Tasmania is covered with a network of rivers and lake systems:
- In the south, the Derwent flows from the Central Highlands past Hobart, to the sea at Storm Bay.
- 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.
- 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.
- Flowing from the north-east, the South Esk, the State's longest river, joins the North Esk at Launceston to create the Tamar.
