Summary
This Earth-type dam, with a height of 35 feet and a length of 250 feet, serves as a critical water resource along the Salt Fork River Red River. With a storage capacity of 124 acre-feet and a drainage area of 0.9 square miles, Pence Kent plays a vital role in managing water flow and mitigating potential flood risks in the region.
Managed and regulated by the Oklahoma Water Resources Board (OWRB), Pence Kent is classified as a low hazard potential dam with a very high risk assessment rating. Despite its age, the dam remains in good condition, with regular inspections and operational checks ensuring its structural integrity. The presence of a controlled spillway, outlet gates, and a valve system further enhances the dam's safety and functionality, providing additional protection for downstream communities in the event of an emergency.
As a key component in the water infrastructure of the area, Pence Kent underscores the importance of proper dam management and maintenance in safeguarding against potential water-related hazards. With its strategic location and design features, this dam exemplifies the critical role that water resource management plays in ensuring the resilience of communities and ecosystems in the face of climate variability and change.

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.
