Summary
Completed in 1967, this earth dam stands at a height of 31 feet and has a hydraulic height of 25 feet, providing critical protection to the surrounding area along Kohnoosky Creek. With a significant hazard potential and a fair condition assessment, this dam plays a crucial role in mitigating flood risks in the region.
Owned by the state of Oklahoma and regulated by the OWRB, SCS-Sugar Creek Site-025 has a normal storage capacity of 188 acre-feet and a maximum storage of 621 acre-feet. The dam features a controlled spillway and a single valve outlet gate for water release. Despite its fair condition, the dam has a very high risk assessment rating, highlighting the importance of regular inspections and maintenance to ensure its continued effectiveness in flood risk reduction.
With a risk management plan yet to be fully detailed and a last inspection date in 2011, SCS-Sugar Creek Site-025 presents an opportunity for enhanced emergency preparedness and risk mitigation measures. As climate change continues to impact water resources and increase the frequency and intensity of extreme weather events, the role of dams like SCS-Sugar Creek Site-025 in protecting communities from flooding becomes ever more crucial.

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.
