Missoula Flooding Emergencies & Evacuation Areas

If you need immediate assistance contact 911. If your issue is less urgent you can reach the Missoula County Sheriff's office at 406-258-4810. For general flooding inquiries call the public information line at 406-258-4630.

To see the most up-to-date flooding, evacuation, and sandbag volunteer information visit Missoula's InciWeb. As of Thursday, June 14th the Missoula County Sheriff is maintaining a modified evacuation order for the following areas:

  • Northwest Corner of Tower Street;
  • Kehrwald Drive; and
  • Channel Drive.

Please be careful and stay safe. If you see water over-topping the road, do not drive into the floodwaters as most flood deaths occur in vehicles. Avoid contact with floodwaters and take an alternative route. Do not re-enter a flooded structure unless it has been assessed and marked as safe by either a Missoula County Inspector or a Licensed Engineer.

Need Help?

American Red Cross shelters are on standby and ready to assist in residents affected by the 2018 Floods. Residents seeking shelter should call 1-800-272-6668. 

Returning Home After A Flood

Before re-entering your home post-flood you must first receive approval from the local emergency service and have the structure deemed safe for entry by a licensed professional. In some cases a Missoula County Inspector can assess on a case-by-case basis if a structure is safe to enter. Once your home is deemed safe make sure the main power breaker and gas meter (as well as all propane tanks) are turned OFF. If returning to your property after evacuation, see Missoula County's 2018 Flood Recovery Information for Returning Residents for instructions on:

Septic Systems & Sewers

Floodwaters can cause wastewater to surface or to back up into houses on septic systems. If there is any sign of floodwaters backing up into a house, residents should clean and disinfect the area before using it. Residents also should not pump flood or groundwater into floor sinks or house drains, as that amount of water can overwhelm septic systems, leading to sewage surfacing on the ground or backing up in a house. If you see this on your property, the best solution is to plug all drains in the basement and drastically reduce water use in the house. Review the EPA's resources on septic system failures and their fact sheet on what to do once the flooding starts.

Waterborne Illnesses

See the Missoula County Health Department's tips on flooded wells, safe drinking water, and chemical storage. To safeguard against contaminated floodwaters (which may contain chemicals, sewage, bacteria, and viruses) the Health Department recommends residents ensure their tetanus shots are up to date. Prior to eating ensure your family's hands are washed with soap and water. This will help reduce risk to waterborne illness.

Areas At Risk

Low-lying or poor-draining areas may be inundated from river flooding, runoff, or an over-saturated groundwater table. As always, prepare and stay informed for coming flood conditions. See the links below.Image of NOAA’s reminder that freshly burned land can cause flash floods.

Discover Missoula's Levees & Flood Protection

The City of Missoula maintains four levees, two of which are on the Clark Fork River. These levees are structurally sound, safe, and secure. They are designed and built for 100-year flood events. City Storm Water Division staff and the City Engineer inspect them twice a year. They completed the spring inspection in April 2018. Every other year, staff from the Army Corps of Engineers join the inspection with City staff. The Orchard Homes levee is a Missoula County levee.
