Stormwater Overview:

The Lynden Public Works Department is responsible for providing environmentally sound, efficient and effective management of the City’s storm drainage system; which includes catch basins, curbs, gutters, ditches, man-made channels, pipes, tunnels, and storm drains. Most of what comes into our storm drains goes straight into Fishtrap Creek and ultimately into the Nooksack River; which are both considered waters of the United States. The City of Lynden’s Stormwater Program includes the following elements:

  • Public Education and Outreach
  • Public Involvement and Participation
  • Illicit Discharge Detection and Elimination
  • Control of Runoff from New Development, Redevelopment and Construction Sites
  • Pollution Prevention, and Operation and Maintenance for Municipal Operations
  • Water Quality Monitoring

Additionally, the Stormwater Program provides for investigation and resolution of drainage complaints and flood management. To preserve the health of our local streams, creeks and rivers, report any water pollution by calling our Public Works Stormwater Hotline at:

  • (360) 354-3446 during work hours (8 am to 5 pm)
  • (360) 815-5755 outside of normal working hours

For hazardous material spills call 911 and dispatchers will immediately contact the appropriate agencies. What materials and activities are harmful to our waterways? Following, are some activities that can allow polluted water to flow into a storm drain or water body:

  • Car Washing (dirt, road grime, oil, nutrient and heavy metals, along with detergent-rich water used to wash the dirt off our cars flows down the street, into the storm drain and into Fishtrap Creek.
  • Pressure washing
  • Carpet cleaning
  • Paint chipping, sanding or pressure washing
  • Cleaning of painting materials
  • Hazardous material spills
  • Over watering a lawn, allowing water to flow into the street and storm drain
  • Car leaks
  • Pet Waste (not properly cleaning it up!)
  • Improper storage of oil, pesticides, dirt, fertilizer, and other materials
  • Erosion of dirt or landscaping materials to a storm drain or water body
  • Dumping grass or other yard waste on public property or right of ways
  • Over use of fertilizers
  • Storm drains that are not working properly

You can protect our waterways by:

  • Using commercial car-wash facilities. They are required to recycle and treat their wash water prior to discharging it to the sanitary sewer system.  In the sewer system, the water is treated at the wastewater treatment plant before it is ultimately discharged to the Nooksack River.
  • When washing vehicles at home, a sump pump can be placed in the storm drain where the wash water flows. The pump should pump the wash water through a hose to the sanitary sewer.
  • Another alternative is to wash the car on a pervious surface such as a lawn or vegetated area so the wash water can soak into the ground, where pollutants are filtered out.
