Polygon features representing the observed, derived or estimated inundation extent for floods that have occurred in Victoria. These are not linked to modelled flood data.
Confirmed flood observations are derived from the automated and manual processing of data from the sources listed below. Note that while flood observations have manual oversight and corrections during the event, they are based on a point in time and may not necessarily represent the maximum flood extent.
- Aerial photography
- AIG observation
- Air observation
- Linescans
- GPS
- Ground Observer
- Satellite imagery interpretations
The derived flood extent is from automated and manual processing of satellite data. This data is usually used to fill in gaps outside of areas covered by confirmed flood observations.
Note that this flood extent data was prepared by the SCC Mapping Team for operational use only. It may have missing or incomplete data that could lead to gaps in analysis or visualisations. The dataset does not capture the peak flood extent in all areas. The dataset does not capture the extent of flash flooding.
Past and future layers may be added as the data becomes available. List of events included in Supplemental Information

Not Known
Data Source:
Data Source: Available remote sensing data at the time of each flood event. Flood extents have been derived from a wide range of sources, including but not limited to electro-optical satellite imagery, synthetic aperture radar satellite imagery, linescans, aerial optical imagery, handheld imagery, aerial observations, and ground-based observations. A combination of both manual feature and automated feature extraction methods were used to derive the flood extents from these sources. Managed by CMAs, VicSES and DEECA

History: Initial release May 2023 - loaded Oct 2022 flood extent across Victoria derived from various datasets available through the State Control Centre.
22/08/2023 - The Oct 2022 flood extent dataset was updated to improve completeness. The updated version includes observed flood extents both in the proximity of Maribyrnong and to the east of Seymour.
