Summary

This earth dam stands at a height of 27 feet with a hydraulic height of 24 feet, providing a storage capacity of 50 acre-feet and a surface area of 4 acres. The dam features a controlled spillway with a width of 1 foot and a single valve outlet gate.

Despite its low hazard potential and current condition assessment being not rated, the dam at SCS-Sugar Creek Site-101 poses a very high risk due to its age and the lack of recent inspections. The dam is under the jurisdiction of the Oklahoma Water Resources Board and is subject to state permitting, inspection, and enforcement. The primary purpose of the dam is flood risk reduction, serving as a key infrastructure for protecting the surrounding area from potential flood events.

With its historical significance and critical role in managing water resources in the region, SCS-Sugar Creek Site-101 stands as a testament to the importance of proper dam maintenance and risk management. As climate change continues to impact weather patterns and increase the frequency of extreme events, the need for robust infrastructure like this dam becomes more pressing. Water resource and climate enthusiasts will find this site to be a valuable case study in understanding the intersection of infrastructure, environmental protection, and community resilience in the face of a changing climate.

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.
