Fairfield Sewage Aerated Lagoon - Lagoon 1 dam
Fairfield Sewage Aerated Lagoon - Lagoon 1
Fairfield Sewage Aerated Lagoon - Lagoon 1, located in Spokane, Washington, is a crucial water resource managed by the local government with oversight from the Washington Dept of Ecology. This lagoon, constructed in 2003 by Century West Engineering, serves as a key component in the treatment of sewage and wastewater in the area. With a hydraulic height of 13.4 feet and a structural height of 12 feet, this earth dam structure has a normal storage capacity of 9.5 acre-feet and a maximum storage of 14 acre-feet.
This significant facility covers a surface area of 2 acres and plays a vital role in water quality management and environmental protection in the region. The dam, primarily designed for sewage treatment purposes, is in fair condition as of the last inspection in September 2021 and is subject to regular inspections to ensure its continued functionality and safety. With a hazard potential deemed significant, the lagoon is equipped to handle emergencies and has protocols in place for risk management and mitigation.
Fairfield Sewage Aerated Lagoon - Lagoon 1, while not a traditional dam, represents a critical infrastructure for water treatment and management in the area. As part of a comprehensive sewage treatment system, this facility contributes to maintaining water quality standards and protecting the environment. With a focus on regulatory compliance and operational effectiveness, this lagoon stands as a testament to the importance of sustainable water resource management and climate resilience efforts 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.
- 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.
- 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.
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, environmental 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.

About Fairfield Sewage Aerated Lagoon - Lagoon 1
Where does the data for Fairfield Sewage Aerated Lagoon - Lagoon 1 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
