Quincy Aerated Lagoon No 1 dam
Quincy Aerated Lagoon No 1
Quincy Aerated Lagoon No 1, located in Quincy, Washington, was completed in 1987 with a height of 12 feet and a storage capacity of 10 acre-feet. Managed by the local government, this earth dam structure sits on the Columbia River-Offstream and serves a primary purpose of "Other." With a surface area of 0.9 acres and a drainage area of 0.01 square miles, this lagoon plays a significant role in the region's water resource management.
Despite being classified as having a "Significant" hazard potential, the condition of Quincy Aerated Lagoon No 1 is currently "Not Rated." The dam structure has state regulatory oversight and undergoes regular inspections, with a frequency of every 5 years. While the emergency action plan (EAP) status and risk assessment details are not provided, the lagoon's role in supporting water quality and climate resilience in the area is evident. Water resource and climate enthusiasts can appreciate the importance of this structure in maintaining and enhancing the local ecosystem.
In conclusion, Quincy Aerated Lagoon No 1 stands as a vital component of water infrastructure in Grant County, Washington. Its presence along the Columbia River, coupled with its storage capacity and structural design, showcases the intersection of engineering and environmental stewardship. As efforts continue to monitor and manage this facility, the lagoon remains a key player in ensuring sustainable water resources for the community and safeguarding against potential hazards.
Dam data reference
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 Quincy Aerated Lagoon No 1
Where does the data for Quincy Aerated Lagoon No 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.
