Summary
is a privately owned earth dam on the TR-RANCH CR river, with a height of 17 feet and a length of 1000 feet. Completed in 1930, this dam serves multiple purposes and has a maximum storage capacity of 50 acre-feet. The dam is regulated and inspected by the Oklahoma Water Resources Board, ensuring its safety and compliance with state regulations.
With a low hazard potential and a "Very High (1)" risk assessment rating, Jeffrey Glen R. is a crucial structure in the region's water resource management. The dam features a controlled spillway and a single valve outlet gate for water release. Despite its age, the dam has not been rated for its current condition, highlighting the importance of regular inspections and maintenance to ensure its continued functionality.
Even though Jeffrey Glen R. poses a low hazard, its very high risk assessment underscores the need for proactive risk management measures. With the potential to impact the surrounding area in the event of failure, the dam requires regular monitoring and adherence to emergency action plans. As a key component of the water infrastructure in the region, Jeffrey Glen R. serves as a reminder of the importance of maintaining and regulating dams for both water resource and climate resilience.

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.
