Summary
Built in 1962 by the USDA NRCS, this dam stands at a height of 30 feet and has a normal storage capacity of 25 acre-feet. With a controlled spillway and a maximum discharge of 343 cubic feet per second, this dam serves a variety of purposes beyond flood control, making it a valuable water resource for the surrounding community.
Despite being rated as having a low hazard potential, Randall No.10 is considered to have a very high risk due to its condition assessment being labeled as "not rated." The dam's emergency action plan status is unknown, and it lacks updated inundation maps and emergency contact information. With its risk management measures and overall risk assessment yet to be determined, there is a need for increased monitoring and possible improvements to ensure the safety and functionality of this essential water infrastructure.
In the hands of a private owner, Randall No.10 plays a crucial role in water management in Harper County, Oklahoma. As climate change continues to impact the region, maintaining and enhancing the resilience of this dam will be vital in safeguarding water resources and mitigating potential risks for the local community and ecosystem.

Dam Data Reference
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.
