Fireworks have heavy metals, perchlorate and other pollutants that can harm people and the environment. The chemicals in fireworks can pollute our rivers, lakes, and streams when fireworks are detonated over waterbodies and when firework waste is not disposed of properly. See our list of good housekeeping tips for this Fourth of July holiday.
Visit the Snohomish County Fire Marshall’s webpage for information on where it is legal and illegal to discharge fireworks and tips to keep safe. If you have questions or would like to report a water pollution concern, please call the Water Quality Complaint Hotline at 425-388-6481 or use the on-line water pollution reporting system.
 Help us keep local waterways healthy by practicing good firework housekeeping.
Recent surveys by SWM’s State of Our Waters (SOW) monitoring team detected a highly invasive species, the New Zealand mud snail, in several local creeks in north Snohomish County near Stanwood:
- Hulbert Creek
- Jorgenson Slough
- Freedom Creek
- Douglas Creek
These tiny creatures – only 1/8 inch long – can hide on plants, watercraft, debris, boots, shoes, nets, and more. Once established, New Zealand mud snails are extremely difficult to control, and threaten food sources for salmon, steelhead and trout. You can help stop the spread of these aquatic hitchhikers and other harmful invasive species. Be sure you CLEAN, DRAIN and DRY your boat, kayak, and all gear before leaving a body of water. Learn more at https://snohomishcountywa.gov/invasives.
 Look for signs like these at boat launches, trail crossings and other access points to help stop the spread of invasive species.
On July 1, Snohomish County was awarded our fourth Floodplains by Design (FbD) grant for SWM’s Community Floodplains Solutions (CFS) Program totaling $10M. Grant benefits include:
-
Increasing functional habitat and floodplain connections while reducing flooding impacts to local infrastructure: $1.1 million supports the Chinook Marsh project, reconnecting more than 400 acres of floodplain habitat while protecting critical infrastructure like the City of Everett water line.
-
Protecting and enhancing farmland productivity: $1 million supports the Office of Agriculture’s Ag Tech Program (see article below), bringing leading-edge technology and data driven insights to local farmers at no cost.
-
Strengthening community through collaboration: Nearly $4.5 million will be passed through to grant partners to advance important floodplain projects, including the Tulalip Tribes, Snohomish Conservation District, Washington Farmland Trust, Ducks Unlimited, and Adopt A Stream Foundation. The remaining $3.3 million will support the CFS program and projects that Snohomish County is implementing.

The Snohomish County Ag Tech Program brings leading-edge technology and data-driven insights to farmers at no cost to the producer. Farmers can borrow available technologies to enhance productivity, optimize resource use, and promote sustainable agricultural practices, ensuring regional food security. By using only what farmer’s crops need, farmers can reduce their use of water, fertilizer and other inputs. This project was made possible by funding from Washington State’s Department of Ecology Floodplains By Design grant program.
Due to the funding sources of this program, it is currently only available to commercial farmers in the Snohomish watershed.

We prepare the Stormwater Management Program (SWMP) Plan annually. The 2025 SWMP Plan describes the activities and programs the county will carry out to meet the requirements of the stormwater permit for the calendar year. If you would like to provide comments on the actions and programs described in the SWMP Plan please email us at: [email protected]
Snohomish County prepares the annual SWMP Plan to comply with federal clean water laws outlined in the National Pollution Discharge Elimination System (NPDES) Permit.
