You can help reduce road flooding by keeping drains clear of leaves and debris and reporting problems to Surface Water Management (SWM). For emergencies and urgent problems outside of normal business hours, please call 911.
When the rains fall, check if your route has been impacted. Information about county road closures can be found online. To report issues to county road staff, call 425-388-ROAD (7626) or email road@snoco.org. SWM also provides up-to-date information about river conditions. The Flood Information Center serves as a “one-stop” source for real-time river level and rainfall depth data in Snohomish County.
Algae blooms can appear in our local lakes, especially in the fall. Some blooms have the potential to be toxic to lake users and pets. Algae blooms can look like blue or green scum on the lake surface or large clumps in the water. If found, please exercise caution and report the bloom to SWM. Once reported, the lake boat launch will be posted with a sign alerting users to the risk. Visit our Toxic Algae web page to learn more and to see current toxic algae alerts.
Thanks to King5 for sharing what steps to take if you own or see a boat in disrepair. Use the MyCoast app to report abandoned boats or other large marine debris. If you have an old boat, please work with the Washington Department of Natural Resources (DNR) Vessel Turn in Program to guide how to safely dispose of your boat.

Snohomish County has approximately 4,000 culverts that cross under county roads. Since 2016, SWM staff have inventoried and evaluated over 3,200 of them and have rated 540 as problem culverts, either as a barrier to fish passage or in poor enough condition that a replacement is soon warranted. Inspections help the county plan future capital investments.
 A large culvert buried partially in the streambed with gravel in the bottom better mimics the natural stream and slows the water to help fish swim through the culvert.
Young salmon need healthy estuaries (the area where freshwater meets saltwater) to grow stronger before traveling to the ocean. Construction began last month to restore tidal waters to 74 acres on Mid-Spencer Island, adjacent to Smith Island in Everett. This project helps the county meet salmon restoration goals. Read more about countywide estuary restoration efforts in this Daily Herald article.
