Weather helps firefighters slow Mendocino Complex growth

LAKE COUNTY, Calif. – Better weather conditions and strengthening containment lines on the Mendocino Complex allowed more Lake County residents to return home on Tuesday after a lengthy evacuation.
Cal Fire said the growth on the complex, burning since July 27, was held to approximately 2,000 acres during the day on Tuesday, rising to 292,692 acres. Containment remained flat at 34 percent.
All of that new growth occurred on the Ranch fire, up to 243,772 acres and 20-percent containment, while the River fire’s size and containment, 48,920 acres and 78-percent containment, respectively, did not change, according to Cal Fire.
Also showing no change so far are damage assessment numbers: 143 structures destroyed and 26 damaged. Approximately 10,300 structures remain threatened.
Cal Fire said weather played a big factor on Tuesday. The winds aloft covered the fire area in smoke, causing lower-than-predicted temperatures that allowed crews to continue critical work to contain the fire perimeter edge, thus slowing growth.
Those winds also caused visibility issues for aircraft early Tuesday evening. When visibility dropped to less than a mile at around 6 p.m., all aircraft – including helicopters – were called off the complex for the night, according to incident radio traffic.
Cal Fire said the River fire continued to be cleaned up on Tuesday, and it’s progressing steadily toward full containment.
Conditions on the Ranch fire remained dynamic on Tuesday, with a flare up requiring a mandatory evacuation order in Mendocino County south of the Eel River, west of the Mendocino-Lake County line, east of the 10500 block of Mid Mountain Road and north of Pine Avenue. At that time Cal Fire also stated that “houses on Pine avenue are not affected.”
In Lake County, the situation improved enough that on Tuesday morning the mandatory evacuation order was lifted for Blue Lakes, Bachelor Valley, Witter Springs, Saratoga Springs and Scotts Valley, with the advisory evacuation for those areas lifted during the afternoon.
The area from Upper Lake to Clearlake Oaks remains under mandatory evacuation as firefighters continue to strengthen containment lines along the Northshore.
A mandatory evacuation also remains in effect in Colusa County for the area south of the Glenn-Colusa County line, north of Highway 20 and west of Bear Valley, Leesville Lodoga Road, Sites Lodoga Road and County Road 401.
Mapping showed the Ranch fire has continued to push north farther into Colusa County, reaching the outskirts of Lodoga by Tuesday night.
In Glenn County, an advisory evacuation is in place for the area north of the Glenn County/Colusa County line, west of County Road 306, south of County Road 308, east of the Mendocino National Forest boundary.
By Tuesday night, the Ranch fire hadn’t yet passed into Glenn County’s boundaries; at about 9 p.m. fire mapping showed the fire to be about 5 miles south of the Colusa-Glenn County line. However, a tweet posted from the Glenn County Office of Emergency Services Twitter account after 8 p.m. Tuesday said that a potential threat remains to southwestern Glenn County.
The goal Tuesday night is to use the lower temperatures to increase the incident’s containment lines, Cal Fire said.
With the complex still burning actively and growing, Cal Fire on Tuesday pushed back the estimated date of full containment by two weeks to Sept. 1.
Cal Fire said the resources assigned include 4,088 firefighting personnel, 381 engines, 96 water tenders, 19 helicopters, 63 hand crews and 89 dozers.
In other fire-related news on Tuesday, the Board of Supervisors unanimously approved a proclamation of a local health emergency due to the Mendocino Complex, formally requested from Dr. Gary Pace, Lake County’s interim health officer, and received brief updates from county staff about their response to the incident.
In addition to firefighters, the response to the complex includes a large force of workers from Pacific Gas and Electric Co., which has established a base camp at the Lake County Fairgrounds in Lakeport.
PG&E spokeswoman Deanna Contreras said there are 800 employees working out of the camp, from crews to mutual aid, contractors and other personnel.
On Tuesday night Contreras said PG&E is working to restore power safely and as quickly as possible in the fire-impacted areas. At that point, she said there were fewer than 300 customers without power, all of them in Blue Lakes and Clearlake Oaks.
“Today, we have made a significant amount of repairs to areas where we have access, however, there are still some areas where the fire is actively burning. Therefore we are at about 90 percent in assessing all of our equipment,” she said.
The company pretreated more than 800 wooden poles with fire suppressant that were in the fire’s path to minimize damage, she said.
Throughout the entire complex, at least 264 poles and eight transformers need to be replaced. Contreras said 25 of those damaged wooden poles have already been replaced with steel poles, and PG&E is continuing to determine locations for other steel poles.
Cal Fire said it will hold a virtual meeting to update the community on the latest developments on the complex at 6 p.m. Wednesday. The meeting can be viewed on the Cal Fire Mendocino Unit Facebook page, the county of Lake’s Facebook page and PEG TV Channel 8, or listened to live on KPFZ 88.1 FM.
