Over 50 Firefighters Respond to Fast-Moving Wildfire North of Rigby, Idaho
RIGBY — A fast-moving wildfire broke out Thursday afternoon just north of Rigby, Idaho, along the bank of the Snake River, prompting a multi-agency response and calls for nearby residents to prepare for possible evacuation. The Snake Fire, which had grown to approximately 10 acres as of Thursday evening, drew more than 50 firefighters from agencies across eastern Idaho working to bring the blaze under control.
According to WatchDuty, a wildfire mapping application, the fire ignited at approximately 3:45 p.m. near East 550 North and North 4200 East. Central Fire Chief Nic White, who was on scene, confirmed to reporters that the cause of the fire was a controlled burn that escaped containment. The blaze spread rapidly along the Snake River corridor, prompting an urgent response from local, county, and federal agencies.
Chief White confirmed the fire originated on the south side of the Snake River but had jumped the river by Thursday evening, requiring crews to work on both banks simultaneously to halt its spread. Madison County marine deputies were also deployed, assisting Jefferson and Madison County firefighters by providing boat transportation to fire locations along the river — an indication of how the waterway both complicated and shaped the firefighting effort.
Evacuation Preparations Ordered for Residents West of Big Juds Along the River
Fire officials issued preparation-to-evacuate notices for residents south of West 6800 South, 7800 South, and 8200 South, and west of 400 West on those roads — areas described as homes west of Big Juds and along the river. Sheriff’s deputies were going door to door to notify residents as the fire moved through the area.
Authorities urged residents to obey all evacuation orders and to avoid the area entirely due to the fire’s fast-moving nature. Officials directed the public to check warn.pbs.org for the most up-to-date information on fire conditions, boundaries, and evacuation notices.
The multi-agency response included Central Fire, Robert Fire Department, Idaho Falls Fire Department, North Fremont Fire District, Swan Valley Fire District, the Bureau of Land Management, and Bonneville County Fire District 1. The coordinated deployment of departments from across eastern Idaho underscores the seriousness of the fire and the cooperative approach among regional emergency responders.
What Comes Next
As of Thursday evening, firefighting crews remained actively engaged on both sides of the Snake River, working to establish containment lines around the 10-acre blaze. No structures were confirmed destroyed at the time of initial reporting, and no injuries had been publicly reported. Officials had not yet announced a containment percentage or a projected timeline for full control of the fire.
Residents in the affected evacuation preparation zones are urged to remain ready to leave at a moment’s notice and to monitor warn.pbs.org for updated evacuation notices. The Jefferson County area, including communities in the Rigby vicinity, remains on alert as fire crews continue suppression efforts under potentially challenging wind and terrain conditions along the Snake River corridor.
The Snake Fire comes as parts of eastern Idaho enter a period of elevated wildfire risk with spring conditions. Bonneville County and Jefferson County emergency managers are expected to provide additional public updates as the situation develops. Residents with questions or concerns are encouraged to heed all official guidance from on-scene fire commanders and law enforcement.
