Teal Duck Slough Dam dam
Teal Duck Slough Dam
Teal Duck Slough Dam, located in Tokeland, Washington, is a vital structure owned by the Tribal Government. This dam serves primarily for recreational purposes and stands as an earth-type dam with stone core. Completed in 1960, the dam has a hydraulic height of 8 feet and a structural height of 6 feet, spanning 500 feet in length. It has a storage capacity of 50 acre-feet, with a normal storage of 10 acre-feet, covering a surface area of 5 acres and serving a drainage area of 0.7 square miles.
Managed by the Washington Department of Ecology, the Teal Duck Slough Dam is regulated and inspected by the state to ensure its safety and compliance with standards. Despite being rated as low hazard potential and not having a current condition assessment, the dam continues to be an essential part of the local ecosystem and recreational activities. With its location near the Tr-Pacific Ocean, the dam plays a crucial role in water resource management and environmental conservation efforts in the Pacific County of Washington.
With its historical significance and continued importance in the region, the Teal Duck Slough Dam exemplifies the intersection of water resource management and climate resilience. As enthusiasts and researchers explore its design and impact, the dam serves as a reminder of the delicate balance between human development and environmental stewardship in the face of changing climate patterns.
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 Teal Duck Slough Dam
Where does the data for Teal Duck Slough Dam 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.
