Springwood Stormwater Detention Dam dam
Springwood Stormwater Detention Dam
Springwood Stormwater Detention Dam, located in Kent, Washington, serves as a vital tool for flood risk reduction in the area. Completed in 1992, this earth dam with a hydraulic height of 10 feet and a storage capacity of 50 acre-feet plays a crucial role in managing stormwater runoff from Soos Creek and Wetland 87. With a surface area of 7 acres and a drainage area of 0.69 square miles, this dam helps protect the community from potential flooding events, making it a key infrastructure for water resource management in the region.
Owned and regulated by the local government, specifically the Washington Department of Ecology, Springwood Stormwater Detention Dam undergoes regular inspections to ensure its structural integrity and functionality. Despite its high hazard potential, the dam is currently assessed to be in fair condition as of the last inspection in September 2017. The dam's emergency action plan and risk management measures are important aspects of its operation, although specific details on these aspects are currently not available. With its primary purpose being flood risk reduction, this dam serves as a critical piece of infrastructure to safeguard the surrounding community from the impacts of extreme weather events.
As part of the broader water resource management efforts in King County, Washington, Springwood Stormwater Detention Dam plays a significant role in regulating water flow and protecting downstream areas from potential inundation. With a solid foundation on soil and a core made of stone, this dam stands as a testament to engineering ingenuity in managing water resources effectively. Its location along Soos Creek and Wetland 87 underscores its importance in preserving the local ecosystem while mitigating flood risks for nearby residents.

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 Springwood Stormwater Detention Dam
Where does the data for Springwood Stormwater Detention 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.
