Summary
Completed in 1962, this earth dam stands at a height of 45 feet and has a storage capacity of 540 acre-feet. The dam's spillway type is controlled, with a spillway width of 1 foot, and it is equipped with a valve outlet gate for water release.
This significant dam, with a hazard potential categorized as "Significant" and a condition assessment of "Fair," has a very high risk rating. Despite its fair condition, the dam meets inspection, permitting, and enforcement requirements set by the state regulatory agency (OWRB). The dam's location in the city of AHLOSO along TR-Clear Boggy Creek underscores its crucial role in managing water resources and mitigating flood risks in the area.
Water resource and climate enthusiasts will appreciate the detailed information about SCS-Upper Clear Boggy Creek Site-40, including its design, construction, storage capacity, and risk assessment. With its historical significance and impact on flood risk reduction in Pontotoc, Oklahoma, this dam serves as a vital infrastructure managed by state authorities to ensure the safety and resilience of the surrounding community.

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.
