Summary
This man-made reservoir, completed in 1973, serves primarily as a Fish and Wildlife Pond, offering recreational opportunities and fire protection benefits. With a dam height of 16 feet and a storage capacity of 90 acre-feet, Sinclair Lake covers 8 acres and drains an area of 0.2 square miles through an uncontrolled spillway.
Despite being classified as having a high hazard potential, Sinclair Lake is currently rated in fair condition as of the last inspection in March 2020. The reservoir has a moderate risk assessment level and is subject to regular inspections and enforcement measures by the state regulatory agency. With its stone core type and soil foundation, Sinclair Lake continues to provide valuable habitat for wildlife and recreational enjoyment for visitors in the West Feliciana area.
Overall, Sinclair Lake stands as a significant water resource in Louisiana, contributing to the conservation efforts of the NRCS and providing a vital recreational space for the community. As climate change impacts continue to affect water resources, the maintenance and management of reservoirs like Sinclair Lake will be crucial in ensuring the sustainability of ecosystems and the availability of water for future generations.

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.
