Firefighters on the Dixie Fire south of Chester, California had a better opportunity than they have seen recently to make progress on the blaze that has burned 197,000 acres. Dense smoke and occasional clouds shaded the area Sunday which put a damper on fire activity. The decreased intensity allowed crews to move closer to the fire’s edge to construct dozer and hand lines in some key areas including near Taylorsville, Crescent Mills, Quincy, Bucks Lake, and Greenville.

Similar weather conditions are expected Monday, but if the smoke clears there will be a significant increase in fire behavior. The forecast includes 20-30% chance of thunderstorms Monday night and Tuesday, which will be followed by increased winds and higher temperatures later this week.

Engines are deployed in Taylorsville, prepping for structure protection in the event the fire reaches the area as it continues moving northeast. Sunday night firefighters began strategic firing operations using the Mount Hough Road to strengthen the fireline north of Quincy.

Poor visibility created by the smoke limited assistance fire personnel could receive from air tankers and helicopters but drones are being to gather intelligence, monitor fire activity at night, watch for spot fires, and assist in igniting tactical burning operations.

With the inability to drop fire retardant from air tankers, on Sunday water tenders filled with the slurry pretreated areas along Humbolt Road and other locations where burning operations took place. The retardant was sprayed on the opposite side of roads from where the ignitions were occurring. Firefighters always have to be cognizant of burning embers being blown across a road in a firing operation, but the report Monday morning was that no spot fires occurred Sunday night on the project where the retardant was used. Most of the tactical firing is occurring at night when weather and fuel conditions are more moderate than in the daylight hours. Air tankers can’t be used at night to drop retardant but water tenders can be operated 24 hours a day.

The fire is extremely large, reaching “megafire” status a number of days ago when it exceeded 100,000 acres. Now it is almost twice as big, with three base camps, and has an outer perimeter of 82 miles all of which has to be secured by firefighters.

Saturday night the Dixie Fire south of Lake Almanor in Northern California merged with the Fly Fire near Highway 89 and the communities of Indian Wells and Paxton. At that time the Fly Fire was approximately 8,000 acres. With the additional growth over the last 24 hours it brings the combined size up to 190,625 acres.

The fire grew significantly Saturday in conditions that were very challenging for firefighters. The Fly Fire spread to the top of Mt. Hough and Crystal Lake and is now expected to back down the mountain to the northeast.

Saturday the east side of the fire burned into the Greenville Wye and across Highways 70 and 89. Firefighters engaged immediately in structure protection in nearby communities, with Paxton and Indian Falls being the most severely impacted. Several strike teams of engines were in the area fighting to protect structures as the fire intensified.

Extreme fire behavior is expected again Sunday, with unstable atmospheric conditions predicted that could lead to the development of large pyrocumulonimbus clouds, increasing the potential for spot fires and rapid fire growth.

This very large fire is being suppressed by two Incident Management Teams, with their areas of responsibility separated by the Highway 70 corridor.

Due to a massive smoke plume the street lights came on Saturday at 4:51 p.m. in Greenville, California, which at the time was about three miles northeast of the fire.

The burning operation underway south of Lake Almanor is going well. Crews started from Canyondam working west and are circling around the north and northwest sides of the fire working toward Butte Meadows. As of early Sunday morning crews had progressed approximately 12 miles from Canyondam, burning the fuels along a road system to create a barrier to the main fire to protect the Lake Almanor area. The objective is to tie in the burning operation with crews constructing direct fire line on the southwest side of the fire.

The prescription for the firing calls for it to be done at night, conditions that make it easier for firefighters to control the fire intensity. The ignition and prescription are similar to conducting a prescribed fire. The project can be seen on the map above, appearing as a strip of white lines south of Highway 89, with red dots signifying heat from their burning operation.

The AlertWildfire camera on Indian Ridge photographed the Fly Fire Saturday afternoon as it spread vigorously toward its location. The camera is north of the community of Keddie and northwest of Mt. Hough and Crystal Lake.

These first four pictures were shot during a five-minute period, 2:22 p.m. to 2:26 p.m. on July 24, 2021.

Judging from the photo below taken from the same camera almost two hours later at 4:10 p.m., the camera survived but the lens needs a little cleaning.

The Fly Fire was reported Thursday, July 22 near Keddie in Butterfly Valley about four miles north of Quincy. At first there was a question whether it was a spot fire from the Dixie Fire several miles away, or if it was unrelated. A fire behavior analysis determined the spot fire option was unlikely, but at times this year the behaviors of wildfires are off the charts. Regardless, the cause is being investigated and it is being suppressed by the Dixie Fire Incident Management Team. As of early Saturday morning it had burned more than 4,000 acres.

The Dixie Fire, six air miles south of Chester, California, was very active Friday, but not as much as on Thursday due to a decrease in wind speeds. While it still created convection columns of smoke topped by white pyrocumulus clouds, they were not as large and the fire did not increase in size as much as in previous days, but it still grew by tens of thousands of acres, expanding to 181,289 acres by Saturday morning.

The east side near Caribou, Twain, and Paxton, as well as the nearby Fly Fire at Kiddie, spread one to two miles further east. The Fly Fire is a new fire that started Thursday.

Wednesday night firefighters began a firing operation north of the fire to create a burned area south of Lake Almanor intended to stop the northward progress of the fire. They are working from a road system south of and parallel with Highway 89, starting from Canyondam working west and then plan to circle around the northwest side of the fire toward Butte Meadows. The prescription for the firing calls for it to be done at night, conditions that make it easier for firefighters to control the fire intensity. This is similar to conducting a prescribed fire. By early Saturday morning crews had initiated firing along approximately nine miles of roads, working toward the west-northwest. The project can be seen on the map above, appearing as a strip of white lines south of Highway 89.

The fire has been split into two zones organizationally, East and West, each with its own Incident Management Team.

The weather forecast for Saturday calls for warmer and drier conditions with relative humidities in the upper single digits and temperatures ranging from 80 to 100 degrees depending on the elevation. Wind speeds will be in the 10 to 15 mph range. The very low humidity, high temperatures, and wind, combined with the very low fuel moistures will present difficult conditions for firefighters.

Calmer winds Friday allowed firefighters on the 65,152-acre Tamarack Fire 14 miles southeast of South Lake Tahoe to make progress, especially on the north and northeast sides of the fire. On Saturday they are expecting similar conditions which should allow additional containment efforts.

The Incident Management Team recorded a very informative video Saturday morning, featuring Operations Section Chief Pat Seekins.

On Thursday the Tamarack Fire, pushed by strong winds, spread east across US Highway 395 in spite of firefighters’ best efforts to stop it at the highway with a burning operation. Within a few hours it burned about 2,500 acres east of the highway, becoming well established on that side.

On Tuesday the fire burned from California into Nevada. A mapping flight at 7:25 p.m. Thursday determined it had grown by about 7,000 acres to a total of 58,417 acres.

It crossed 395 a mile or two north of Holbrook Junction, which is the intersection with Highway 208. Friday afternoon the FlightRadar24 service showed a great deal of air tanker activity southeast of the junction. That would indicate that the fire had spread into the area between 208 and Topaz Lake, but it remains to be confirmed.

There are 1,353 personnel working on the fire and more resources are on order. Firefighting operations continue around the clock, with additional crews added to the night shift. Night operations include structure protection and firing operations when conditions are suitable.

Firefighters have continued to keep the fire south of Highway 88, which with Highway 89 were both closed in the fire area Friday morning to all traffic except incident personnel. A portion of 395 was also closed Friday morning for firefighter and public safety.

On Thursday an additional 1,369 people were evacuated primarily from the Hwy 395 corridor, bringing the total number of those evacuated to 2,439.

The Incident Management Team has created an interactive map that is intended to have evacuation information for residents.

On Tuesday the Tamarack Fire burned from California into Nevada, and Thursday afternoon it made another big push to the east and hit US Highway 395 with some intensity north of Holbrook Junction. At first it was just a spot fire across the road but it grew very rapidly and at 4:10 p.m. aerial firefighters estimated it had burned 2,500 acres east of the highway.

Several large air tankers including a DC-10 Very Large Air Tanker assisted firefighters on the ground in an attempt to stop the spread of slopover across the highway.

The Incident Management Team that is suppressing the Tamarack Fire posted on InciWeb their view about how the fire was managed during the first 12 days after it started. The statement was presumably approved by the U.S. Forest Service, the jurisdiction responsible for suppressing and/or managing the fire which was on the Humboldt-Toiyabe National Forest.

“The Tamarack Fire on the Humboldt-Toiyabe National Forest was discovered on July 4,” the statement says. “At the time, 23 other lightning fires were burning.  It was a single tree burning in the Mokelumne Wilderness on a rocky ridgetop with sparse fuels and natural barriers to contain it. The steep, rugged, and remote terrain presented challenges to safely suppress this wilderness fire.  With several higher priority fires in the area and due to the remote location, the sparse fuels and natural barriers, and the concern for firefighter safety, the decision was made to monitor the Tamarack Fire.”

“The Tamarack Fire was monitored daily via air and fire cameras and exhibited very little fire behavior until Friday, July 16 when fueled by extreme winds and low humidity, it progressed rapidly downslope and spread throughout the evening. With this rapid change in the fire, fire resources were dispatched on Friday, July 16. Additional firefighting resources were also ordered, including very Large Air Tankers (VLAT), Single Engine Airtankers (SEATS) and helicopters.”

Below is a still image of a Forest Service Facebook post with a video of the fire when it was a quarter acre on July 10, six days after it started. “Fire poses no threat to the public, infrastructure, or resource values,” they wrote.

The Tamarack Fire spread further east on Tuesday, crossing the state line from California into Nevada. From its origin, it has now spread 15 miles northeast and 10 miles to the north, burning 10 structures and approximately 40,000 acres.
