Summary
Built in 1970, this Earth dam stands at 22 feet high and has a storage capacity of 130 acre-feet. Despite being classified as low hazard potential, it is considered to have a very high risk assessment due to its age and condition assessment not being rated.
Managed by the Oklahoma Water Resources Board (OWRB), Osborn Oj is equipped with a controlled spillway and a single valve outlet gate. While it has not undergone any recent modifications or assessments, the dam is subject to state regulation, inspection, and enforcement to ensure its safety and compliance with regulatory standards. Though currently in a state of disrepair, this structure serves a vital purpose in managing water resources in the region, highlighting the importance of monitoring and maintaining dams for sustainable water management practices.
For water resource and climate enthusiasts, Osborn Oj presents an intriguing case study of a privately-owned dam in Oklahoma. With its unique design features and historical significance, this structure embodies the intersection of human intervention and natural systems in water management. As efforts continue to assess and mitigate risks associated with aging infrastructure, Osborn Oj serves as a reminder of the ongoing challenges and opportunities in safeguarding our water resources for future generations.

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.
