The Darling is a big river in Australia.
People have lived by the river for a very long time. They made stone fish traps. These are very old. 
Some boats used the river to carry wool. Now the river is in poor health. It can get very dry.
When it is dry, the water can get too warm. This can hurt the fish.
It is a famous and special place.
The Darling River is a famous waterway in Australia.
Indigenous people have lived here for a very long time. The Barkindji people call the river Baaka or Barka. They made stone fish traps in the water. These traps are over 40,000 years old. They are the oldest man-made things on Earth. 
In the past, paddle steamers moved wool along the river. Many towns sit along the banks. These include Bourke, Wilcannia, and Menindee.
Today, the river is in poor health. It suffers from drought and pollution. Sometimes the river barely flows at all. When it is dry, the water gets very warm. This can cause many fish to die. This happened in 2019 and 2023. The river needs good care to stay healthy for the future.
The Darling River is a very famous waterway in the Australian outback. It is the third-longest river in the country. When you add its many connected branches, it becomes the longest river system in Australia.
Many different rivers join together to make this huge system. The Darling officially begins where the Culgoa and Barwon rivers meet. Other rivers like the Bogan, Warrego, and Paroo also flow into it. These waters come from places like southern Queensland and northern New South Wales.
People have a very long history with this river. The Barkindji people call it Baaka or Barka. They have lived along these waters for tens of thousands of years. At Brewarrina, they built ancient fish traps out of rock. These traps are estimated to be more than 40,000 years old. They might be the oldest man-made structures on our planet. 
In the late 1800s, the river was a busy place for travel. Farmers used shallow-draft paddle steamers to move wool. They sent this wool from river ports like Bourke and Wilcannia. These boats traveled to railheads in South Australia. 
Right now, the river is facing some hard jobs. It is in poor health due to drought and pollution. In 2019, the river barely flowed at all. In 2023, many fish like Murray cod died because the water was too warm and lacked oxygen. 
The Darling River is a vital waterway in the Australian outback. It is the third-longest river in Australia. If you include its longest connected tributaries, it is the longest river system in the country.
The river follows a very winding course across the land. This meandering path is actually three times longer than the direct distance it travels. Much of the land the river flows through consists of flat plains. Because the land is so level, the river has a very low gradient. It only drops an average of 16 mm per kilometre. The river officially begins between Brewarrina and Bourke. This happens at the confluence, or meeting point, of the Culgoa and Barwon rivers. Many other rivers join the system, such as the Bogan, Warrego, and Paroo rivers.
Indigenous Australians have lived along the Darling River for tens of thousands of years. The Barkindji people refer to the river as the Baaka or Barka. At Brewarrina, they created ancient fish traps using rock formations. These traps are estimated to be more than 40,000 years old. This makes them potentially the oldest man-made structures on the planet. 
European exploration of the region began in the early 1800s. In 1828, explorers Charles Sturt and Hamilton Hume investigated the Macquarie River. In 1829, Sturt visited the upper Darling and named it after Sir Ralph Darling. This was the Governor of New South Wales at the time. Later, in 1835, Major Thomas Mitchell travelled part of the river. He correctly believed the river flowed into the Murray River. In 1856, the Blandowski Expedition travelled to the junction of the Darling and Murray rivers. They successfully collected 17,400 fish specimens for the National Museum.
During the late 19th century, the river was a major route for transportation. Pastoralists used shallow-draft paddle steamers to move wool. They sent goods from river ports like Bourke and Wilcannia to railheads in South Australia. Wentworth was even Australia's busiest inland port in the late 1880s. However, the importance of the river for transport has declined over the last century. Today, people use the Barrier Highway and the Broken Hill railway line to cross the river instead.
Currently, the Darling River is in poor health. It suffers from over-allocation of water for irrigation and pollution from pesticide runoff. The river also faces problems with high salt content and declining water quality. In 1992, a severe cyanobacterial bloom occurred along the river's length. This was a bloom of toxic algae that flourished due to the presence of phosphorus. Other factors included flow rates, temperature, and turbidity, which is the cloudiness of the water. 
Environmental changes have also impacted the local ecosystems. In 2008, the Federal government purchased Toorale Station for $23 million. This allowed the government to return environmental flows to the river. However, the Menindee Lakes Scheme has reduced the frequency of natural flooding. This has resulted in the destruction of 13,800 hectares of lignum and 8,700 hectares of Black box plants. In 2023, another major fish kill occurred at Menindee. Millions of fish, including Murray cod and golden perch, died due to high temperatures and low oxygen levels. The long-term health of the river depends on careful management.
