Summary
This earth dam, completed in 1996, serves the primary purpose of a Fish and Wildlife Pond, while also contributing to Flood Risk Reduction in the area. Situated on Hylebos Creek, the dam has a hydraulic height of 19 feet and a storage capacity of 49 acre-feet, with a normal storage level of 4.19 feet.
Despite its fair condition assessment as of March 2018, South 336th Street Stormwater Dam No 2 poses a high hazard potential, emphasizing the importance of regular inspections and maintenance. The dam covers a surface area of 2 acres and has a drainage area of 0.59 square miles, with a maximum discharge capacity of 430 cubic feet per second. The structure is regulated by the Washington Department of Ecology, ensuring compliance with state permitting, inspection, and enforcement requirements.
The dam's location within Congressional District 09, Washington, under the representation of Adam Smith (D), further highlights the significance of its role in water resource management and climate resilience. As a crucial component in the local ecosystem, South 336th Street Stormwater Dam No 2 serves as a vital habitat for fish and wildlife, while also playing a key role in mitigating flood risks in the region. Its operational and regulatory framework underscores the collaborative efforts between private ownership and state agencies in safeguarding water resources and enhancing environmental sustainability.

Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
