Fires of note

The Rinker Lake Complex – Thunder Bay 36 (THU036), Dryden 34 (DRY034), Dryden 35 (DRY035)

• Fire activity across the complex has remained on the lower end of the spectrum in recent days although smoke remains visible in some areas.
• Thanks to ongoing suppression efforts, all three fires in the Rinker Lake Fire Complex are now being held.
• THU036 is currently measuring 301,240 hectares and is now being held.
• DRY034 is currently measuring 45,800 hectares and is now being held.
• DRY035 is currently measuring 30,158 hectares and is now being held.
• This change in status indicates that with currently committed resources, sufficient suppression action has been taken so that the fire is unlikely to spread beyond existing or predetermined control boundaries under current or forecasted conditions.
• As a result of the status changes, this will be the final update that will include the Rinker Lake Complex among the fires of note.
