Teton County and the City of Choteau have been working with the Federal Emergency Management Agency (FEMA) and Montana Department of Natural Resources and Conservation (DNRC) to update and produce new floodplain maps for the Teton River, Sun River, Spring Creek, Deep Creek, Muddy Creek and Tributaries.

Many of the existing floodplain maps are based on data from the late 1970s.  Updated Flood Insurance Rate Maps will provide more accurate, current, and detailed data and mapping of flood risk areas. For more information on the background of the floodplain maps click here.

The draft study information and maps need to go through a lengthy technical and public review process before being finalized. When finalized, new maps could have effects on property owners in mapped floodplains.

DNRC with support from Teton County applied and received a grant from FEMA to update and produce new Flood Insurance Rate Maps for the county and city. Updated floodplain maps will depict the latest, most accurate flood risk data, and will eventually replace FEMA’s existing floodplain maps which are based on data collected in the 1970s.

Below are the study extents for the project.
