Summary

Built in 1957, this dam stands at a height of 38 feet and has a hydraulic height of 33 feet, providing a maximum storage capacity of 317 acre-feet. With a controlled spillway type and a maximum discharge of 2785 cubic feet per second, this dam serves as a crucial infrastructure for managing water resources in the area.

Despite being last inspected in 1980, this low hazard potential dam is still in good condition, albeit not officially rated. The dam's very high risk assessment rating highlights the importance of implementing effective risk management measures to ensure its continued safety and functionality. With a single valve outlet gate and a surface area of 42 acres, SCS-Barnitz Creek Site-066 plays a vital role in protecting the surrounding area from the adverse impacts of flooding and demonstrates the commitment of the state of Oklahoma to water resource management and climate resilience.

As part of the larger network of flood risk reduction infrastructure in the region, SCS-Barnitz Creek Site-066 stands as a testament to the collaboration between state and federal agencies in addressing water resource challenges. With its stone core and soil foundation, this earth dam represents a significant investment in water infrastructure with a focus on long-term sustainability. As water resource and climate enthusiasts, understanding and monitoring the condition of dams like SCS-Barnitz Creek Site-066 is essential for ensuring the resilience of our communities in the face of changing environmental conditions.

Dam Data Reference

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.
