Summary
Built in 1967 by the USDA NRCS, this earth dam stands at a height of 25 feet and has a structural height of 28 feet, with a length of 327 feet. It has a storage capacity of 50 acre-feet and covers a surface area of 3.7 acres, drawing water from TR-Cypress Creek.
Despite its low hazard potential, Wiltcher Dam is currently in poor condition, as assessed in July 2019. With a moderate risk assessment rating of 3, there are concerns about its long-term safety and effectiveness. The dam is regulated by the Louisiana Department of Transportation and Development, with state inspection, permitting, and enforcement in place. With a drainage area of 0.07 square miles and a maximum discharge of 330 cubic feet per second, maintaining the integrity of Wiltcher Dam is crucial for the surrounding ecosystem and community.
Water resource and climate enthusiasts will find Wiltcher Dam to be an intriguing structure that plays a significant role in the local environment. As efforts are made to address its poor condition and mitigate potential risks, the dam continues to be a focal point for wildlife conservation and recreational activities in the area. With ongoing monitoring and maintenance, Wiltcher Dam stands as a testament to the importance of sustainable water management practices in the face of changing climate conditions.

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.
