Summary

Standing at a height of 14 feet with a hydraulic height matching that, the dam spans a length of 550 feet and has a storage capacity of 124 acre-feet, primarily utilized for irrigation purposes. Despite its significant hazard potential, the dam's condition remains unrated, with no recent inspections or maintenance reported.

Managed by private owners, Lake Jeanette Dam falls outside state jurisdiction and regulation, operating without state permitting, inspection, or enforcement. Although designated for irrigation, the dam's specific purposes and design cater to water resource management in the region. Located in Conway, Arkansas, the dam is a vital component in the local water infrastructure, serving the agricultural community by providing essential water resources for irrigation needs.

With no associated locks or spillways, Lake Jeanette Dam's risk management measures, emergency action plans, and hazard assessments remain unreported, leaving its current risk status relatively unknown. As an earth dam, its structural integrity and maintenance are crucial for ensuring the safety and security of the surrounding area, underscoring the importance of regular inspections and upkeep to prevent potential hazards and ensure continued water resource availability for 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.
