Summary
The dam stands at a height of 15 feet and has a structural height of 12 feet, with a length of 600 feet, creating a surface area of 59.6 acres and a normal storage capacity of 894 acre-feet. The dam is regulated and inspected by the Louisiana Department of Transportation and Development, ensuring its safety and compliance with state regulations.
The dam is situated on the Ten Mile Branch river or stream, within the St. Tammany County of Louisiana, and is under the jurisdiction of the Vicksburg District of the US Army Corps of Engineers. Despite being classified as having a low hazard potential, the dam's condition assessment in 2016 was deemed fair, with a moderate risk rating of 3. Emergency action plans and risk management measures for the dam are currently undetermined, highlighting the importance of continued monitoring and maintenance to ensure the safety of the surrounding community.
With its picturesque location and importance for recreational activities, Grande Hills Lake Dam serves as a vital infrastructure for the area. As climate change continues to impact water resources and extreme weather events become more frequent, the maintenance and upkeep of dams like Grande Hills Lake Dam are crucial in ensuring the protection of both the environment and the community. By staying vigilant and proactive in risk assessment and management, stakeholders can work towards safeguarding this essential water resource 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.
