Summary
This dam, standing at a height of 28.7 feet, serves a primary purpose of "Other" and is regulated by the Oklahoma Water Resources Board. The dam's structure is primarily made of stone with a soil foundation, and it spans 110 feet in length with a storage capacity of 23.5 acre-feet.
Despite being categorized as low hazard, Oknoname 30130 poses a very high risk according to a risk assessment, indicating the potential for significant consequences in the event of failure. The dam features a controlled spillway and a single valve outlet gate. While it has not been rated for condition assessment, it undergoes inspections every five years, with the last inspection conducted in August 2011. The dam's location on an unnamed tributary of Bear Creek in Meridian, alongside its proximity to residential areas, emphasizes the importance of continued monitoring and maintenance to ensure the safety of surrounding communities and water resources.
Water resource and climate enthusiasts will find Oknoname 30130 to be a noteworthy structure within the Tulsa District of Oklahoma. Its construction and regulatory history, along with its unique design and risk factors, present a valuable case study for understanding the complexities of managing and maintaining dams in the face of changing environmental conditions. As the debate around water resource management and climate resilience continues to evolve, Oknoname 30130 stands as a reminder of the crucial role that infrastructure plays in safeguarding our communities and natural landscapes.

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.
