Weyerhaeuser Enumclaw Flood Control Dam dam
Weyerhaeuser Enumclaw Flood Control Dam
The Weyerhaeuser Enumclaw Flood Control Dam, located in Enumclaw, Washington, serves as a vital structure for flood risk reduction along Boise Creek. Completed in 1993, this private-owned dam stands at a hydraulic height of 30 feet and a structural height of 24 feet, with a capacity to hold 140 acre-feet of water. Despite its modest size with a surface area of 0.1 acres, the dam plays a crucial role in protecting the surrounding area from potential flooding events.
Managed by the Washington Department of Ecology, the Weyerhaeuser Enumclaw Flood Control Dam is state-regulated and regularly inspected to ensure its structural integrity and functionality. With a hazard potential rated as high and a fair condition assessment as of the last inspection in 2015, the dam is equipped to handle maximum discharges of up to 1800 cubic feet per second. Its roller-compacted concrete core and soil foundation contribute to its stability and effectiveness in flood control measures, making it a key asset for water resource and climate enthusiasts in the region.
In the event of an emergency, the dam's emergency action plan (EAP) readiness and adherence to guidelines are critical factors in ensuring public safety. While details on the EAP's preparation and revision dates are currently unavailable, the dam's risk management measures and potential inundation maps are essential components for effective emergency response and risk mitigation. As a significant infrastructure within Congressional District 08 of Washington, the Weyerhaeuser Enumclaw Flood Control Dam highlights the importance of proactive measures in safeguarding communities against the impacts of extreme weather events and climate change.
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 Weyerhaeuser Enumclaw Flood Control Dam
Where does the data for Weyerhaeuser Enumclaw Flood Control 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 High 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.
