Flooding in Gallatin County
Gallatin County has many areas that are subject to flooding throughout the year. Primarily flooding occurs in the winter when rivers become plugged with ice, or in the spring due to rapid snowmelt and/ or rain storms. The conditions which result in flooding can occur quickly and are difficult to conduct long range forecasting for. Typically a little bit of planning ahead of time came make a big difference. The information below will provide you with how you can see current river heights and forecasts, as well as what you can do to prepare your property and families.
What Can I Do to Prepare for a Flooding Event?
First off, residents should ensure that creeks and ditches are clear of debris. Debris in waterways can cause water to back up and overflow sooner that it otherwise would. While removing simple debris is encouraged, residents should keep in mind that some modifications of the waterways may very well require coordination and permits from the Montana Department of Natural Resources and Conservations or your local conservation district.

Residents should also consider flood insurance if they live in a flood prone area. Typically, homeowners insurance does not cover damage caused by flooding. Coverage for flooding is available to most people through specific Flood Insurance policies backed by the National Flood Insurance Program. People interested in Flood Insurance should contact their insurance agent for policy information.
Each jurisdiction participating in the National Flood Insurance Program has a floodplain administrator who is responsible for the program in their jurisdiction.
