Summary

is a privately owned dam located in Coxs Corner, Oklahoma, specifically on TR-Cottonwood Cr. The dam, completed in 1965, stands at a height of 18 feet and has a storage capacity of 50 acre-feet. It serves a primary purpose of "Other" and is classified as an Earth dam with a stone core and soil foundation. The dam has a controlled spillway type with a width of 1 foot and features a single valve outlet gate.

Despite being rated as having a low hazard potential, White G.C. is considered to have a very high risk due to its location and potential impacts on the surrounding area in case of failure. The dam is under state regulation by the Oklahoma Water Resources Board (OWRB) and is subject to regular inspections, with the last inspection conducted in September 2010. It is important for water resource and climate enthusiasts to monitor White G.C. closely to ensure its continued safety and integrity for the community it serves in Comanche County, Oklahoma.

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.
