What Hazards Affect Jefferson County?

The major hazards for Jefferson County are wildfire, hazardous materials, flood, severe storms, and earthquake. Jefferson County residents will receive information during a disaster through the Emergency Alert System. Radio stations in both Helena and Butte are partners in the systems, and will provide 24-hour warning information. If the system is activated those stations will be given instructions by county officials for broadcast to the public.


Jefferson County is protected by nine volunteer fire departments for both structure and wildland fires. These are located at Montana City, Clancy, Jefferson City, Boulder Town, Boulder Rural, Basin, Elk Park, Whitehall (Jefferson Valley), and Willow Creek. Jefferson County is also a member of the Tri-County Fire Working Group.

Hazardous Waste

Two Interstate Highway systems cross Jefferson County both from the North-South, Interstate 15, and from East-West, Interstate 90. These routes subject the county to transportation related accidents with the heavy movement of hazardous materials along these major corridors. Approximately one-fourth of all trucks carry hazardous materials such as gosoline, liquid petroleum gas, chlorine and anhydrous ammonia. There are, in addition, fixed facilities that store hazardous materials to be used in various industrial processes.


The county is subjected to river flooding as well as flash flooding caused by rapid moving storms. The peak of the flood season is typically the months of May and June. A rapid snow melt could cause flooding to occur earlier.For additional information about the designated flood plains in the county, contact the flood plain manager in the County Sanitarian's office.
