Assessing estuary health

Our Healthy Estuaries WA program uses a range of indicators to assess the health of estuaries.
Last updated:

Assessments include understanding aspects of water quality, sediment qualityseagrassmacroalgae and phytoplankton, and catchment pressures such as river flows, land use and inputs.

Integrated assessments of estuary health provide an understanding of current condition as well as inform on the likely responses of estuaries to additional pressures (e.g. climate change or new development). 

We also model the impact of catchment land use change and nutrient export into our waterways.
