Summary
Built by the USDA NRCS in 1967, this dam serves the primary purpose of flood risk reduction and stands at a height of 29 feet with a hydraulic height of 26 feet. With a storage capacity of 795 acre-feet, the dam has a controlled spillway and one outlet valve.
Despite being rated as having a low hazard potential, SCS-Leader-Mid Clr Boggy Cr Site-21 is considered to have a very high risk level according to the data provided. The dam has not been assessed for its condition and has not had a formal emergency action plan prepared. The last inspection took place in 1980, with a recommended inspection frequency of every 5 years. The dam remains under state jurisdiction and is subject to state regulation, inspection, and enforcement by the Oklahoma Water Resources Board.
Water resource and climate enthusiasts may find SCS-Leader-Mid Clr Boggy Cr Site-21 to be an intriguing case study of a state-owned dam designed for flood risk reduction. Despite its low hazard potential, the dam is categorized as having a very high risk level, highlighting the importance of regular inspections and emergency preparedness. As a part of the larger infrastructure managing water resources in the Tulsa District, this dam serves as a critical component in the region's flood control and water management efforts.

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.
