Floodplain management plans
There are a number of flood-prone areas across Western Australia and each of them can be affected at different times of the year. Floods can cause significant disruption and damage to road, rail, and communications and community infrastructure.
Since the mid-1960s, Western Australia has experienced below average annual rainfall and relatively little major flooding. Despite that, flooding remains a focus of monitoring and research.
How we manage the risk
The Department of Water works with local communities, local government and state agencies to create floodplain management plans, which outline how best to manage and assess flood-prone land and provide long-term plans for the future development of the community.
In 1975, the state government began to map major rivers across Western Australia to understand the chances of them flooding and the damage they could cause. Today, the Department of Water continues to work with agencies, industry, other levels of government and the community to understand flood behaviour and reduce the risk of flood.
