Summary
Standing at a height of 39 feet with a length of 194 feet, this dam has a storage capacity of 71 acre-feet and serves the primary purpose of water resource management. Situated on Sand Creek in FORT SUPPLY, this structure plays a crucial role in regulating water flow and providing flood protection in the area.
With a low hazard potential and a moderate risk assessment rating, Ruble Gp #5 has not been recently inspected or assessed for its condition. Despite the lack of a formal emergency action plan and inundation maps, this dam continues to serve its intended purpose effectively. The presence of an uncontrolled spillway with a width of 52 feet ensures the safe release of excess water during periods of heavy rainfall or flooding, further enhancing the dam's resilience and functionality.
As a vital component of the water infrastructure in the region, Ruble Gp #5 showcases the importance of proper dam maintenance and risk management practices. With its historical significance and ongoing role in water resource management, this dam serves as a reminder of the essential connection between infrastructure, climate resilience, and community safety.

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.
