Summary

Built in 2013 by Foundation Systems Engineering, this 30-foot tall earth dam serves primarily for recreational purposes, with a storage capacity of 28 acre-feet and a surface area of 1.6 acres. Despite not being state regulated or permitted, Jeansonne poses a high hazard potential due to its structural height of 30 feet and hydraulic height of 26 feet.

The dam, with an uncontrolled spillway type, has a moderate risk assessment rating of 3. Although its condition assessment is marked as "Not Rated," Jeansonne undergoes inspections every five years, with the last conducted in March 2019. With emergency action plans and risk management measures not specified, the dam's potential impact in the event of failure underscores the need for ongoing monitoring and maintenance to ensure the safety of those downstream and the surrounding environment.

Located within the jurisdiction of the Huntington District, Jeansonne's risk profile presents a critical area of focus for water resource and climate enthusiasts. As a privately owned structure with no federal oversight, the dam highlights the importance of robust regulatory frameworks and proactive risk management strategies in safeguarding communities and ecosystems dependent on water resources in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
