Summary
The earth dam stands at a height of 23 feet with a length of 1800 feet, providing a storage capacity of 757 acre-feet. The dam is situated on TR-SANDY CREEK in the Tulsa District, with a controlled spillway and a valve outlet gate for release.
This dam has a high hazard potential and is assessed to be in fair condition, with a very high risk rating. Despite being classified as fair, the dam is inspected regularly, with the last recorded inspection in 2011. The dam is under the jurisdiction of OWRB and has state permitting, inspection, and enforcement mechanisms in place to ensure safety and compliance. The risk assessment for this dam site indicates a very high risk level, highlighting the importance of proper management and maintenance to mitigate potential hazards.
Overall, SCS-Leader-Mid Clr Boggy Cr Site-26a serves a crucial function in managing flood risks in the region and is a significant water resource infrastructure in Oklahoma. With its strategic location and design, this dam plays a vital role in protecting communities and properties from flooding events. It serves as a reminder of the importance of sustainable water resource management and climate resilience in the face of changing weather patterns and increasing risks of extreme 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.
