Early in the afternoon of Wednesday, September 4, a fire was reported burning south of the Flournoy Bridge in Genesee Valley. First responders estimated the size of the fire to be roughly between 3 and 5 acres, however, burning with a critical rate of spread due to strong and erratic winds. By late evening of that day, the fire was over 750 acres in size as the community of Genesee Valley was placed under a mandatory evacuation order. On Thursday, September 5, firefighters were reportedly making good progress as the fire was at 5% containment with 850 acres burned. However, later in the day, downdraft winds from late afternoon thunderstorms caused spotting ahead of the fireline which expanded the burn area to encompass up to. By Friday, September 6, fire activity had picked up significantly as further erratic, unpredictable winds and dry conditions lead the advancing fireline further out of Plumas National Forest towards the northeast spurring new voluntary evacuations of structures below Forest Road 26N11. The fire, originally burning Friday morning, had exploded to well over acres by Friday night due to the severe weather conditions, sending up a massive smoke column that was reportedly seen from as far as Reno. The fire was then over acres in size by Saturday morning as containment remained at 0%. On September 10, the Walker Fire had grown to and was 12 percent contained. The Lassen County Fairground evacuation center was closed that morning. The majority of residential evacuation orders were lifted, except the Murdock Crossing and Stoney areas. The next evening, the fire continued to grow, but was 28 percent contained. Crews extended dozer lines and handlines to expand the containment. Structural defense was put in place for buildings at Murdock Crossing and mop up continued at Antelope Lake, Round Mountain and the eastern side of the fire. However, by the morning ofSeptember 14, the fire had expanded to and was 97 percent contained.
