Carnation Waste Pond No 7 dam
Carnation Waste Pond No 7
Carnation Waste Pond No 7 is a privately owned offstream water storage structure located in Grant County, Washington. Constructed in 1979, this Earth-type dam stands at a hydraulic height of 16 feet with a structural height of 12 feet and a length of 1930 feet. It has a normal storage capacity of 71 acre-feet and a maximum storage of 99 acre-feet, serving as a critical resource for the area's water supply and management.
Managed by the Washington Department of Ecology, Carnation Waste Pond No 7 is subject to state regulation, inspection, and enforcement to ensure its safety and compliance with environmental standards. With a low hazard potential and a condition assessment of "Not Rated," this dam plays a vital role in water resource management in the region. While lacking detailed information on emergency preparedness and risk assessment, its purpose and design highlight the importance of sustainable water infrastructure for both human and environmental well-being.
As part of the Seattle District's water management system, Carnation Waste Pond No 7 contributes to the overall water quality and availability in the area. With its stone core and rock and soil foundations, this structure exemplifies the intersection of engineering and environmental stewardship in maintaining a balance between human needs and ecological sustainability. For water resource and climate enthusiasts, understanding the intricacies of such water management infrastructure sheds light on the complexities and challenges of ensuring a resilient and sustainable water future.

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 Carnation Waste Pond No 7
Where does the data for Carnation Waste Pond No 7 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.
