This 1913 map clearly shows the landscape of the Kallang Basin before major reclamation works began for Kallang Aerodrome in the 1930s. In the past, the three rivers: the Rochor, Kallang and Geylang Rivers, supported a number of
riverine communities. Take note that Kampongs Rokok, Laut and Kallang no longer exist.
