The Diamond Complex is a complex of fires started by lightning on July 16th, 2024, burning on the Diamond Lake Ranger District on the Umpqua National Forest. The United States Forest Service and Douglas County Sherriff are working in partnership with a Complex Incident Management Team to manage these fires. Fire managers are employing a full-suppression firefighting strategy, while working to minimize risks to responders and the public. 

The forest has issued a fire area closure. Only the KOA campground is open at Lemolo Lake. They also implemented Level 3 public use restrictions due to very high fire danger. 

Level 3 - GO NOW - and Level 2 - BE SET - evacuations are in place for parts of the Trail and Pine Bench fire areas. Lemolo Lake has been downgraded to a Level 1 - BE READY.  Updated information and an interactive map are available on the Douglas County Sheriff's Office website.

Fuels Involved

Fuels include: timber (litter and understory); closed timber litter; and brush (two feet)

Timber fuels (mixed conifers) with a mix of timber litter and understory are present throughout the fire complex area.
Past fire footprints of varying age consist of grass, brush, and heavy dead fuels, both standing and fallen. Dead fuels
remain seasonably dry, but are drying quickly, and live woody fuels are contributing to overall fire behavior. Canopy
moss and lichens are widespread.
Significant Events

Observed fire behavior today: Active flanking, backing, isolated torching.

Limited activity most of the day with mostly creeping and smoldering due to regional smoke. This served to raise RHs throughout the fire area. By mid-day some flanking and isolated torching observed. Slightly higher RHs in the mid-30s with some in the 40s observed at lower elevations. The heavy down fuel component holding heat was sufficient to continue spread on the higher elevation fires (Pine Bench/Potter) primarily by flanking and backing. Other fires were still showing creeping but resistance to control remains high as new spots are found or interior green patches flare up. 
Outlook
Planned Actions

Continue constructing direct line around the Ooya Fire to lock it in its footprint. Continue indirect line
construction around Pine Bench and Potter. Both those actions will provide protection to Pacific
Power infrastructure. Finish structure protection on Pacific Power infrastructure and residences in the area.
Scout and re-evaluate the Bear Trap fire to prevent new threats to the Diamond Lake area. Address heat
found on the east side of the Trail Fire with direct tactics and mop-up
Projected Incident Activity

12 hours:Minimal activity expected on lower elevation fires and with the higher elevation fires (Pine
Bench/Potter/Ooya/Trep) some flanking and isolated torching is possible at the ridgetops where RHs
have been running slightly lower

24 hours:  Conditions moderate with min near 40 and light WSW winds. Fingering and flanking runs will be
possible under a shorter burn period but growth will be dependent on clear air from regional smoke.
Ridgetop fires will still see some activity with flanking, backing, and isolated torching.   

48 hours:  Conditions moderate with min RHs near 40%, temps in the low 70s and continued light WSW winds.
Fingering and flanking pushes will be possible under a shorter burn period but growth will be
dependent on clear air from regional smoke.

Current Weather
Weather Concerns

t was a cool morning with temperatures in the 40s and excellent humidity recovery for most of the fire area. There was enough clearing
early in the day to allow temperatures to climb to near 80 degrees and the relative humidity to fall to around 30 percent. Light winds at the
surface and aloft eventually allowed smoke to fill across the area during the afternoon. It will be a little cooler with higher humidity on Monday,
and there will be an uptick in winds from the west-southwest around 10 mph gusting to 20 mph along the ridgetops. There will also be an increase in wind gusts that channel through the complex terrain.
