Fire growth was minimal overnight due to the settling of the nighttime inversion and the low speed diurnal flow patterns. No fire growth occurred in the northwest, west, and south areas of the fire. Minimal spotting was observed from single tree torching overnight. These were safely contained due to the decrease in fire activity. Minor growth was seen in Div I and Div N.

WEST ZONE:

Provide for the life safety of citizens and emergency responders. Implement structure and critical infrastructure defense. Construct control lines and take advantage of targets of opportunity as allowed by fire behavior and resource limitations. Improve and hold established control lines. Prepare for firing operations and implement burn plans. Identify and establish contingency lines. Tactical patrol of perimeter contained.

Heavy mop-up, backhaul of hose, and patrol will continue in areas of DIV A and D. Contingency lines will continue to be constructed in DIV I, and Contingency Branch from Ice House east to the DIV I break. Preparations for potential firing opportunities will occur in DIV N and P. Fire Suppression Repair continues to evaluate repair needs and will implement the Incident's Fire Suppression Repair Plan.

EAST ZONE:

In the Christmas Valley area crews will remain engaged in constructing direct containment lines and aggressive mop up from Highway 89 west to Scout Peak to reduce the threat to structures.

In the Pioneer Trail area, resources will continue to patrol and mop up as necessary.

On the northeastern side of the fire in the Cold Creek Drainage area, resources will strengthen existing fireline and continue to

use a combination of direct and indirect tactics, working with local utility companies to open road systems to connect to dozer lines to prevent continued fire spread to the northeast.

On the southern flank of the eastern finger of the fire, a combination of direct hand and dozer line is being constructed to keep fire from moving to the south and east.

In the northwest part of the zone, crews will continue to construct direct fireline from Highway 50 toward Lower Echo Lake. In the Lower and Upper Echo Lake areas, structure prep and line construction operations are ongoing.

Crews will work in the Desolation Wilderness to contain the northwestern corner of the East Zone.

A contingency group is locating and building contingency lines to the northeast of the fire in the event of fire crossing primary

containment lines. Mastication and chipping are occurring on road systems south of the east zone of the fire. Crews are also masticating roads in the Fallen Leaf Lake area for contingency purposes.

Planning is occurring to mitigate potential threat to communities in the Foothill Road area east of the fire.

A Fire Management Assistance Declaration was declared on August 17, 2021. Incident Period: August 14, 2021, and continuing. (FM-5413-CA) The Governor of California declared a State of Emergency for El Dorado County on August 17, 2021, due to the Caldor Fire.

The Eldorado National Forest is closed from August 17, 2021, through September 30, 2021. (Forest Order No. 03-21-14) To better provide public and firefighter safety due to the ongoing California wildfire crisis, USDA Forest Service Pacific Southwest Region announced a temporary closure of all National Forests in California from Aug. 31, 2021 through September 17, 2021.

CAL FIRE IMT-6 and NIMO-2 are in command of the West Zone and CIIMT-4 is in command of the East Zone. CAL FIRE IMT-2 will

transition with CAL FIRE IMT-6 and assume command on Wednesday, Sept 8th at 0700 hours.

Fuels reduction projects that have been implemented around the community of South Lake Tahoe have been highly effective in providing opportunities for resources to successfully suppress fire.

WEST ZONE:

Observed: Inversion conditions set up again around 2100 and continued through the night. Downslope and down canyon winds developed at around 2100 and prevailed through the night. Lows ranged from 49-59 over the higher elevations to 59-66 in lower drainages. Relative humidity was poor reaching only the 20-25 percent range.

Forecast for Saturday: Sunny with areas of smoke. Inversion breaking by 1200. Highs 74-84 upper elevations and 84-93 lower drainages. Winds downslope down canyon through mid morning then becoming upslope and up canyon 5 10 mph with gusts to 15 mph in the afternoon. Gusts to 25 mph possible along the Highway 50 corridor. Relative humidity minimums 10-15 percent.

EAST ZONE:

Observations: Strong inversions formed overnight with very poor humidity recoveries only reaching 20 to 30% along the mid-slopes and ridgelines and above 6600'. Good recoveries occurred in the lower valleys. Ridge winds remained variable with downslope terrain driven winds over the rest of the fire area.

Sunday Forecast: Extremely dry air will remain over the fire area on Sunday with above average temperatures continuing through Monday as high pressure remains over the west. Humidities will drop into the low to mid-teens at all elevations again during the day with very poor recoveries on mid-slopes and ridges. Ridge winds will remain variable, keeping smoke over the fire. Surface winds remain terrain driven with upslope winds 4 to 8 mph during the afternoon and gusts up to 15 mph in canyons. A return of southwest winds is expected by Tuesday with ridge wind gusts up to 25 to 30 mph possible.
