Flood Safety and Protection Tips

What is a flood?  What causes flooding?  How do you read a flood map?  The FloodSmart.gov website is an official site of the National Flood Insurance Program that provides useful information for residential and commercial property owners including an interactive Risk Assessment Tool.  Additionally, interested persons can monitor local river levels through the USGS Stream Gauges website on current conditions in Montana.

A floodplain is a generally flat area of land next to a river or stream.  A floodplain consists of the main channel of the river (floodway) and the area beyond (flood fringe).  

Floodplains are unique and provide a number of natural and beneficial functions

Riverine and shallow flooding can occur in Missoula.  Riverine flooding occurs when a channel receives too much water causing excess flow over its banks and into the adjacent floodplain.  Shallow flooding occurs when a lack of channel means water cannot drain away easily.
