Summary
Completed in 1950, this dam serves a primary purpose of "Other" and has a storage capacity of 270 acre-feet. It is regulated by the Oklahoma Water Resources Board and has state jurisdiction, permitting, inspection, and enforcement in place.
The dam, situated on TR-Clear Creek, has a controlled spillway and a low hazard potential. Although its condition assessment is currently not rated, it has a very high risk assessment level. With only one valve outlet gate, the dam has a maximum discharge capacity of 350 cubic feet per second. Despite being last inspected in 2003, it is subject to regular inspections every 5 years to ensure safety and compliance with regulatory standards.
Overall, Oknoname 113113 presents an interesting case study for water resource and climate enthusiasts. With its unique design features, storage capacity, and risk assessment, this dam serves as a critical infrastructure component in managing water resources in Osage County. As we continue to monitor and assess the impacts of climate change on water infrastructure, understanding the intricacies of dams like Oknoname 113113 becomes increasingly important for ensuring the resilience and sustainability of our water systems.

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.
