Beaches, Lakes, Rivers

The Snohomish Health District protects the environment and water quality of the county’s lakes, rivers, and the Puget Sound waterfront by:

  • Regulating septic systems and solid waste
  • Reducing hazardous waste in homes and businesses
  • Supporting community efforts to prevent pollution

If you are concerned about an immediate water pollution problem that might be a threat to you or the environment, please call 911. For other pollution concerns, contact the Snohomish County Surface Water Management.

Lake and beach water quality

The water at swimming beaches is not treated, and the Snohomish Health District does not regulate lake and river water quality. Local sanitary codes require public beaches to provide information on how to prevent illness. The water quality in many local lakes is monitored by the Snohomish County Surface Water Management with the help of community volunteers. 

For updates on Snohomish County water quality, residents should use the following resources:
