Summary
Standing at 12 feet high with a hydraulic height of 10 feet, this dam provides a storage capacity of 136.8 acre-feet and covers a surface area of 11.4 acres. The dam, constructed with buttress and stone core types on a soil foundation, has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment.
Managed by the Louisiana Department of Transportation and Development, Turnley Dam No 2 is regulated, permitted, and inspected by the state agency to ensure safety and compliance. While the dam does not have an established completion year, its last inspection in February 2012 indicated a moderate risk level (3). Despite lacking certain emergency preparedness measures such as an Emergency Action Plan (EAP) and inundation maps, the dam's risk management measures are not specified, leaving room for improvement in emergency response and mitigation strategies. Overall, Turnley Dam No 2 serves as a vital recreational resource in the area, requiring continued monitoring and maintenance to uphold its safety standards for water resource and climate enthusiasts.

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.
