Summary
Completed in 1961, this earth dam stands at a height of 22 feet and spans 1600 feet in length, providing a storage capacity of 448 acre-feet for flood control purposes. The dam features a controlled spillway and a single valve outlet gate for water release.
Despite being categorized as having a low hazard potential, SCS-Upper Clear Boggy Creek Site-18 is considered to have a very high risk level, potentially due to its age and condition assessment being labeled as "Not Rated." The last inspection was conducted in 1980, with an inspection frequency of every 5 years. While emergency action plans, risk assessments, and inundation maps are not currently prepared or updated for this dam, it remains under the jurisdiction of the OWRB for regulatory oversight, inspection, and enforcement to ensure public safety and environmental protection. As a key infrastructure for managing floodwaters in the region, continued monitoring and maintenance of this dam are essential to mitigate any potential risks and ensure its reliability in the face of changing climate conditions and water resource 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.
