Estuaries Across the Region
The environmental health of the Wet Tropics estuaries is assessed on water quality, habitat and hydrology, and fish. For 2018-19 scores and grades are provided where data is available, with further development required for the fish index.
The eight estuaries included in the Wet Tropics Report Card region are Daintree, Dickson Inlet, Barron, Trinity Inlet, Russell-Mulgrave, Johnstone, Moresby and Hinchinbrook Channel.
For 2018-19 most estuaries were graded good. The exceptions were the Barron and Trinity Inlet, which were graded 'moderate'.
For estuaries across the Wet Tropics the period of August to November was very dry with low monthly rainfall compared to average monthly rainfall. This contrasted with the heavy rainfall events that commenced in December, which were very much above average. The effect of the rainfall pattern was evident for some water quality indicators, particularly in the Barron which showed strong seasonal change.
