Final Missoula County & City of Missoula Floodplain Maps
*UPDATED MARCH 16, 2015
The Missoula County and City of Missoula floodplain maps have been updated in conjunction with a nationwide effort to modernize floodplain maps for flood prone communities. Missoula’s floodplain maps had not been updated in over 25 years. The updating project for Missoula, begun by FEMA in 2004, converts Missoula’s existing paper floodplain maps to digital maps. In some areas, detailed mapping studies were also conducted, incorporating survey work, hydrologic and hydraulic analyses and updated mapping to identify flood risks. Because the new floodplain maps are digital, more accurate flood risk information will be more easily accessible for individual properties.
Release of the draft flood insurance rate maps on July 25, 2013 marked the beginning of the community review process during which citizens and local officials provided comments or appealed the draft maps and information. The public comment period closed on January 21, 2014 and FEMA has completed their review of the submitted comments and appeals. FEMA's review resulted in changes to seven (7) floodplain maps which are identified with "2014" on the pdfs available below. On January 6, 2015, FEMA issued their Letter of Final Determination indicating that the 2013 draft maps as amended in 2014 will become effective on July 6, 2015 for flood insurance purposes. Before the effective date, Missoula County is required to amend our current floodplain regulations. Missoula County will soon be issuing a draft updated floodplain regulation for public review.
The final floodplain maps for Missoula and Missoula County are available for public viewing in Missoula at the Land Services Department in City Hall at 435 Ryman, Community and Planning Services at 323 W. Alder and the DNRC Regional Office located at 2705 Spurgin Road, Building C or online - see below.
The final maps are also available on DVD (for a cost of $1.00) at the Community and Planning Services Office at 323 W. Alder, or you can also bring in a flash drive and we can load the maps on it for free. There is an Index that helps determine which maps you may want to view.
More information is provided in the Flood Insurance Study documents.

Clark Fork River Channel Migration Zone - Pilot Study
When someone has lived along a stream for a few years and it doesn’t appear that the stream has moved, they may be lulled into thinking that it might stay that way forever. But the fact is that streams naturally migrate across their floodplains over time and in response to large events such as floods, debris or ice jams. Former active river channels are readily visible in aerial photos of the Missoula Valley. Historic photos show a long term pattern of channel migration. Despite our best efforts to control them, streams often reclaim their former channels and floodplains, potentially resulting in catastrophic loss of life and property.
In December, 2009 the Missoula Water Quality District released a pilot channel migration study for a stretch of the Clark Fork River downstream of Missoula to Huson. The study documents where the channel has been historically - and where it may be again within the next 100-years. The study and associated maps are available for download here:
