Cedar Grove Plantation Pond, located in Labadieville, Louisiana, is a private Earth dam structure built in 1950 with a primary purpose of recreation.


Summary

The pond has a maximum storage capacity of 360 acre-feet and a normal storage capacity of 250 acre-feet, covering a surface area of 51 acres. It is regulated by the Louisiana Department of Transportation and Development, with state permitting, inspection, and enforcement in place to ensure its safety and compliance with regulations.

The dam has a height of 7 feet and a hydraulic height of 6 feet, with a controlled spillway type that is 3 feet wide. Despite its low hazard potential and current condition being not rated, the risk assessment for Cedar Grove Plantation Pond is very high (1). The last inspection took place in July 2010, with a scheduled inspection frequency of every 5 years. The surrounding area is at risk of inundation, indicating the importance of proper risk management measures and emergency preparedness.

Enthusiasts of water resources and climate will find Cedar Grove Plantation Pond an interesting site for its recreational purposes and potential risks associated with its dam structure. With its location along Verret Bayou and the New Orleans District, it serves as a valuable water resource for the community while also highlighting the importance of proper maintenance and regulatory compliance to ensure safety and environmental sustainability.

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.
