Powell County and the 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, Blackfoot, and Little Blackfoot Rivers, Cottonwood Creek, and Tributaries.
Updated floodplain maps will depict the latest, most accurate flood risk data, and will eventually result in updated FEMA floodplain maps. Many of the existing floodplain maps are based on data from the late 1970s. For More information see Floodplain FAQs and the Flood Study Process.
Project Timeline
Flood Insurance Rate Maps (FIRMs) indicate areas of flood risk. Once this project is complete, new and updates FIRMs will provide more accurate, current, and detailed data and mapping of the flood risk areas. New floodplain studies involve collecting and analyzing data, including: topography, hydrology analyses, and hydraulic analysis.
Project Updates
The flood study is complete and has been submitted to FEMA for formal review. Draft floodplain maps are available and ready for the public and community review.
Flood study data and reports can be requested through the local floodplain administrator. Draft floodplain maps can be viewed on the State Flood Hazard viewer which can be accessed below.
