Summary

Built in 1960 by the USDA NRCS, this earth dam stands at a height of 35 feet and spans a length of 1430 feet. With a storage capacity of 1470 acre-feet and a controlled spillway, this dam serves as a vital infrastructure for managing water resources in the region.

Despite being classified with a low hazard potential, this dam has a very high risk assessment due to its age and the lack of recent condition assessments. The last inspection was conducted in 1980, emphasizing the importance of regular monitoring and maintenance to ensure the safety and effectiveness of the structure. With the state agency OWRB overseeing its regulation, inspection, and enforcement, the SCS-Upper Clear Boggy Creek Site-11 plays a crucial role in safeguarding the local community from potential flood events.

As water resource and climate enthusiasts, it is imperative to recognize the significance of dams like SCS-Upper Clear Boggy Creek Site-11 in protecting lives and properties from the impacts of extreme weather events. By advocating for regular inspections, maintenance, and risk management measures, we can ensure the resilience and sustainability of our water infrastructure for future generations.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
