Summary
Tammany, Louisiana, is a private fish and wildlife pond designed by the USDA NRCS. This earth dam structure, completed in 1996, stands at a height of 16.5 feet and has a storage capacity of 94 acre-feet. With its primary purpose being fish and wildlife conservation, the pond also serves as a recreational area for locals to enjoy.
The dam's spillway type is uncontrolled with a width of 40 feet, ensuring the safe discharge of water during periods of high flow. Despite its low hazard potential, the pond is regularly inspected every five years to ensure its structural integrity. The condition assessment in 2016 deemed the dam to be in satisfactory condition, providing assurance to the community that the pond is safe and well-maintained.
With a drainage area of 0.08 square miles and a surface area of 18.5 acres, Polly Eagan Pond plays a vital role in the local ecosystem and offers a serene retreat for nature enthusiasts. Its strategic location along TR-Black Bayou and its contribution to fish and wildlife conservation make it a valuable resource for both the environment and the community.

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.
