Floods

Stay informed using Everbridge

Flash flooding occurs with little to no notice, so it is important to be prepared! Have at least three ways to be notified of severe weather. The Northeast Kansas Regional Notification System, Everbridge, will send notifications to you directly by text, phone, and/or email. It is free to sign up. 

Traditional media, weather apps, and NOAA weather radios are also good sources of information for weather updates.

Floodplain Information

What is a floodplain? 

Land adjacent to streams and rivers which does not carry water under normal weather conditions.

What does it do?

During large storm events, streams, and rivers use the floodplain to temporarily store and convey water until the storm stops and water downstream has had a chance to go down.

How are they formed?

Naturally and over time with each storm event.  Floodplains, rivers, and streams are constantly changing by the force of Mother Nature, even during small rain events.  Water moves soil every time it rains or snow melts, constantly changing the landscape.

Do you know if you live in a floodplain?

Check the Riley County Flood Hazard Area map or the FEMA floodplain map. Type in your address for more information about the area around your home.
