Hog Fire grows to 200 acres, 40 percent contained in Sierra National Forest

Evacuation warnings covered K98 and K99 as the Hog Fire burned along Trimmer Springs Road and Lakeview in the Trimmer area of Sierra National Forest, close to the north shore of Pine Flat Lake. CAL FIRE listed the fire at 200 acres and 40 percent contained in its April 23 update, with the blaze still active and the cause under investigation.

That 40 percent containment figure meant crews had made real progress, but the fire was not under control. Firefighters still had to hold lines around the perimeter, watch for flare-ups in rugged terrain and keep an eye on shifting smoke and wind in the foothills east of Fresno County’s lake country. No civilian injuries, firefighter injuries, civilian deaths, firefighter deaths or structure damage had been reported in that update.

For people living, traveling or recreating near Trimmer, the immediate concern was not just the flames but the ripple effect. Trimmer Springs Road sits in a part of the county where one incident can quickly affect traffic, smoke conditions and access to Pine Flat Lake recreation areas. The Fresno County Sheriff’s Office also issued an evacuation warning for the north shore of Pine Flat Lake, underscoring how quickly the fire threat spread beyond the original ignition area.

By Friday morning, the fire had grown slightly to about 214.8 to 215 acres and had reached 95 percent containment. That marked a major step forward for crews operating under Sierra National Forest unified command, but it still left room for hot spots, mop-up work and monitoring before officials could declare the incident fully secure.

The Hog Fire was small compared with recent major Fresno County wildland fires, but it landed in a county that has not had much margin for error. The 2025 Garnet Fire burned 59,844 acres before it was fully contained, and the 2024 Basin Fire burned 14,023 acres. Those fires showed how fast a foothills ignition can become a regional emergency, especially in a dry season when smoke, evacuation readiness and weekend travel all become part of the same decision for nearby residents.
