Summary
This dam serves as a flood risk reduction structure along the TR-Barnitz Creek, with a maximum storage capacity of 1576 acre-feet and a normal storage of 424 acre-feet. The dam stands at a height of 40 feet with a hydraulic height of 33 feet, spanning a length of 1300 feet and covering a surface area of 53 acres.
Despite being classified as low hazard potential, the SCS-Barnitz Creek Site-061 poses a very high risk factor (1) according to the data provided. The dam is equipped with a controlled spillway and a single valve outlet gate. While the last inspection date is recorded as January 1, 1980, the inspection frequency is set at 5 years, indicating a need for updated assessments to ensure the structural integrity and safety of the dam. The dam is under state enforcement and regulatory oversight by the Oklahoma Water Resources Board, with state permitting and inspection processes in place.
For water resource and climate enthusiasts, the SCS-Barnitz Creek Site-061 presents an intriguing case study in dam infrastructure management and risk assessment. With its historical significance and critical role in flood risk reduction, this earth dam in the Tulsa District serves as a focal point for understanding the complexities of water resource management in Oklahoma. As the dam continues to age, there is a growing need for proactive monitoring and maintenance to mitigate potential risks and ensure the continued effectiveness of this important water control structure.

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.
