Lake Macleod is the westernmost lake in Australia. It lies north of the small coastal city of Carnarvon, Western Australia, estimated population 8,816.[1]

History

Dirk Hartog, a Dutchman, made the first authenticated landing by a European along this coastline in 1616. Early explorers recorded phenomenal tidal ranges along this coast.

Description

Climatically, this part of Western Australia is greatly influenced by the north-flowing Western Australian Current that brings cool water northward from Antarctica, which is not conducive to producing inland precipitation. This cool offshore current, coupled with a very flat coastal plain, contributes to the near-desert-like conditions along the coastal region as evidenced by the brown landscape around the lake and the highly reflective salt beds within the lake. The low point in the lake appears to be near the northern end where the light blues indicate some standing water. Close inspection of the image discloses very faint lines at the southernmost end of Lake Macleod where large evaporation beds are used for the production of high-quality salt and gypsum.[2]

Environment

The lake is recognised as a DIWA wetland as it is an outstanding example of a major lake situated on the coast that is periodically inundated by freshwater[3]

Birds

Some 382  km2 of the permanent ponds in the north-western part of the lake have been identified by BirdLife International as an Important Bird Area (IBA) because they support fairy terns, over 1% of the world populations of red-necked stints, curlew sandpipers, banded stilts, red-necked avocets and red-capped plovers, as well as a population of dusky gerygones.[4] The northern ponds consist of intermittently flooded, brackish to hypersaline mudflats surrounding saline springs and permanent saline channels and lagoons. Large numbers of red knots, Australian pelicans, little black cormorants, black-tailed godwits and black-winged stilts have been recorded. A substantial population of canary white-eyes is present.[5]
