Snohomish County's Surface Water Management Division provides a variety of programs and services for reducing road and property flooding and preserving and improving the health of Snohomish County's water resources and natural systems. We focus on four areas of service:
Clean water in rivers, streams and lakes;
Habitat for fish and aquatic wildlife;
River flooding and erosion;
Stormwater drainage systems.
We work in partnership with the residents of Snohomish County. You can find us responding to water-quality problems and complaints, monitoring river levels during flood season, maintaining drainage systems, managing habitat improvement projects and more.

Noxious weeds such as white or pink waterlillies are invasive plants that can harm lakes and impede recreation.
