Summary
Completed in 1956, this earth dam spans 700 feet and has a structural height of 11 feet, creating a reservoir with a maximum storage capacity of 134 acre-feet. Situated on the Little La Grue Bayou-TR, the dam serves primarily for recreational purposes, offering opportunities for fishing, boating, and wildlife observation in a serene natural setting.
Despite its low hazard potential and not yet rated condition assessment, Hillman Pond Dam underscores the need for ongoing monitoring and maintenance to ensure its continued safety and effectiveness. With a hydraulic height of 7 feet and a normal storage capacity of 70 acre-feet, the dam plays a vital role in water management and conservation efforts in the region. However, the lack of state regulation, inspection, and enforcement raises questions about the long-term sustainability and resilience of this critical infrastructure.
As climate change threatens to alter precipitation patterns and increase the frequency of extreme weather events, water resource and climate enthusiasts must advocate for the proper management and protection of dams like Hillman Pond Dam. By promoting responsible stewardship and investing in resilience measures, we can safeguard these essential structures for future generations to enjoy and benefit from.

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.
