Rivers of Tasmania facts for kids

Kids Encyclopedia Facts

This page discusses the rivers and hydrography of the state of Tasmania, Australia.

In the geography of Tasmania, the state is covered with a network of rivers and lake systems. As an island, all rivers eventually empty into the waters that surround Tasmania. There are four main river systems:

  1. In the south, the Derwent flows from the Central Highlands past Hobart, to the sea at Storm Bay;
  2. In the west, the Gordon River takes the waters of Lake Gordon and Lake Pedder and is joined by the Franklin River before flowing into Macquarie Harbour;
  3. Flowing eastwards and to the south, the Huon River has its headwaters at Scotts Peak Dam on Lake Pedder, and reaches the sea in D'Entrecasteaux Channel; and
  4. Flowing from the north-east, the South Esk, the state's longest river, joins the North Esk at Launceston to create the Tamar.

Compared to the rest of Australia, Tasmania has a very high proportion of wild or undisturbed rivers.
