Summary
Completed in 1950, this dam on TR-SALT CREEK stands at a height of 26 feet and has a maximum storage capacity of 195 acre-feet. The dam's primary purpose is listed as "Other", with a spillway type of "Controlled" and a low hazard potential rating.
Managed by the Oklahoma Water Resources Board (OWRB), Oknoname 113146 has been deemed to have a very high risk level, with a risk assessment rating of 1. The dam has one valve outlet gate and is subject to state regulation, permitting, inspection, and enforcement. Despite its age, the dam's condition assessment is listed as "Not Rated", and the last inspection date was in November 2001. The dam does not have an Emergency Action Plan (EAP) in place.
Located in the Tulsa District, Oknoname 113146 is a significant structure in the region, with a history dating back to the mid-20th century. Enthusiasts of water resources and climate will find this dam's data and risk assessment to be of interest, especially considering its high-risk classification and the potential implications for the surrounding area in the event of a breach or failure.

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.
