The Nottawasaga Valley Conservation Authority

​​​​​​Flood Forecasting & Messages​

NVCA monitors weather conditions and river flows to determine if there is a risk of flooding.

If there is, we issue flood messages to alert municipal flood coordinators and the public about flood risks. The coordinators then implement their own local flood response plan and assist local residents and other key partners.

Flood messages are also sent to radio stations, televisions stations and newspapers in the Nottawasaga Watershed and surrounding regions. Media outlets usually post these messages on their websites.

Residents can also follow NVCA on social media or subscribe to our flood newsletter to be notified when flood messages are issued.

NVCA can issue three types of flood messages:​

Watershed Conditions Statement

There are two variations of these.
