Summary
Constructed in 1999 by the USDA NRCS, this earth dam stands at a height of 12.5 feet with a structural height of 10.5 feet, serving a primary purpose that is categorized as "Other." The dam has a storage capacity of 122.2 acre-feet, with a normal storage level of 28.1 acre-feet and a surface area of 12.5 acres.
Situated on Wolfe Creek, this dam plays a crucial role in regulating water flow and providing flood control in the area. With a controlled spillway type and a low hazard potential, Oknoname 30171 has a very high risk assessment ranking, indicating the importance of proper maintenance and monitoring. While the condition assessment is currently listed as "Not Rated," the dam is subject to regular inspections every five years, with the last inspection conducted in December 2010.
Managed by the OWRB and falling under the jurisdiction of the state of Oklahoma, Oknoname 30171 stands as a significant infrastructure for water resource management in the region. With its strategic location and design features, this dam serves as a vital component in ensuring water security and environmental stability in the surrounding area, making it a key asset for water resource and climate enthusiasts to monitor and study.

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.
