Powell County Flood Maps Update


Powell County City of Deer Lodge 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 Clark Fork River, Blackfoot River, Little Blackfoot River, Cottonwood 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.

2020 Project

DNRC with support from Powell County applied and received a grant from FEMA to update and produce new Flood Insurance Rate Maps for the county. 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 from the 1970s.

Meetings:

A project kick off meeting was held with the County Commissioners  on 9/28/2020.

A project kick off will be held with the City of Deer Lodge tentatively 10/22/2020 at the community center. 

Below are the study extents for the project.

The project timeline below is just an estimate. Weather can delay data collection, data review and revisions can require some back and forth, but if the project goes according to plan below is the tentative project timeline.
