Summary
is a privately owned dam located in Cotton County, Oklahoma, near the city of Walters. Completed in 1971, this earth dam stands at a height of 28 feet and has a hydraulic height of 22 feet, with a total length of 380 feet. The dam serves as a crucial structure along TR Snake Creek, providing a maximum storage capacity of 55 acre-feet and a normal storage level of 44 acre-feet. With a controlled spillway and a low hazard potential, Phillips H.E. plays a vital role in managing water resources in the area.
Managed by the Oklahoma Water Resources Board, Phillips H.E. is regularly inspected and maintained to ensure its structural integrity and functionality. The dam features a single valve outlet gate for water release and has not been rated for its condition assessment. Despite the very high risk classification given to the dam, measures for risk management and emergency action planning have not been explicitly outlined in the available data. The surrounding community and local officials, including Congressman Tom Cole, are integral in ensuring the safety and sustainability of Phillips H.E. for both water resource management and climate resilience in the region.
In the realm of water resource and climate management, Phillips H.E. stands as a significant earth dam in Oklahoma, contributing to flood control, water storage, and environmental protection along TR Snake Creek. While the dam's risk potential is deemed very high, ongoing inspections and regulatory oversight by the Oklahoma Water Resources Board are vital in safeguarding the surrounding area from potential hazards. As efforts for risk assessment and emergency preparedness continue to evolve, Phillips H.E. remains a crucial infrastructure for sustainable water resource management and climate adaptation in Cotton County, Oklahoma.

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.
