Summary
With a dam height of 33 feet and a length of 1100 feet, this structure has a maximum storage capacity of 554 acre-feet and serves a drainage area of 2.28 square miles. The dam features a controlled spillway and a single valve outlet gate for water release.
Despite its low hazard potential, the SCS-Lower Clear Boggy Creek Site-26 has been rated as having a very high risk of failure, emphasizing the importance of regular inspections and maintenance. The condition assessment is currently listed as "Not Rated," with the last inspection date recorded as January 1, 1980. The dam's emergency action plan (EAP) status, risk management measures, and inundation maps are all listed as unknown, indicating potential areas for improvement in emergency preparedness.
Given the critical role this dam plays in flood risk reduction in the area, it is essential for the relevant state agencies, such as OWRB, to ensure regular inspections and enforcement measures are in place to mitigate the identified high risk. Climate and water resource enthusiasts may find interest in the unique design and operational aspects of the SCS-Lower Clear Boggy Creek Site-26, as well as the need for continued monitoring and maintenance to safeguard surrounding communities from potential flooding 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.
