Summary
Completed in 1970, this earth dam stands at a height of 31 feet and has a hydraulic height of 25 feet, serving as a crucial structure along Keechi Creek in Caddo County. With a normal storage capacity of 406 acre-feet and a maximum storage of 1466 acre-feet, this dam plays a vital role in managing water resources in the region.
Despite being categorized as low hazard potential, SCS-Sugar Creek Site-004 is considered to have a very high risk assessment, highlighting the importance of ongoing monitoring and maintenance. Although the condition assessment is currently marked as 'Not Rated', the dam has not been inspected since January 1980, emphasizing the need for regular inspections to ensure its structural integrity and effectiveness in flood risk reduction. With a controlled spillway and one outlet valve, this dam is equipped to manage maximum discharges of up to 5130 cubic feet per second, safeguarding the surrounding community from potential flooding events.
As a key component in the flood risk reduction infrastructure in Oklahoma, SCS-Sugar Creek Site-004 serves as a critical line of defense against flooding along Keechi Creek. With its stone core and soil foundation, this dam stands as a testament to the importance of water resource management and climate resilience efforts in the region. As the dam enters its fifth decade of operation, continued attention to maintenance and risk management measures will be essential to ensure its long-term effectiveness in protecting the local community from the impacts of extreme weather events.

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.
