Mosquito Fire
News - 09/26/2022

Size: 76,781 acres

Containment: 85%
Total Personnel: 1,248



Yesterday, hot and dry conditions persisted across the Mosquito Fire and as a result, mop up efforts remained a priority with hot spots occasionally popping up within the fire footprint. Resources were prepared and directly engaged in the suppression of the hotspots and creeping fire.

Similar warm and sunny conditions are expected today, and a northerly disturbance will bring cooler temperatures later this week. The cooler temperatures are expected to bring winds; however, containment lines are expected to hold well.

Smoke production will peak during the heat of the day today. No major fire movement is forecasted. Hazard tree mitigation and suppression repair remain priority operations. Due to challenging terrain in the Middle Fork of the American River, and to the south along the Rubicon River, ground resources are unable to access and go direct. Therefore, resources are utilizing aviation assets to hold the fire in its current footprint using retardant and water.

The protection of cultural and natural resources during a fire is a high priority along with returning the affected areas to their pre-fire conditions. Management teams will engage the expertise of natural and cultural Resources Advisors (READs) to assist in preventing fire suppression damage. READs provide guidance for suppression actions as well as rehabilitation through coordination with local specialists: biologists, archaeologists, engineers, and recreation planners. Even long after the fire is suppressed, READs will remain on and work through the rehabilitation efforts with the local and national land management agencies.

A virtual community meeting will be held tomorrow, Tuesday, September 27 at 7:00 p.m. on the following websites: or on Facebook @TahoeNF or @eldoradoNF.
