Lightning Creek Trail with smoke from strategic firing operation

On August 5, 2024, a storm with lightning moved through the area with a series of ground strikes, igniting the Middle Fork Complex (consisting of the Bulldog Fire, Nellie Fire, and Anderson Fire). The Anderson Fire was the first fire reported on August 5, 2024 at 4:16 PM, followed by the Bulldog Fire at 5:03 PM, and the Nellie Fire on August 6 at 8:29 PM. 

On August 12, the Nellie and Anderson fires merged and began being managed as one fire, retaining the name Nellie. The fires are burning in steep, rugged terrain, making access difficult in some areas. Ensuring firefighter safety and protecting life and property are of the utmost importance.

Moving forward, the Nellie and Bulldog fires are now referred to as the Middle Fork Complex.

The Bulltrout and Wapiti fires are being managed separately as of Saturday, August 24, 2024.

Fuels Involved

Primary Fuel Model, Materials, or Hazards Involved (hazardous chemicals, fuel types, infectious agents, radiation, etc):

Timber (Litter and Understory)

Brush (2 feet)

 

Narrative:

Fuels are primarily timber (litter & understory) and brush with isolated patches of open grass. Fine dead fuels, timber litter, and 1000-hr fuels are the main carriers of fire. Live woody shrubs are available for consumption. Energy Release Component is over the 90th percentile.

Significant Events

Observed Fire Behavior or Significant Events for the Time Period Reported (describe fire behavior using accepted terminology. For non-fire incidents, describe significant events related to the materials or other causal agents):

Moderate

Backing

Flanking

Group Torching

Narrative:

Active fire behavior later in the burn period driven by SW winds, high temperatures and low RHs across the fire area. Backing and flanking with increasing episodes of torching after 2:00 PM are the primary observed fire behaviors. Short, terrain driven runs and group torching are also happening later in the burn period.

Outlook
Planned Actions

Planned Actions for Next Operational Period:

Crews that were scouting indirect line on the ridge above Silver Creek Plunge are assessing additional efforts to assist with working around structures to create defensible space for operations. Additional crews are being loaned from neighboring divisions to help with implementing fuel mitigation for Boiling Springs and Silver Creek Lookout in anticipation of Goat Fire movement south. Scout for opportunities to check northward progression of Bulldog fire.

Indirect line construction through the Lightning Fire scar towards the south is finished. Scout for opportunities to reduce fire movement to the south and west. Potentially continue to conduct strategic firing operations consistent with approved aerial ignition plan to mitigate fire effects in the Lightning Creek drainage complex. This is interior firing to improve the viability and success of utilizing the primary indirect fire line when needed. Coordinate with other crews for ingress/egress and fire line placement. Additional crews on loan from neighboring divisions to assist in completion of indirect line to connect Bulldog and Nellie fire through Lightning Creek. This is where the need for more experienced Interagency Hotshot Crews exists in case the indirect line needs to be put into use. Holding this line is critical for protection of the communities of Crouch and Garden Valley.

Crews southeast of the fire continue to hold and mop-up dozer and handline from Anderson Creek to Highway 17. Fire line repair has been started and line will continue to hold and control the fire edge.

Crews on south end of fire assisting with holding and mopping up dozer line along Highway 17 to Anderson Creek.    

East side of the fire saw moderate fire activity continuing on the northern half of the division but overall the fire is making little progress through the Pioneer burn scar.

Deadwood Reservoir has Type 2 Initial Attack and Type 2 crews implement direct suppression tactics to prevent further fire spread on east and west side of Deadwood Reservoir. Construct indirect line to the north using the 555 road towards Deadwood Outfitters. Dozer line has been constructed on the western side of the fire, south of Deadwood Reservoir, to help secure fire edge into the Rattlesnake burn scar. Continue to hold and mop-up previous firing operations in the Deadwood Dam area. The structure protection on Whitehawk Mountain lookout has been completed.

The Structure Group will continue to assess and mitigate hazard fuels around structures. Resources in the Structure Group will be utilized to assist with IA Response.

 

Projected Incident Activity

Red Flag Warning for thunderstorms and dry fuels is possible prior to precipitation arrival by early afternoon. Strong gusty winds on our dry fuels and steep slopes could lead to rapid rates of spread.  After frontal passage fire behavior should return to flanking and backing with significant smoldering. General SW winds align with fuel and terrain. Low fuel moistures will continue to support fire behavior, particularly where direct sun is present.

Current Weather
Weather Concerns

Weather Concerns (synopsis of current and predicted weather; discuss related factors that may cause concern):

On Tuesday, smoke continued in the valleys/drainages until mid to late afternoon with clearing at mid/upper-slopes and above late morning to early afternoon. Southwest winds increased during the afternoon, gusting 20-25 mph at ridgetops. Shallow cumulus developed and high clouds moved in during the afternoon. Temperatures were in the mid 70s to 80s with RH mostly in the teens.

12 Hours: Light drainage winds in valleys are expected overnight along with slightly better RH recoveries of 40-70% as an inversion develops and moisture increases ahead of a trough. Temperatures will drop primarily into the 50s and perhaps upper 40s in the valley bottoms. There is a slight chance of isolated showers and thunderstorms early in the morning.  

On Wednesday a Red Flag Warning will be in effect for scattered thunderstorms over dry fuels. Showers and thunderstorms may develop as early as the morning, with multiple rounds possible through evening. Gusty outflow winds up to 60 mph and hail are possible across the area. Debris flows and flash flooding are also possible under the strongest thunderstorms or where multiple thunderstorms pass over the same area, especially on steep slopes with high burn severity. Temperatures will be cooler with highs only reaching the 60s to mid 70s, and RH only dropping to 25-40% under mostly cloudy skies. Rain showers will increase overnight, with high chances of wetting rain on much of the fire.

On Thursday rain is likely through the morning, with rain chances ending Thursday night. Temperatures will be well below normal, with highs in the 40s and 50s and minimum RH above 60%. Winds will be mostly terrain driven but out of the northwest at ridgetops with gusts of 15-20 mph.
