Summary
The dam, situated on Sand Creek, serves as an essential water resource for the region, with a storage capacity of 51 acre-feet and a surface area of 3 acres. Despite its low hazard potential and moderate risk assessment rating, the dam's condition remains unrated, highlighting the need for further evaluation and potential risk management measures to ensure its long-term stability and functionality.
With a dam height of 28 feet and a length of 298 feet, the Ruble Gp #6 dam features an uncontrolled spillway with a width of 67 feet. While the dam has not undergone recent inspections, its emergency action plan status and risk management measures are currently unspecified. The dam's proximity to Fort Supply and its critical role in water storage and management underscore the importance of continued monitoring and maintenance to safeguard against potential hazards and ensure its resilience in the face of changing climate conditions.
As water resource and climate enthusiasts, it is crucial to recognize the significance of structures like the Ruble Gp #6 dam in sustaining local ecosystems and communities. By staying informed about the dam's condition, risk assessment, and emergency preparedness, stakeholders can work towards implementing effective risk management measures and ensuring the long-term viability of this vital water resource infrastructure in Oklahoma.

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.
