Summary
The dam's spillway type is controlled, with a spillway width of 2 feet, and it is rated as having low hazard potential.
Managed by the Oklahoma Water Resources Board, Oknoname 113108 is subject to state regulation, permitting, inspection, and enforcement. The dam is situated on the TR-BUG CR river or stream, within the Tulsa District of Oklahoma. Despite its very high risk assessment rating, the dam's condition is currently listed as "Not Rated," indicating a need for further evaluation to ensure its safety and functionality in the face of potential climate-related challenges.
With a surface area of 6 acres and an outlet gate consisting of a single valve, Oknoname 113108 serves as a crucial water resource for the surrounding area. As climate change continues to impact water availability and quality, monitoring and maintaining the integrity of dams like Oknoname 113108 are essential for safeguarding communities and ecosystems against the threats of flooding and water scarcity.

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.
