Summary
is a private water resource infrastructure located in Coxs Corner, Oklahoma, along TR-Beaver Creek. Built in 1963, this Earth-type dam stands at a height of 30 feet and has a storage capacity of 180 acre-feet. Despite its low hazard potential, the dam is regulated by the state agency OWRB and undergoes regular inspections to ensure its safety and compliance with state regulations.
The dam features a controlled spillway and a single valve outlet gate, with a maximum discharge capacity of 1100 cubic feet per second. Although it has not been assessed for condition, the risk management measures in place suggest a high level of preparedness in case of emergencies. The surrounding area has a very high risk assessment rating, indicating the importance of maintaining the dam's integrity and functionality to protect downstream communities and the local environment.
With its strategic location in the Tulsa District and close proximity to Coxs Corner, Jacobi A.G. serves as a crucial water management structure in Comanche County, Oklahoma. Its operational status, state permitting, and enforcement of regulations ensure that this dam continues to play a vital role in water resource management and climate resilience efforts in the region.

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.
