Summary

Built in 1961, this dam stands at a structural height of 40.6 feet and has a hydraulic height of 37.1 feet, with a total length of 723 feet. The dam has a storage capacity of 434 acre-feet and serves the purpose of regulating the flow of TribScotts Creek.

Despite being classified as a high-hazard potential structure with a moderate risk assessment, Bob's #1 has not been rated for its condition. The dam has not undergone recent inspections, with the last one taking place in January 2017. While there are no associated locks or spillways with the structure, it is crucial to ensure regular maintenance and monitoring to prevent any potential risks or hazards. Water resource and climate enthusiasts should keep a close eye on the status of Bob's #1 and advocate for necessary safety measures to protect the surrounding community and environment.

In the event of an emergency, it is important for the owners of Bob's #1 to have an Emergency Action Plan (EAP) in place to mitigate any potential risks or threats. With a lack of detailed risk management measures and assessment summaries, there is room for improvement in ensuring the safety and stability of this dam. Continued oversight and proactive measures will be essential to safeguard the integrity of Bob's #1 and uphold the critical role it plays in water resource management in the region.

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.
