Summary

Completed in 1959, this dam stands at a height of 48 feet and has a hydraulic height of 43 feet, providing a maximum storage capacity of 133 acre-feet and normal storage of 105 acre-feet. With a surface area of 15 acres and a length of 980 feet, the dam plays a crucial role in managing floodwaters in the area, with a controlled spillway and valve outlet gates to regulate water flow.

Despite its low hazard potential, SCS-Barnitz Creek Site-065 is categorized as having a very high risk due to its age and lack of recent condition assessments. The dam has not been inspected since January 1, 1980, with an inspection frequency of 5 years. While emergency action plans and risk management measures are not currently in place, the dam's regulatory agency, OWRB, oversees state permitting, inspection, and enforcement to ensure its continued safety and functionality. As an essential flood control structure in the Tulsa District, this dam serves as a key component of water resource management in the region, highlighting the importance of regular maintenance and updates to mitigate potential risks.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
