DENVER — New flood insurance rate maps for the Musselshell River in portions of Petroleum County are nearing completion. The new maps will provide more accurate flood risk information that can help local officials and residents make informed decisions about reducing flood risks and purchasing flood insurance.

The mapping project was initiated by Petroleum County and the Montana Department of Natural Resources and Conservation (DNRC). It is part of a nationwide effort led by the Federal Emergency Management Agency (FEMA) to increase local knowledge of flood risks and support actions to address and reduce those risks.

“Until now, Petroleum County has never had floodplain maps for the Musselshell River” explained Tiffany Lyden, DNRC Floodplain Outreach Specialist. ”Developing new, accurate floodplain maps is a key step in providing accurate information to help keep families, homes, businesses, and infrastructure safe from future flood events.”

Before new flood insurance rate maps become effective, there is a 90-day Appeal Period during which local residents and business owners can provide additional data for consideration before the maps are final. This appeal period starts on October 18, 2018, and ends January 15, 2019.

Petroleum County officials encourage residents and business owners to review the proposed flood insurance rate maps to learn about local flood risks, potential future flood insurance requirements, and any concerns or questions about the information provided. The proposed maps can be viewed online at or at the Petroleum County Courthouse.

If you have technical and scientific information, such as detailed hydraulic or hydrologic data, you may be able to appeal the flood risk information on the proposed maps during the 90-day Appeal Period. For further details on this process, visit or contact Jay King, Petroleum County Planning Board member at 406-380-0807.
