History
The sand dune system responsible for the formation of the estuary began about 7,000 years ago. At this time the coast section between Mandurah and Bunbury was an open rocky limestone shore. A dune system began to build on the shore forming a long barred estuarine lagoon between the current estuary as far north as Lake Preston and effectively separated the lagoon from the ocean.
About 4,500 years ago the dune system met up with the eastern shore of the estuary separating the lagoon into two sections. The northern portion filled with mud leaving the southern section as the estuary that exists today.
Construction of the 'Cut', which opens the estuary into the ocean opposite the Collie River mouth, commenced in February 1950.

Famous quotes containing the word history:
“If you look at history you’ll find that no state has been so plagued by its rulers as when power has fallen into the hands of some dabbler in philosophy or literary addict.”
—Desiderius Erasmus (c. 1466–1536)
“Whenever we read the obscene stories, the voluptuous debaucheries, the cruel and torturous executions, the unrelenting vindictiveness, with which more than half the Bible is filled, it would be more consistent that we called it the word of a demon than the Word of God. It is a history of wickedness that has served to corrupt and brutalize mankind.”
—Thomas Paine (1737–1809)
“Like their personal lives, women’s history is fragmented, interrupted; a shadow history of human beings whose existence has been shaped by the efforts and the demands of others.”
—Elizabeth Janeway (b. 1913)
