Summer Air Quality Monitoring

During the summer months, generally May through October, the region can occasionally experience wildfire smoke impacts from wildfires throughout the State. The Town of Mammoth Lakes in coordination with the Great Basin Unified Air Pollution Control District (GBUAPCD) continually monitors air quality in Mammoth Lakes and the GBUAPCD and Mono County Health Department will issue Health Advisories when air quality has reached unhealthy levels.

Current Air Quality Conditions

  • Smoke Impacts: You may check current smoke impacts from active fires that are affecting the air quality in the region by visiting the GBUAPCD Smoke Impacts website.
  • Air Quality Monitoring Website: You may check particulate emission (PM-10 and PM-2.5) levels for the entire region on the GBUAPCD's monitoring station website (Clicking on a specific site will give you more detailed air quality information).
  • Air Quality Phone Line: You can call (760) 965-3640. The recording is updated as needed to transmit air quality information to the public.
