Summary
Constructed in 2001 by the USDA NRCS, this dam stands at a height of 23.8 feet and has a storage capacity of 105.09 acre-feet. With a controlled spillway and a single valve outlet gate, this dam serves a primary purpose of "Other" and is regulated by the Oklahoma Water Resources Board.
Despite being rated as having a low hazard potential, Oknoname 30050 is considered to have a very high risk due to its condition assessment being "Not Rated." The dam has not been inspected since November 2010, and the risk management measures and emergency action plan status remain unclear. With a drainage area of 1070 acres, this dam plays a crucial role in water resource management in the region and presents an opportunity for further evaluation and potential improvements to ensure its safety and effectiveness in the face of changing climate conditions.
Water resource and climate enthusiasts will find Oknoname 30050 to be an intriguing case study for understanding the intersection of infrastructure, regulation, and risk management in the context of water resource management. As a privately owned structure with state jurisdiction and involvement from federal agencies like the Natural Resources Conservation Service, this dam showcases the complexities and challenges of managing water resources in a changing environment. With a focus on safety, maintenance, and preparedness, Oknoname 30050 highlights the importance of proactive approaches to ensure the resilience of our water infrastructure in the face of climate-related risks.

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.
