Summary
Built in 1961 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along the TR-Clear Boggy Creek. Standing at a height of 22 feet and a length of 920 feet, it has a storage capacity of 184 acre-feet and a surface area of 6 acres.
Managed by the OWRB, this dam features a controlled spillway and a single valve outlet gate. Despite being classified as low hazard potential, the risk assessment for SCS-Upper Clear Boggy Creek Site-02 indicates a very high risk level, warranting attention to ensure its continued safety and functionality. While last inspected in 1980, with a scheduled inspection frequency of 5 years, the dam's condition assessment is currently listed as "Not Rated".
Water resource and climate enthusiasts would find SCS-Upper Clear Boggy Creek Site-02 to be an intriguing case study in flood mitigation infrastructure. With a history dating back to the early 1960s, this earth dam continues to play a crucial role in managing the water flow along TR-Clear Boggy Creek. As discussions around water resource management and climate resilience gain prominence, understanding the design, purpose, and risk profile of structures like this dam becomes increasingly relevant for informed decision-making and policy development.

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.
