Summary
Sediment Ponds, located in Iberia, Louisiana, serve as an essential water management system along the Bayou Teche offstream. Built in 1942, these Earth type dams stand at a height of 13 feet and have a maximum storage capacity of 125 acre-feet. Despite their low hazard potential, the poor condition assessment in 2012 poses a challenge for maintaining the structural integrity of these ponds.
The primary purpose of the Iberia Sugar Co-Op, INC. Sediment Ponds is for sediment retention and water quality management, making them vital for the agricultural activities in the region. The controlled spillway type and the drainage area of 1 square mile further highlight their significance in managing water flow and preventing potential flooding. However, with a very high risk assessment ranking and a lack of recent updates on emergency preparedness measures, there is a pressing need for improved maintenance and risk management strategies.
Given the critical role of these sediment ponds in the local water resource infrastructure, collaboration between the private owners, regulatory agencies like the LA DOTD, and the community is essential to ensure their long-term effectiveness and resilience in the face of climate change challenges. By prioritizing regular inspections, condition assessments, and emergency response planning, the Iberia Sugar Co-Op, INC. Sediment Ponds can continue to safeguard water resources and mitigate potential risks for both the environment and the surrounding communities.

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.
