Summary
The dam is privately owned and stands at a height of 10.8 feet with a storage capacity of 126 acre-feet. With a low hazard potential and a moderate risk assessment rating, Thompson Lake Dam plays a crucial role in water resource management in Baker County.
Despite being unregulated by the state, Thompson Lake Dam undergoes regular inspections every five years to ensure its structural integrity and safety. The dam features an uncontrolled spillway and outlet gates, contributing to its low hazard potential. The surrounding area has a drainage area of 730 acres, with a surface area of 16 acres, making it a significant water resource for the region. With its strategic location and essential functions, Thompson Lake Dam is a vital piece of infrastructure for both water conservation and climate sustainability efforts in the area.
Although not rated for its condition, Thompson Lake Dam remains an integral part of the local ecosystem, providing water storage, fire protection, and recreational opportunities for the community. With a risk management plan in place and regular inspections, the dam continues to serve its purpose effectively while mitigating potential hazards. As climate change impacts water resources, the importance of structures like Thompson Lake Dam in sustainable water management practices becomes increasingly apparent, emphasizing the need for continued monitoring and maintenance to ensure its long-term functionality.

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.
