Summary
Situated on Trout Creek, this Earth-type dam stands at a height of 15 feet and has a maximum storage capacity of 150 acre-feet. With a surface area of 14 acres and a drainage area of 0.55 square miles, the dam serves as a popular spot for outdoor activities such as fishing, boating, and picnicking.
Although the dam has a low hazard potential, its condition assessment is marked as poor, as of the last inspection in September 2018. Despite this, the dam still plays a crucial role in providing recreational opportunities for the local community. With an uncontrolled spillway and a moderate risk assessment rating of 3, there is a need for ongoing risk management measures and regular inspections to ensure the safety and integrity of the structure for both visitors and the surrounding environment.
Overall, Gerald Johnson Dam's historical significance, combined with its recreational value, makes it a vital part of the water resource infrastructure in Beauregard, Louisiana. As climate change continues to impact water resources, it is essential to prioritize the maintenance and upkeep of such structures to ensure their long-term sustainability and safety for future generations of water and climate enthusiasts.

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.
