Sumas flooding on December 11, 2025

WHATCOM COUNTY, Wash. — KIRO 7 is keeping a close eye on the communities impacted by record flooding as Washington is under a state of emergency.

As of 10 p.m. on December 15, here is a look at the evacuations, displacements, and cleanup efforts in Whatcom County, according to Whatcom County Emergency Management:

Impacts

  • There were more than 20 water rescues throughout Everson, Nooksack, and Sumas on Wednesday night, Dec. 10. On Thursday night, Search and Rescue had over 40 calls for rescue.
  • The wastewater treatment plant that serves Everson and Nooksack was shut down during active flooding. Staff are assessing the repair to restore service.
  • The region’s only feed mill, in Sumas, was impacted by flooding up to 6’.

Road Closures

  • Check the County’s road closure list here and check the interactive closure map here.
  • Many roads and bridges have infrastructure damage due to flooding. Those will not be reopened until inspections have determined that they are sound. 
  • Mosquito Lake Road in east county is closed until damage assessment is complete on portions of the roadway that were underwater.

Need to Know

Impacted residents are encouraged to clear out flood debris, if they are able to return home, especially before mold can set in. There are three county debris management sites:

  • 9626 Swanson Rd (intersection of Swanson and Halverstick) 7 a.m. to7 p.m. daily
  • RDS Disposal, 4916 LaBounty Drive, Ferndale, 7:30 a.m. to 5:30 p.m.
  • Republic Services, 1524 Slater Road, Ferndale, 7:30 a.m. to 5:30 p.m.

When dropping off debris, please pre-sort: appliances and hazardous materials must be separated. Some debris cannot be accepted: tires or vehicles, asbestos, machinery or mechanical parts, woody debris, or regular trash.

Damage assessment has begun. To qualify for state or federal funds, it is essential to follow their regulations for reporting damage and to submit those reports through the county DEM. If using other agencies for this process, please ensure DEM (Dept. of Emergency Management) receives your report.
