George City Wastewater Treatment Lagoon dam
George City Wastewater Treatment Lagoon
The George City Wastewater Treatment Lagoon in Grant County, Washington is a crucial offstream facility designed by EMCON in 1996 for the local government. This Earth-type dam stands at a height of 9 feet and spans 3060 feet in length, with a storage capacity of 80 acre-feet, serving its primary purpose as a wastewater treatment lagoon. Situated on the Columbia River watershed, this low-hazard structure ensures proper water management for the region.
Maintained and regulated by the Washington Department of Ecology, the George City Wastewater Treatment Lagoon plays a vital role in ensuring water quality and environmental protection in the area. With a normal storage capacity of 66 acre-feet and a maximum discharge rate of 1.5 cubic feet per second, this facility aids in managing drainage and wastewater while minimizing the risk of inundation and water contamination. The lagoon covers a surface area of 6.6 acres and serves as an essential infrastructure for water resource management in the region.
Owned by the local government and located in Congressional District 04, Washington, the George City Wastewater Treatment Lagoon exemplifies sustainable water resource management practices. With state-regulated inspections and enforcement mechanisms in place, this lagoon stands as a testament to responsible infrastructure development and environmental stewardship in the face of climate challenges and water scarcity concerns.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About George City Wastewater Treatment Lagoon
Where does the data for George City Wastewater Treatment Lagoon 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 Low 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.
