Summary
Completed in 1986, this flood risk reduction structure stands at a height of 39 feet and has a length of 2080 feet, providing a storage capacity of 2027 acre-feet. The dam is primarily used for flood risk reduction and is under the jurisdiction of the Oklahoma Water Resources Board.
With a drainage area of 4.4 square miles and a maximum discharge of 2465 cubic feet per second, SCS-Lower Clear Boggy Creek Site-16 plays a crucial role in managing water resources in the region. The dam features a controlled spillway and one outlet valve, with a low hazard potential rating and a very high risk assessment due to its important function in flood control. Despite being last inspected in 1980, the structure's condition remains unassessed, highlighting the need for regular maintenance and monitoring to ensure its effectiveness in mitigating flood risks.
For water resource and climate enthusiasts, SCS-Lower Clear Boggy Creek Site-16 serves as a fascinating example of how engineering solutions like earth dams are utilized to manage water flow and reduce the impact of floods on communities. Its location in a natural setting along Sandy Creek, combined with its design features and operational aspects, offer valuable insights into the intersection of infrastructure, water management, and environmental stewardship. The dam's role in protecting downstream areas and providing critical storage capacity underscores the importance of sustainable water resource management practices in addressing climate-related challenges.

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.
