Stokes Inlet


Stokes Inlet is an inlet in the Goldfields-Esperance region of Western Australia.
The inlet is situated from Esperance in Stokes National Park and is set is a large river valley with permanent deep water and high dunes located on either side. Thick bushland and paperbark trees surround the inlet and grow down to the waters edge. It is in a largely unmodified condition.
The inlet functions primarily as a result of wave energy and is a wave dominated estuary.

Geography

The inlet is managed by the Department of Environment and Conservation with a catchment that extends over inland and is fed by two main rivers: The Young and Lort River.
The inlet itself is long and wide with an area of and receives an annual flow of 5 million cubic metres.
The central basin has an area of with intertidal flats having an area of approximately.
The mouth of the river is in the middle of Dunster Castle Bay, it is closed by a sandbar that cuts the estuary off from the sea and only opens every few years. As a result, the salinity and water level fluctuate greatly dependent upon the amount of evaporation and river flow.

Flora

The aquatic flora of the estuary are dominated by the small green algae Polyphysa peniculus the stonewort Lamprothamnium papulosum and the seagrass Ruppia megacarpa.
The waterbody of the inlet is fringed with Salt Water Paperbarks with sedges and samphire common along the sandy sections.

Fauna

Marine species flourish at times when the bar is open such blue manna crabs, juvenile prawns, cockles and mussels have all been identified in the inlet.
Many fish species inhabit the estuary such as the common minnow, hardyheads, gobies and larger species such as Black Bream and Sea Mullet.
