Summary
is a privately owned earth dam located in Garvin, Oklahoma, specifically along the TR-Washita River. Completed in 1955, this dam stands at a height of 25 feet and spans 300 feet in length, with a maximum storage capacity of 80 acre-feet. The primary purpose of Philpott C.M. is flood risk reduction, making it an important structure for managing water resources in the area.
Despite its age, Philpott C.M. is regularly inspected and maintained, with the last inspection conducted in May 2010. The dam has a low hazard potential and a very high risk assessment rating, indicating the importance of its continued monitoring and upkeep to ensure the safety of downstream communities. The dam features a controlled spillway and a single valve outlet gate, further enhancing its flood risk reduction capabilities.
Overall, Philpott C.M. serves as a vital component of water resource management in Garvin, Oklahoma, with its efficient design and strategic location along the TR-Washita River. As a privately owned structure regulated by the Oklahoma Water Resources Board, this dam plays a crucial role in reducing flood risks and protecting the surrounding area from potential water-related hazards. With its sturdy earth construction and ongoing inspections, Philpott C.M. exemplifies the importance of proactive measures in ensuring the resilience of water infrastructure in the face of climate challenges.

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.
