Dickson Inlet

The area of the Dickson Inlet estuary reporting zone can be defined by the pre-cleared extent of mangrove and saltmarsh remnant vegetation which is characterised by species that require periodic inundation of sea water.

This area extends approximately 6.5 km north-east and 3.5 km south of the inlet mouth along the coastline and extends approximately 3.3 km inland. The area includes several coastal tributaries that drain into the Inlet.

Land use within the Dickson Inlet estuary area is dominated by residential and tourism service developments. There is a marina located within the Inlet. The town of Port Douglas (population 3,205) is located within the estuary area and is a major tourism centre which attracts many national and international visitors each year

Water quality

Hover over each segment for indicator scores and data confidence.

A water quality overall score and grade cannot be provided for Dickson Inlet in 2014/15 due to insufficient data. Estuarine water quality monitoring will be commencing in Dickson Inlet and will be available for future report cards.

Habitat and hydrology

Hover over each segment for indicator scores and data confidence.

The overall habitat and hydrology grade for Dickson Inlet could not be determined due to insufficient data. The development of the flow and fish barrier indicators will provide sufficient data for habitat and hydrology to be reported for Dickson Inlet estuary in future report cards.

The mangrove and saltmarsh extent scored 80.7 (moderate) with 7.9 per cent loss from pre-clear to 2013. The riparian extent scored 67.0 (Moderate) with 24.9 per cent loss from pre-clear to 2013. These results reflect the surrounding development which has occurred along the fringe of the estuary area.

Estuary riparian extent and mangrove and saltmarsh extent are updated every four years and the figures in the pilot report card are the most current. The data for both are due to be updated in 2017/18.

The methods for the flow and fish barrier indicators are currently under development and will be available for future report cards.

Fish
