A brush fire that kicked up in the Whittier Narrows riverbed on Sunday was boxed in quickly by Los Angeles County Fire crews, who stopped its forward progress at roughly 8 to 10 acres and then spent the afternoon chasing down hot spots.
The blaze was reported midday in the wash at Whittier Narrows Recreation Area and pulled in engines and hand crews into the river channel. Firefighters focused on knocking down the main body of fire, then transitioned to mop up while investigators kept an eye on conditions.
According to the L.A. County Fire Department, units responded near North Rosemead Boulevard and North San Gabriel Boulevard, where the incident was designated FS90. Crews stopped forward progress at 8 to 10 acres at 1:29 p.m., then worked the perimeter to prevent any rekindling in the brushy riverbed.

Where the blaze burned
The County of Los Angeles Department of Parks and Recreation describes Whittier Narrows as a large county recreation area that includes riverbed habitat, lakes and the Whittier Narrows Nature Center at 1000 N. Durfee Avenue. The river channel threading between the San Gabriel and Rio Hondo rivers is narrow and choked with brush and willows, a layout that makes it tough for heavy firefighting vehicles to maneuver in the wash and helps explain why a fast, precise response is often needed there.
Background
Fires have flared in this river corridor before. In 2019, a blaze in the same general stretch was held to only a few acres after a rapid county response, a reminder of how quickly riverbed fires can grow if they are not hit early. The Los Angeles Times reported that during that Durfee fire, crews used engines, hand lines and aircraft to limit the footprint and protect nearby communities and park facilities.
What residents should know
Residents and park visitors are encouraged to keep an eye on official updates for any changes to park access or air quality guidance. The County of Los Angeles Department of Parks and Recreation provides current park information and alerts.
If you spot smoke in or around the Whittier Narrows area, report it to local emergency dispatch so firefighters can pin down the location quickly and get crews into the wash before a small flare up turns into a larger riverbed problem.
