[1] The Kallang Basin is a popular location for water sports, in particular, kayaking and dragon boating.
Numerous islands also existed in the Kallang Basin, including Pulau Mengalu which was located at where modern-day Bendemeer MRT station is.
At its greatest extent, the Kallang Basin once extended as far north as today's Bendemeer Road.
According to the Cho Clan Archives, Raffles ordered his ship's carpenter, Chow Ah Chi, to lead the way in posting the British East India Company flag on mainland Singapore and he supposedly landed at the mouth of the Rochor River in Kallang.
[5][6] This was possible because the Kallang Basin was directly connected to the open sea at the time of Raffles' founding of modern Singapore.
