Summary
Constructed in 1978 by the USDA NRCS, this dam stands at a height of 28 feet and has a maximum storage capacity of 60 acre-feet. With a controlled spillway type and a valve outlet gate, Kouns No 1 has a low hazard potential and a very high risk assessment rating of 1.
Managed by the Oklahoma Water Resources Board (OWRB), Kouns No 1 is inspected every five years, with the last inspection conducted in June 2005. Although its condition assessment is currently not rated, the dam is deemed to meet regulatory standards and is equipped with emergency action plans (EAP) for potential risk management. Despite its relatively remote location in TALOGA, Kouns No 1 plays a crucial role in protecting the surrounding area from potential flooding events and ensuring water resource sustainability in the region.
With its stone core and soil foundation, Kouns No 1 serves as a vital infrastructure for flood control and water management in the Tulsa District. Supported by the Natural Resources Conservation Service and designed for long-term resilience, this dam exemplifies the importance of proactive climate adaptation measures in safeguarding water resources for future generations.

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.
