Your Question

There are at least 2 rivers in SW Singapore (Jurong area) that appear to be known by different names, depending on which resources one checks. Eg.-- Sungei Jurong (OneMap.sg) vs. Sungei Bajau Kanan (StreetDirectory.com)-- Sungei Lanchar (OneMap.sg) vs. Sungei Bajau (StreetDirectory.com)Sg Jurong /Sg Bajau Kanan flows southwards from Jurong Lake (near Jurong Country Club) to the sea, running parallel to Penjuru Rd, & passing by Jurong Port along the way.Sg Lanchar / Sg Bajau flows westwards (then southwards) from Jurong Lake, passing by Jurong Central Park, Jurong Hill/Bird Park & NatSteel Holdings before reaching the sea.a) Sg Jurong, Sg Lanchar & Sg Bajau are mentioned in archived local newspapers at NewspaperSg.b) Sg Jurong, Sg Bajau Kanan, Sg Lanchar & Sg Bajau are all listed in Cartographic & Architectural Records Database Singapore (CARDS), although the very faded maps are difficult to decipher.c) Sg Jurong & Sg Bajau are listed in SgWiki’s list of rivers.d) Jurong River (synonym: Sg Jurong) is listed in PUB’s public list of catchment rivers. I assume Sg Lanchar/Bajau currently does not serve as a catchment waterway.e) The above-mentioned river names seem to be used interchangeably by laymen.1) May I know which are the correct/official river names, or if the 2 mentioned rivers indeed have 2 names each ? If the latter, what is the historical background that led to this ?2) Is there any definitive & current list/reference that contains the names of all the rivers found in Singapore ?

Thank you for using Reference Point

OneMap.sg, being owned and operated by the Singapore Government (see website), would be considered the 'government' map. Streetdirectory.com on the other hand is a private entity that operates online maps for several cities in the region.

Sungei Jurong aka Jurong River is a prominent feature of the southwestern part of Singapore with a long history and appears on the maps of Singapore under this name. Sungei Lanchar on the other hand is a smaller and less well-known stream/river just west of Jurong River. It appears in the published maps as Sungei Lanchar. In the 1961 1:25,000 map, only the mouth of the sungei is indicated on the map. The rear of Sungei Lanchar in that map is marked as an extensive area of swamp stretching eastwards to Jurong River. The recent street directories also mark it as Sungei Lanchar.

For Sungei Bajau, it is only mentioned in the pre-War newspapers twice - once in a smuggling case that does not give any locating information for it and the second time in a series of advertisements that places the sungei in Kranji. The Geology of Singapore (1976 & 2009 editions) show Sungei Bajau to be between Poyan and Tengeh Reservoirs. In OneMap, it is shown as being part of Poyan Reservoir. This tallies with the maps in the National Archives' a2o index which seem to indicate that Sungei Bajau is somewhere in the Kranji-Choa Chu Kang area and drains into the Straits of Johor. You may wish to visit the National Archives to consult the maps in order to confirm this.

Singapore's waterways are mostly maintained by PUB. It would seem likely that they would have the most complete listing of rivers, streams, canals and drains as virtually all are part of Singapore's water catchment and/or drainage system. However, we are not aware of them having published any comprehensive map or listing.
