Summary
This structure stands at a height of 27 feet with a hydraulic height of 23 feet, serving its primary purpose effectively with a storage capacity of 100 acre-feet. With a controlled spillway and one outlet valve, Stobough No.1 has a low hazard potential and a very high risk assessment rating, making it a critical infrastructure in the region.
Managed by the OWRB, this dam in the Tulsa District plays a crucial role in regulating water flow and protecting the surrounding areas from potential flooding. Although last inspected in 2010, Stobough No.1 has not been rated for its current condition. Despite being privately owned, the dam is subject to state regulation, inspection, and enforcement, ensuring its continued safe operation and maintenance. With its strategic location and design, this dam exemplifies the importance of effective water resource management in mitigating climate-related risks.
For water resource and climate enthusiasts, Stobough No.1 serves as a prime example of how infrastructure like dams can play a vital role in flood risk reduction and water management strategies. The collaboration between private ownership, federal agencies like the NRCS, and state regulators like the OWRB showcases the multi-level approach required to ensure the resilience of water systems in the face of changing climate patterns. As efforts to assess and mitigate risks associated with dams like Stobough No.1 continue, it underscores the interconnectedness of water resources, infrastructure, and climate adaptation in safeguarding communities and ecosystems for the future.

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.
