Since record keeping began there have been nearly 40 significant floods in Launceston with the 1929 floods being the most significant.

While areas like Invermay are protected by flood levees, new buildings are increasingly being engineered to withstand floods, and residential developments are limited in some areas, we can't risk complacency.

This week the City of Launceston will carry out routine testing of the Charles Street Bridge Bauer flood gate.

This is one of around 20 flood gates that are closed in the event of a serious flood risk to the city, connecting our 12-kilometre flood levee defence system.

Such exercises allow us to train new staff and test our equipment and procedures. They also serve as an important reminder to the public about flood risk in our city, and the importance of being prepared. If you live in a low lying part of Launceston, there are some simple steps you can take to ensure you are well prepared in case of flood.

Pick up a free copy of the Flooding in Launceston information pamphlet from the City of Launceston's Town Hall customer service centre, or download the digital version from our website.

Have an emergency kit prepared in a waterproof storage box. An emergency kit might include items like waterproof clothing, blankets, non-perishable foods, bottled water, a first aid kit, and spare toiletries.

Pre-arrange with friends or family to look after pets so you that your furry friends have a safe place to go in an emergency.

Familiarise yourself with the state government emergency website Tas Alert and stay up to date no matter the season - remember that a flood can occur at any time of the year.

A flood gate exercise will take place on Thursday, and requires the Charles Street Bridge to be closed from about 7.30pm to 9.30pm.

Traffic from the south will be diverted along Cimitiere Street, across the Tamar Street Bridge and into Lindsay Street.

During the closure, traffic from the north will be diverted along Lindsay Street, across the Tamar Street Bridge and into Cimitiere Street. Pedestrians will need to use either the Tamar Street bridge or the Seaport pedestrian bridge.

Floods have impacted Launceston in the past and will again in the future. If you live in a low-lying part of Launceston, discuss this risk with your family, make a plan for your pets, and be prepared.
