Summary
Completed in 1978, this dam stands at a height of 35 feet and has a hydraulic height of 31 feet, providing storage capacity of 1009 acre-feet with a normal storage level of 644 acre-feet. The dam's controlled spillway, with a width of 2 feet, helps manage excess water flow during heavy rainfall events.
Despite being classified as having a low hazard potential, SCS-Upper Muddy Boggy Creek Site-20 is rated as having a very high risk due to its condition assessment not being rated. Emergency action plans and inundation maps have not been prepared for this site, highlighting potential gaps in risk management. With state inspection, regulation, and enforcement in place, there is an opportunity to enhance the safety and resilience of this dam through regular assessments and updates to emergency preparedness protocols.
As an important infrastructure for flood risk reduction in the Tulsa District, SCS-Upper Muddy Boggy Creek Site-20 serves as a critical component of water resource management in the region. With attention to maintenance, monitoring, and risk mitigation measures, this dam can continue to fulfill its primary purpose effectively while ensuring the safety of surrounding communities and the environment.

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.
