Summary
Standing at a height of 24 feet and with a storage capacity of 112 acre-feet, the dam creates a surface area of 12.9 acres for water enthusiasts to enjoy. Despite its low hazard potential, the dam's condition has not been rated, and there is no information available on its inspection frequency or emergency preparedness measures.
Situated on the Red River-Os, the dam is managed by private owners and does not fall under state jurisdiction or regulation. The lack of federal funding or agency involvement in its design, construction, or maintenance suggests that the responsibility for the dam's upkeep lies solely with its owners. With its primary purpose being recreation, Lake Jew Jon Upper Dam offers a tranquil setting for outdoor activities, although its risk assessment, emergency response plans, and management measures remain unclear.
Overall, Lake Jew Jon Upper Dam serves as a picturesque spot in Lafayette, Arkansas, where visitors can indulge in water-based recreational activities. While its low hazard potential may offer a sense of security, the dam's lack of official assessments and regulations raises questions about its long-term safety and maintenance practices. As water resource and climate enthusiasts, it is essential to advocate for proper monitoring and management of dams like Lake Jew Jon Upper to ensure the safety of both the structure and the surrounding environment.

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.
