Officials with the Rocky Mountain Ranger District provided updated information on Tuesday afternoon about several fires burning in western Pondera and Teton counties.
Lightning is believed to the cause of all four fires.
There are two public meetings scheduled for residents to get updates on the situation:
The Pondera County Sheriff's Office initiated mandatory evacuations for several residents between Swift Dam and the Karl Rappold Ranch, the Birch Creek Area, and Seven Mile Lane. The increased fire activity prompted the Sheriff to initiate evacuations for four to five ranch owners in the vicinity of Swift Reservoir and the dam keeper's residence.
A pre-evacuation notice was issued for homes farther east along Swift Dam Road toward Dupuyer. A pre-evacuation notice tells property owners to be ready to leave on short notice. Pre-evacuation calls are also being made to people living in Dupuyer, as the fire begins to spread in the directions.
They ask that anyone who evacuates their property to tie a ribbon or colored twine on their fence posts to let responders know you have left the property.
A shelter has been opened at the Fireman's Pavilliion at Lake Frances near Valier.
Montana Fish, Wildlife and Parks has closed Lake Frances near Valier while crews use lake water to fight nearby fires. FWP says that the closure applies to all recreation, including boating, swimming, wading, and fishing.
The closure is to ensure public safety so that aircraft crews can safely operate as they dip water from the lake. The closure will be in place until fire crews no longer need to use the lake for suppression efforts.
