Carbon County Floodplain Maps Update

Note:  Due to June 2022 Flooding, this floodplain map update project is currently on-hold.  We will post updated information as it becomes available.

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. 

For more information, see: Background on existing floodplain maps and Flood Study Process

DNRC held project kick-off meetings on October 3rd & 4th, 2019 with Carbon County, Joliet, Red Lodge, Bear Creek, and Fromberg. To view the slides that were presented: click here. 

Below are the study extents for the project. To view a larger image click here. 

Below is a tentative project timeline - NOTE:  this timeline has been affected by the June 2022 flooding events, It will be revised when more information is available
