Summary
Built in 2000 by USDA NRCS, this stone-core dam stands at a height of 29.8 feet and has a maximum storage capacity of 55 acre-feet. With a surface area of 180 acres and a drainage area of the same size, this dam serves multiple purposes and is regulated by the Oklahoma Water Resources Board.
Despite being categorized as low hazard potential, Oknoname 30141 is deemed to have a very high risk due to its location and structural attributes. While the dam's condition is currently not rated, it undergoes inspection every five years to ensure its continued functionality and safety. With controlled spillways and a history of state permitting and inspection, this dam plays a crucial role in managing water resources in Payne County and beyond.
For water resource and climate enthusiasts, Oknoname 30141 presents an intriguing case study of a privately owned dam in Oklahoma. With its unique design and regulatory framework, this structure highlights the intersection of infrastructure, environmental stewardship, and risk management in the realm of water conservation and management.

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.
