The Murray is a very long river.

It is in Australia. It is the longest river in that land.

The river starts in high mountains. Then it flows across flat plains. It flows through many lands. It even makes a border between two places.

Many animals live in the water. You might see a big fish called a Murray cod. There are also turtles and shrimp.

Trees called red gums grow by the water. These trees like to have lots of water. Sometimes the river floods and covers the land.

The river ends at the sea.

The Murray River is in southeastern Australia.

It is the longest river in Australia. The river starts in the Australian Alps. From there, it flows across flat plains. It winds its way toward the sea.

The river helps mark borders between states. It forms the border between New South Wales and Victoria. In some parts, it also marks the border for South Australia. Many rivers flow into the Murray. These are called tributaries. The Darling River is one of these big tributaries. Together, these rivers form the Murray–Darling basin. This basin covers about one-seventh of Australia.

Many animals live in the water. You might see the Murray cod. This is a famous fish. You might also find turtles, shrimp, and platypus. Red gum trees grow along the banks.

The Murray River is a huge and important part of southeastern Australia.

Murray River at Boundary Bend.jpg

It is the longest river in the whole country. The river begins high up in the Australian Alps. From there, it winds across flat inland plains. It travels northwest and then turns south toward the sea. This river is part of the Murray–Darling basin. This large area covers about one-seventh of Australia. Many other big rivers, like the Darling and Murrumbidgee, flow into it.

Water moves through the river in many different ways. The river has many tributaries that bring extra water into the main stream. Some parts of the river are very narrow, like the Barmah Choke. These narrow spots can limit how much water flows through. The river also uses locks and weirs to manage the water.

In some areas, the water flows into a large lake called Lake Alexandrina. Finally, the river reaches the Murray Mouth.

Here, the fresh water meets the Southern Ocean. To keep the mouth open, machines move sand away so it does not clog up.

Long ago, the river looked very different. Between 2.5 and 0.5 million years ago, the river ended in a massive lake. This was called Lake Bungunnia. It was a huge freshwater lake that covered a very large area.

About 600,000 years ago, this lake finally drained away. Much later, a movement in the earth called the Cadell Fault changed things. This fault happened about 25,000 years ago. It changed the path of the water. This change helped create the famous forests of river red gum trees.

There are many interesting facts about the river's size and its borders. The river is 2,508 kilometers long. It is also a border between different states. The line between New South Wales and Victoria sits at the top of the Victorian bank. This means the water and the riverbed belong to New South Wales. Some towns sit right along the water. Albury-Wodonga has 89,007 people. Mildura and Merbein has 35,451 people.

Other places, like Murray Bridge, have 16,804 people. The river can even dry up completely during very bad droughts.

Nature and people are closely linked to this river. Many animals call the Murray home. You can find the famous Murray cod and golden perch in the water.

You might also see platypus or water rats near the banks. Aboriginal Australians have important stories about the river. Some say the Great Ancestor, Ngurunderi, created the river. They believe he was chasing a large fish called Pondi. The river's paths were made by the chase. The river is a vital place for both animals and people today.

The Murray River is the longest river in Australia, stretching across 2,508 kilometers.

It is a vital part of the Murray–Darling basin. This basin covers about one-seventh of the Australian continent. The river system is essential for the country's most important irrigated region. It drains the western side of the Australian Alps. From there, it meanders across inland plains toward the sea.

Water flows through a complex network of tributaries and channels. The Murray receives water from several large rivers. These include the Murrumbidgee, Darling, Lachlan, Warrego, and Paroo Rivers. The confluence of these rivers creates a massive drainage system. The river's path is not always straight. At Morgan, it turns south toward its final destination. It reaches the eastern edge of Lake Alexandrina. This lake has water that fluctuates in salinity, or salt levels. The water then moves through channels near Hindmarsh and Mundoo Islands. Finally, it empties into Encounter Bay through the Murray Mouth.

Geological changes have shaped the river over millions of years. Between 2.5 and 0.5 million years ago, the river ended in Lake Bungunnia. This was a massive freshwater lake. It reached as far north as the Menindee Lakes. The lake drained approximately 600,000 years ago. This event likely marked the end of a wet phase. It led to the arid conditions seen in the basin today. Deep clays from this lake are still visible in cliffs near Chowilla.

Another major change occurred about 25,000 years ago due to the Cadell Fault. This fault is a displacement in the earth's crust. It raised an eastern edge, creating a north-south line. This movement diverted the river's path. The Murray began flowing around the fault. This created the Edward River channel. It also created "The Barmah Choke" and "The Narrows." These are places where the river channel is unusually narrow. These conditions allow the river to flood low-lying country regularly. This flooding created the famous Barmah river red gum forests.

Human history and legal boundaries are also tied to the river. The river forms a border between New South Wales and Victoria. However, the border is at the top of the Victorian bank. This means the water and the riverbed belong to New South Wales. This specific definition caused a long-running boundary dispute in the 1840s. A survey error of 3.72 kilometers led to this confusion. West of 141°E, the border moves to the middle of the river. This separates Victoria and South Australia.

Many major settlements rely on the river for life. Albury-Wodonga is a large center with 89,007 people. Other notable towns include Mildura and Merbein, which has 35,451 residents. Murray Bridge has a population of 16,804.

Historically, paddle steamers were used for commerce. These vessels moved goods between Adelaide and river settlements. Today, the river is highly regulated. This regulation helps manage water for irrigation and towns. However, it also impacts the natural flow of the system.

The river supports a wide variety of native wildlife. You can find the Murray cod and golden perch in its waters.

Other animals include the Murray short-necked turtle and the platypus. The Murray crayfish is an endangered species. Scientists have worked to increase its numbers. However, the river faces challenges from extreme droughts. The river has dried up completely three times since official records began. At the Murray Mouth, dredging machines must work constantly. They move sand to prevent the mouth from silting up. This keeps the connection to the Southern Ocean open.
