Summary
Tammany, Louisiana, is a private earth dam with a primary purpose of serving as a Fish and Wildlife Pond. Constructed in 1980, this dam stands at a height of 19 feet and has a storage capacity of 320 acre-feet, with a normal storage level of 270 acre-feet. The dam spans a length of 810 feet, creating a surface area of 33.7 acres and serving a drainage area of 1.08 square miles.
Managed by the Louisiana Department of Transportation and Development, Loch Carden Dam is regulated, inspected, and enforced by state authorities to ensure its safety and functionality. The dam is designed with an uncontrolled spillway, 40 feet wide, and has a significant hazard potential with a fair condition assessment as of the last inspection in June 2018. The risk assessment for the dam is classified as moderate, highlighting the need for ongoing risk management measures to mitigate any potential threats.
With its strategic location on TR-Bills Creek and its vital role in providing water resources for fish and wildlife, fire protection, and recreational activities, Loch Carden Dam is a notable structure in the region. Its presence underscores the importance of sustainable water management practices and underscores the intersection between water resources and climate resilience. As enthusiasts of water resources and climate, monitoring the condition and risk management of Loch Carden Dam is essential to ensure its continued effectiveness in serving the community and the environment.

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.
