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 Flow-MER Basin scale project.
2014-2019 data based on information from the Long Term Intervention Monitoring (LTIM) project.
The CEWH’s Flow-MER program examines the contribution of Commonwealth environmental water to the environmental objectives of the Basin Plan 2012 (Basin Plan) and is assisting the CEWH to demonstrate environmental outcomes and adaptively manage the water holdings.
