The Detwiler Fire continues to burn in Mariposa county near Yosemite National Park, causing road closures and evacuations. The fire has almost tripped in size over the past three days, growing from 25,000 acres to its current size of more than 70,000 acres. Currently, the fire is only 10% contained.ย Firefighters have called the fire “extreme and aggressive,” and Governorย Jerry Brown has declared a state of emergency.
Winds have moved smoke from the fire north, directly into the Lake Tahoe basin. Check out this satellite video below to see why the Tahoe air quality hasn’t been so great over the past couple of days.
“The Eastern portion of El Dorado County is under an AIR QUALITY ALERT and a DENSE SMOKE ADVISORY by the U.S. National Weather Service (NWS), although the majority of the County may see effects of the smoke from the Detwiler Fire in Mariposa County.
Persons with respiratory illnesses should remain indoors to avoid inhaling smoke particles. Keep windows and doors closed to avoid letting the smoke inside buildings.
Due to elevated particulate pollution levels, children, the elderly, people with heart or lung problems, or people with current illnesses such as the flu, are advised to stay indoors and avoid strenuous outdoor activities in the impacted areas.

The fire started on Sunday, July 16, 2017, at 3:56 p.m. and is currently at 70,096 acres in size with 10% containment achieved according to CalFire.
The acreage increased due to an increase in fire activity late yesterday afternoon. Overnight, fire crews continued their work to establish and reinforce containment lines. The fire area is seeing poor humidity recoveries at night allowing the fire to remain very active throughout this time. The fire is burning in drought stricken chaparral and in an area of severe tree mortality. Damage assessment crews are on scene to evaluate and inspect the area.
Power lines supplying power to Yosemite National Park continue to be threatened.
If you have questions about the fire, please call the Fire Information Line at (844) MMU-FIRE.
