Carbon County Floodplain Maps Update


Carbon County is working with MT DNRC and FEMA to update flood studies and floodplain maps for the Clarks Fork of the Yellowstone, Rock Creek, and tributaries.  Updated floodplain maps will depict the latest, most accurate flood risk data, and will be used to eventually replace some of the existing FEMA floodplain maps in Carbon County.
