The December 2025 flood and the river
At Carnation the Snoqualmie River crested at 60.76 feet on December 11, 2025, making it the valley's worst flood since January 2009. A Duvall farmer said high king tides backing up the river combined with the atmospheric river to flood Duvall.
King County runs a flood warning gauge on the river at Duvall, and all major routes into town cross the floodplain, so cleanup often waits for access to reopen.

Runoff, drainage and heavy rain
Not every flood comes from the river. The city plan describes limited stormwater infrastructure and aging culverts, so a downpour on the hillside can send water through garages and into lower levels.
Small garage and runoff jobs follow water extraction steps, and cleanup adds antimicrobial treatment.
Drying after the cleanup
Once contaminated materials are out and surfaces are sanitized, dehumidifiers and air movers dry the rest, and sewage backup cleanup handles any drain backup that came with the storm.
Trade fact: Flood water that touches porous materials such as drywall and pad is treated as contaminated, so those items are removed even if they look clean.

Related water damage services in Duvall
Is river flood water considered contaminated?
Yes. It carries soil, bacteria and debris, so porous materials are removed and hard surfaces are cleaned and sanitized.
Can flooding cut Duvall off from the roads?
Yes. Every major route crosses the river floodplain, and flooding can close land routes for days, which can delay a cleanup.
Does flood damage fall under homeowners insurance?
Rising river water is usually excluded from a standard homeowner policy and handled by separate flood coverage, so the carrier should confirm.
What gets thrown away after a flood?
Carpet, pad, soaked drywall and insulation that touched the water are usually discarded, while hard surfaces are cleaned.
How is runoff different from river flooding?
Runoff comes from heavy rain over the hillside and drains, and it can carry soil, but river water usually brings more contamination.
How is the structure confirmed dry?
Moisture readings are compared with a dry reference, and equipment stays until the framing and subfloor match it.
Clean up the flood water before it settles in
The crew extracts the water, removes what cannot be cleaned, sanitizes and dries with readings saved for the claim.
