The Singapore River is a famous waterway in the country of Singapore. 


Long ago, the river was a very busy place for trade. Many boats like lighters moved goods along the water. In 1977, there were about 750 of these boats in the area. However, the river became very dirty and polluted. Waste from pig and duck farms flowed into the water. Garbage and sewage from industries also made the river smell bad. Even street hawkers and vegetable sellers added waste to the banks. Oil spills from the many boats made the problem even worse.
History tells us that a prince named Sang Nila Utama visited this area. In the year 1299, he landed at the river's mouth. This place was once an ancient fishing village called Temasek. The prince saw a strange animal with a red body. He thought it was a lion and renamed the area Singapura. 
In 1977, Prime Minister Lee called for a massive clean-up. This was a very big job that cost $300 million. The government moved about 4,000 squatters to new public housing. They also moved hawkers to special food centres. Workers dredged the foul-smelling mud from the river bottom. They cleared away all the rubbish and debris. Since 2008, the river has been fresh water. This happened after the Marina Barrage dam was finished. Now, the river is part of the Marina Reservoir.
Today, the river looks very different from the past. It is clean enough for animals like otters and monitor lizards. Instead of heavy trade, the river is now for tourism. You can ride a water taxi across the water. Many beautiful bridges cross the river, like the Helix Bridge from 2010. 
The Singapore River is a vital waterway located in the southern part of Singapore. 

The planning area is surrounded by several distinct districts. To the north lie the River Valley and Museum areas. The west is bordered by Tanglin and Bukit Merah. To the south sits Outram, while the Downtown Core lies to the east. The river's immediate surroundings are divided into three specific sections known as wharfs or quays. Robertson Quay is the largest and is located furthest upstream. Following this are Clarke Quay and Boat Quay. 
Historically, the river's mouth was the site of an ancient fishing village called Temasek. In 1299, a prince from Srivijaya named Sang Nila Utama landed at the estuary, known as Kuala Temasek. According to the Sejarah Melayu, or Malay Annals, the prince encountered a strange beast. He described a creature with a red body, a black head, and a white breast. He believed the animal was a lion. Because of this, he renamed the area Singapura, which means "Lion City" in Sanskrit. 
From 1819, the river became a center for rapid urbanization and expanding trade. This growth led to heavy traffic and severe water pollution. Many industries located along the banks disposed of garbage, sewage, and other by-products into the water. Pollution also came from pig and duck farms, street hawkers, and vegetable wholesalers. Riverine activities like boat building, repairs, and transport added to the mess. In 1977, there were roughly 750 lighters plying the Singapore River and Kallang Basin. These boats caused oil spills and released wastewater, further damaging the ecosystem.
In 1977, Prime Minister Lee called for a massive clean-up of the Singapore and Kallang Rivers. This project was a major undertaking that cost the government $300 million. The government had to relocate about 4,000 squatters to public housing. Street hawkers and vegetable sellers were also moved to established hawker centres to stop waste from flowing into the river. Workers dredged foul-smelling mud from the river banks and the bottom. They cleared away all debris and rubbish to restore the water. This effort fundamentally changed the river's health.
Since 2008, the Singapore River has been a freshwater river. This change occurred after the completion of the Marina Barrage at Marina South. The damming of the river at its outlet created the Marina Reservoir. This process also changed the river's geography. Originally, the mouth emptied into the Singapore Straits and southern islands. Now, it empties into the partially enclosed Marina Bay. The river's economic purpose has also shifted. It no longer serves as a primary hub for trade. Instead, it supports tourism and the aesthetics of the commercial zone. 
Today, the river is a clean environment where monitor lizards and otters have re-emerged. Visitors can traverse the water using water taxis. The area is also home to many bridges and artistic sculptures. Between 1819 and 2015, 14 bridges were built across the river, though some sources suggest 17 including the reservoir area. Notable bridges include the historic Elgin Bridge and the modern Helix Bridge, built in 2010. Along the banks, sculptures like "First Generation" and "Fishing at Singapore River" depict early local life. These landmarks connect the modern city to its hardworking past.
