The Mendocino County Board of Supervisors will be holding a special meeting at 9 a.m. on July 31 in the board chamber on Low Gap Road in Ukiah in order to address local emergency needs and the local emergency declaration issued yesterday. Gov Brown also declared an state emergency for these fires yesterday, and FEMA will also be providing assistance.
Here’s the map:
RanchFire-29-JUL_1045The Ranch Fire has been moving towards Highway 20, and CalFire is working on improving containment and doing dozer work and structure protection. One of today’s goals on the fire will be to prevent the Ranch fire from going further north, or from getting into the Middle Creek drainage area (see video for map).
Yesterday the high temperatures and windy conditions meant that fire fighters saw some long-range spotting, including up to distances of a mile in advance of the fire, including around one of the repeaters near the Middle Creek drainage. In the video, the battalion chief notes that this is “significant infrastructure” and that it is believed most of the repeater was saved and operating, although CalFire has not yet returned to the scene.
The River Fire made a strong run towards Lakeport to the east yesterday, but firefighters succeeding in establishing dozer lines to the east of the fire, about at the western edge of the unincorporated sections of Lakeport. Mandatory evacuations remain in place for these unincorporated areas west of Highway 29. Lakeport is under an evacuation advisory. CalFire will also be working to make sure the fire does not jump Highway 175 on the southern edge of the fire. Much of the work on the northern parts of the River Fire will take place on BLM lands establishing dozer lines.
The shelter at the Twin Pines Casino in Middletown is now closed. Sutter Lakeside Hospital is open and operating normally, but there will be no elective surgeries tomorrow.

A view of the Ranch Fire flaring up as the sun went down. Facing east from Potter Valley. – A.F. Baumann
MENDOCINO Co., 7/29/18 — Both the River Fire and the Ranch Fire — the two distinct fires known as the “Mendocino Complex” — continued to grow overnight, with the Ranch Fire surpassing the River Fire in size. The Ranch Fire, located to the north of Highway 20, now covering an area from eastern Potter Valley to about Hwy. 29 in Lake Co. stood at about 5,000 acres last night, according to CalFire. CalFire is now stating that that fire has grown to 13,242 acres — it is unclear how much of this growth occurred overnight, and now much is a result of better mapping as CalFire brings in new resources and sets up a command center.

The CalFire command center at Factory Pipe.
The River Fire, which began along Old River Road south of Ukiah and spread quickly east towards Lakeport, is now being listed at 11,028 acres. Both fires remain at 5% containment.
Also, the Federal Emergency Management Agency (FEMA), signed a fire management assistance declaration to bring federal support fire fighting efforts across the state.
The new CalFire fact-sheet lists the same areas as being under evacuation orders, or evacuation advisory, as had been placed under those statuses as of last night.

For the Ranch Fire that includes the south eastern section of Potter Valley, from Eastside Potter Valley Rd. and south of Burris Lane to the fire lines. Also, north of Hwy. 20 from the fire line all the way to the Lake Co. line. In Lake County the areas of Blue Lakes, Bachelor Valley, Witter Springs, and other sections north of Hwy. 20 are evacuated. Check the fact-sheet below for more details.
As for the River Fire, the area to the east of Old River Rd. remains under evacuation, and effectively most of the area west of Lakeport from the 29 to the fire is evacuated. Lakeport itself remains under an evacuation advisory. For more details consult the fact-sheet below.
The number of structures threatened by the two fires is now at of 4,587, and four structures have been destroyed by the two fires.
The CalFire update notes that crews continued to work throughout the night to improve containment lines, but that dry and hot weather will continue to be a challenge, and that “a lack of available suppression and overhead personnel will also slow the fire fighting efforts.” Firefighting resources around the state are currently stretched thin due to multiple fires blazing.
Here is our coverage from yesterday, with lots of minute by minute details:
A fact-sheet was put out at about 7a.m., but a new one with a correction was issued at about 8:30 a.m., so here’s the even newer. (Quick note, this is a PDF, if you mouse over it you’ll see some controls, including arrows in the lower left corner, those arrows let you go to the next page.)
Incident Update CORRECTED 7.29-2
Great report. Thank you for the clear, updated infirmation.
Do we have an estimate of when Hwy 20 will be open and when we can access our properties to see if structures are still standing? Thank you.
Not yet, we will be sure to announce it when they re-open the roads.
