Dataset: Frequency of Commonwealth environmental water - wetland and floodplain inundation 2014-2021


Extent of surface water (outside of river channels) thought to contain Commonwealth environmental water either alone or in partnership with other water holders. Mapped as the annual frequency of inundation. Raster data set derived from Landsat and Sentinel-2 observations of water extent checked annually with water managers. Excludes natural flooding and inundation by other sources of environmental water where there was not a component of Commonwealth environmental water.

Compiled by the Commonwealth Environmental Water Office's (CEWO) Flow-MER Program.

2014-2019 data based on information from the Long Term Intervention Monitoring (LTIM) project.
