Summary
Built in 1915, this earth dam stands at a hydraulic height of 35 feet, with a structural height of 25 feet and a length of 600 feet. The reservoir has a storage capacity of 30 acre-feet, with a normal storage level of 28 acre-feet, serving the primary purpose of water supply for the region.
Despite its historical significance, Fairview Reservoir No 1 is currently facing challenges, with a poor condition assessment and a high hazard potential. The last inspection in March 2018 highlighted the need for improvements and regular monitoring due to its critical role in the local water supply system. The reservoir is regulated by the Washington Dept of Ecology, ensuring compliance with state permitting, inspection, and enforcement requirements to maintain its operational integrity and public safety.
As water resource and climate enthusiasts, the conservation and maintenance of Fairview Reservoir No 1 are essential to ensure a reliable water supply for the community. Stakeholders, including the local government and regulatory agencies, must work together to address the dam's poor condition and implement risk management measures to mitigate potential hazards. By investing in the infrastructure and implementing necessary upgrades, Fairview Reservoir No 1 can continue to serve its vital role in water supply while safeguarding against potential risks and ensuring long-term sustainability.

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.
