The Singapore River is a canal in Singapore with great historical importance. (Despite its name, Singapore River is not a river because it lacks the three courses of a river) It flows from the Central Area, which lies in the Central Region in the southern part of Singapore before emptying into the ocean. The immediate upper watershed of the Singapore River is known as the Singapore River Planning Area, although the northernmost part of the watershed becomes River Valley. As the Central Area is treated as a central business district, nearly all land surrounding it is commercial. It is one of about 90 rivers in Singapore and its islands. It is the place where Raffles made the 1st trading port in Singapore. The Singapore River is the most famous river in Singapore.[Source]
