Summary
Jr. is a privately owned dam located in Stephens, Oklahoma, specifically in the city of Loco. Completed in 1975, this earth dam stands at a height of 21 feet with a hydraulic height of 15 feet. Its primary purpose is classified as 'Other', and it serves as a vital structure for water resource management in the area. The dam has a storage capacity of 69 acre-feet and a normal storage of 50 acre-feet, with a maximum discharge capacity of 2050 cubic feet per second.
The dam is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular inspections and enforcement to ensure its structural integrity and safety. Despite its low hazard potential, the risk assessment for Jackson J.E. Jr. has been classified as 'Very High (1)', indicating the importance of effective risk management measures. With a controlled spillway and one outlet valve, the dam plays a crucial role in managing water flow and mitigating potential flood risks along the TR Pine Creek.
Overall, Jackson J.E. Jr. stands as a significant infrastructure for water resource management in Oklahoma, providing essential services for both agricultural and community needs. As a privately owned structure, it is subject to state regulations and inspections to ensure its continued functionality and safety. The risk assessment highlights the importance of proactive risk management strategies to safeguard against potential hazards and maintain the dam's critical role in the local water ecosystem.

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.
