The Montana floodplain mapping program helps communities across the state identify flood risks. 

Identifying flood risk can help keep your home and local community safe from future flood events. Floodplain maps should be your go-to tool in learning about your risk. Flood risk changes over time, floodplain maps will require periodic updates. This could be because of the age of the flood study or if there has been a lot of change or development in the area, or it could be because of a flooding event. Flood studies now are done in collaboration with communities, DNRC, and FEMA.
