Summary

Completed in 1925, this earth dam stands at 17 feet high and spans 304 feet in length, creating a reservoir with a storage capacity of 63 acre-feet. The dam is situated on a tributary to Spring Creek and is regulated by the Oklahoma Water Resources Board, with state permitting, inspection, and enforcement in place to ensure its safety and compliance with regulations.

Despite its recreational focus, Pines East poses a high hazard potential, with an unsatisfactory condition assessment as of December 2021. The dam features a controlled spillway and a single valve outlet gate, with a maximum discharge capacity of 500 cubic feet per second. The risk assessment for Pines East rates its risk level as very high, emphasizing the need for ongoing risk management measures to mitigate potential hazards and uphold public safety. As water resource and climate enthusiasts, it is crucial to monitor the condition of dams like Pines East to ensure their resilience in the face of changing environmental conditions.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
