Situation Update: N51705 - Trozzo Creek
19:00 on July 29, 2021
Observed fire Behaviour: Rank 3 Size: ~4380 hectares
General Objectives:
1- Contain the western flank at Elliott Anderson FSR connecting with Trozzo FSR at 5.5km.
2- Increase containment depth in the Trozzo Creek drainage.
3- Establish contingency lines north of fire.
4- Plan containment lines south and east flanks, implement once western flank is contained.
Resources
• 90 firefighters and single resources
• 21 heavy equipment
• 5 helicopters
Success
• 15% of the fire is contained, predominantly in the Trozzo Creek drainage.
• Guard construction along the top of Elliot Anderson Ridge from ~8 km Elliot Anderson
FSR shoulder to 5km Trozzo FSR is 100% complete.
• Further mop-up along the Elliott ridge, and in the Trozzo Creek drainage.
• At this time (19:00 July 29) the fire has not jumped the Lemon Creek FSR.
• 80% completed contingency guard along the Ponderosa FSR to Dayton FSR.
• Plans and implementation of containment lines along the north and north east sides are
ongoing utilizing the Lemon Creek road series and Holmsen drainage.
Challenges
• The lack of water sources at higher elevations, and the rough FSRs slows the delivery of water by rock trucks and tenders.
• The volume of dead and down trees at higher elevations is a significant driver of fire
behavior.
• Steep, rocky and complex terrain of Trozzo and Lemon Creek drainages makes guard
location and construction an ongoing challenge.
• Dense smoke limits visibility for fixed wing aircraft to safely access the fire.
• The July 21st late evening fire growth into the Lemon Creek Drainage initiated a tactical evacuation of residents on (Rooster Road and Popou Road). An Evacuation Order was put in place by the Regional District.
Objectives for tomorrow:
• **NEW** Hand ignition along 3 to 4 km on Elliott FSR to increase reliability in containment along this area.
• Continued guard construction on Lemon FSR, and Ponderosa FSR up to the fire lookout tower continuing North tying into Dayton FSR road series.
• Continued fire suppression along Elliot Anderson FSR utilizing burn outs, hose lays and sprinkler lines supplied from water tenders, skidders, and helicopter buckets.
• Mop up to 100 ft deep along the contained fire edge in Trozzo Creek drainage.
• Monitor fire growth towards the east (Baldface Creek) and South (Sproule Creek)
• Continue to establish helipads and fire containment south of Trozzo FSR moving down into Winlaw Creek drainage.
Plan for aviation resources:
• Reduce fire intensity and spread downslope towards mouth of Lemon Creek drainage.
• Hold fire at top of Elliot Anderson Ridge to Trozzo Creek drainage.
• Monitoring flights
Plan for heavy equipment:
•Continue construction of contingency line, Ponderosa FSR to Dayton FSR road series.
• Further bolster the containment lines in place along Elliot Anderson - Trozzo FSR guard.
• Create containment lines into the Lemon, South Lemon and Holmsen drainages to hold
fire from crossing Lemon Creek utilizing the road series.
• Support crews by filling bladders with water tenders and skidders
Structures currently threatened? Yes
• Residents near Lemon Creek (closest structures approx. 700 meters downslope) – Evacuation Order in affect
• Community of Winlaw (closest residents 3.5km to the W)
• Baldface Lodge 6km to the E
• Sproule Creek residents 8km to the S
