Summary
Completed in 1962, this dam provides a storage capacity of 31 acre-feet and covers a surface area of 2 acres, serving a drainage area of 0.35 square miles. Despite its uncontrolled spillway type and low hazard potential, Ruble Gp 10 is classified with a moderate risk rating of 3, emphasizing the importance of ongoing risk management measures.
Managed by the USDA NRCS, Ruble Gp 10 is not subject to state regulation or inspection, highlighting its private ownership status. The dam's primary purpose and associated structures are unspecified, while its non-federal funding and design further underscore its private ownership and operation. With a congressman representative of Frank D. Lucas (R) and a risk assessment indicating moderate risk, Ruble Gp 10 stands as a significant water resource infrastructure in the region, warranting continued monitoring and maintenance to ensure its structural integrity and public safety.
Despite its age and condition assessment of "Not Rated," Ruble Gp 10 plays a crucial role in water management within the region, contributing to flood control and water storage along Sand Creek. As climate change continues to impact water resources, the need for sustainable infrastructure and risk management measures becomes increasingly paramount, emphasizing the importance of ongoing monitoring and maintenance for dams like Ruble Gp 10. With its historical significance and operational role, this earth dam structure serves as a focal point for water resource and climate enthusiasts seeking to understand the intersection of infrastructure, water management, and environmental resilience.

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.
