Summary

This earth dam rises 13 feet high and spans 210 feet in length, providing a storage capacity of 105 acre-feet for recreational use. With a spillway type labeled as "uncontrolled" and uncontrolled outlet gates, the dam's hazard potential is considered low, and its condition assessment remains unrated.

Despite not being state-regulated, Upper Bond Lake Dam undergoes regular inspections, with the last one dated back to September 2018. The dam's risk assessment is moderate, indicating a potential for hazards that require appropriate management measures. While the dam does not have an Emergency Action Plan (EAP) in place or updated emergency contacts, its risk level suggests the need for proactive monitoring and safety measures to ensure the surrounding area remains protected from potential risks associated with the dam's operations. As an integral part of the local water resource and climate landscape, Upper Bond Lake Dam serves as a recreational haven with a unique blend of natural beauty and engineered infrastructure.

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.
