Geography
The Yarra River has a detailed and complex geological history, see "Geology". It was utilised and managed sustainably by the Wurundjeri for around 40,000 years, however since the European settlement and use of the river in the mid-19th century, its geography has changed substantially reflecting the unsustainable use of the river and surrounding resources. The river is fed by a number of small unnamed creeks and streams in the Yarra Ranges as well as 49 named tributaries, most of which are creeks. The river's lower reaches travel through central Melbourne. It is approximately 242 kilometres (150 mi) in length, with a mean annual flow of 718 gigalitres (2.54×1010 cu ft), which is roughly 50% its original flow prior to damming. It is the most westerly snow fed river in Australia. The total catchment area is approximately 4,000 square kilometres (1,500 sq mi).

Famous quotes containing the word geography:
“Ktaadn, near which we were to pass the next day, is said to mean “Highest Land.” So much geography is there in their names.”
—Henry David Thoreau (1817–1862)
“The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.”
—Willard Van Orman Quine (b. 1908)
“At present cats have more purchasing power and influence than the poor of this planet. Accidents of geography and colonial history should no longer determine who gets the fish.”
—Derek Wall (b. 1965)
