Stehekin, Washington: A prolonged flood threat is unfolding across parts of central Washington as rivers continue rising from steady rainfall and accelerated snowmelt. The Stehekin River has moved well beyond flood stage, pushing water across roadways, overtopping temporary crossings, and raising concerns about continued impacts through at least Saturday morning.
By early Tuesday afternoon, the Stehekin River climbed to 21.2 feet, with projections indicating a potential crest near 21.8 feet by Wednesday morning. Flood stage is 19.3 feet, meaning the river has already exceeded critical levels by a significant margin. Water has overtopped the temporary corduroy bridge and is flooding sections of Company Creek Road, while parts of Wood Road are experiencing erosion and structural damage.
Lower Stehekin Valley Facing Extended Impacts
Rainfall totals across Chelan County ranging from 0.25 to 1.25 inches, combined with rapid snowmelt from warmer temperatures, are driving sustained runoff into area rivers. Officials expect the Stehekin River to remain above 20 feet through at least Saturday morning, prolonging road closures and increasing the risk of additional infrastructure damage.
Low-lying areas in the lower Stehekin Valley are especially vulnerable, with saturated ground conditions limiting the ability of waterways to absorb additional runoff. Continued snowmelt at higher elevations could keep river levels elevated even if rainfall tapers off.
Yakima River Near Umtanum Approaching Crest
Flood concerns extend beyond Chelan County. In Kittitas County, the Yakima River near Umtanum is forecast to crest around 35.6 feet Wednesday afternoon, just above flood stage. Minor flooding is anticipated along portions of the river corridor from Teanaway to Ellensburg, including impacts near Irene Rinehart Park.
Further upstream near Easton, the Yakima River is expected to exceed flood stage around midnight Tuesday, with water levels peaking Wednesday before gradually receding Thursday.
Naches River Also Rising
The Naches River near Yakima is also climbing, with projections showing a crest late Wednesday morning. River levels are expected to fall below flood stage by Thursday, but minor flooding could temporarily affect nearby low-lying areas and access roads.
Ongoing Snowmelt Increases Flood Risk
Hydrologists emphasize that this flooding pattern is being driven by a combination of rainfall and accelerated snowmelt. As mountain snowpack continues to melt, waterways may respond quickly to even small additional rain events. That dynamic raises the potential for renewed rises later this week.
With soils already saturated, additional runoff could exacerbate roadway damage, weaken embankments, and slow recovery efforts in affected communities.
Safety Advisory for Residents
Residents in flood-prone areas are urged to:
- Avoid driving through water-covered roads
- Stay clear of fast-moving riverbanks
- Prepare for possible road closures and detours
- Monitor changing river conditions through local alerts
Even shallow water can stall vehicles or hide structural damage beneath the surface. Officials warn that conditions may change rapidly as rivers respond to ongoing runoff.
Outlook Through Saturday
Water levels are expected to gradually decline late in the week, but elevated flows may persist into the weekend. Emergency planners continue monitoring conditions across central Washington, especially in river-adjacent communities.
As snowmelt continues and waterways adjust, residents should remain vigilant and prepared for potential updates or additional flood advisories in the coming days.
