiple purposes, including recreational activities, with a storage capacity of 200 acre-feet and a surface area of 10.5 acres.

Despite its fair condition assessment and high hazard potential, Breckenridge Lake Dam has a moderate risk rating of 3. The uncontrolled spillway, measuring 30 feet in width, ensures a maximum discharge of 1115 cubic feet per second. The dam's inspection frequency is once a year, with the last assessment conducted in July 2020. While there are no associated structures or outlet gates, the dam poses a potential risk that is being actively managed to ensure the safety of the surrounding area.

Water resource and climate enthusiasts will find Breckenridge Lake Dam an intriguing structure due to its unique design and significant impact on the local environment. With its historical significance and ongoing regulatory oversight, this dam serves as a vital component of the water management infrastructure in Caddo, Louisiana.

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.
