Summary

Completed in 1954, this dam stands at a height of 9 feet and has a storage capacity of 350 acre-feet, with a normal storage capacity of 300 acre-feet. The dam is regulated by the Louisiana Department of Transportation and Development, with state permitting, inspection, and enforcement in place to ensure its safety and functionality.

Despite its low hazard potential, Olin Pond has a very high risk assessment rating due to its location and the potential impact of a breach. While the dam's condition was last assessed in 2005 and is currently not rated, its emergency action plan status and risk management measures are not specified in the available data. With a controlled spillway and a maximum discharge capacity of 30 cubic feet per second, Olin Pond plays a crucial role in managing water flow and debris in the area, contributing to the overall water resource management efforts in the region.

Overall, Olin Pond serves as a significant structure in the water resource management system along the TR-Calcasieu River, providing debris control and water storage capacity. With its regulated status and risk assessment in mind, continuous monitoring and assessment of the dam's condition and emergency preparedness measures are essential to ensure the safety and resilience of this important water resource infrastructure in 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.
