Summary

Designed by the USDA NRCS, this dam is regulated by the OWRB and has state permitting, inspection, and enforcement in place. Situated on an unnamed tributary of Stillwater Creek, this dam stands at a height of 24.1 feet and has a hydraulic height of 21.1 feet, with a structural height of 27.1 feet.

With a storage capacity of 184.7 acre-feet and a surface area of 10.3 acres, Oknoname 30210 serves a primary purpose that is categorized as 'Other'. The dam is of stone core type with a soil foundation and a controlled spillway. Although its hazard potential is considered low, the risk assessment for this structure is very high, indicating the need for proper risk management measures to be put in place. Despite not having a condition rating, this dam is subject to regular inspections every 5 years.

Overall, Oknoname 30210 is a notable water resource in Oklahoma that plays a crucial role in water management and flood control. For water resource and climate enthusiasts, this dam presents an interesting case study in dam regulation, risk assessment, and the importance of maintaining infrastructure to ensure public safety and environmental protection.

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.
