In 2017-18 the Fitzroy Basin received an overall C grade for aquatic ecosystem health, which is consistent with the previous year. Fitzroy catchment, Upper Dawson, Comet, Lower Isaac and the Estuary were awarded B grades, with all other catchments awarded C grades. Ecosystem health has remained stable overall in 2017-18 compared to 2016-17. The condition of Comet, Fitzroy, Lower Dawson and Lower Isaac catchments and Estuary Zone improved. There were slight decreases overall for ecosystem health for the waterways of Callide, Connors, Mackenzie, Nogoa, Theresa, Upper Dawson and Upper Isaac. Lack of ecology data across the Basin has been identified as a contributing factor to changes in results each year.
