As is the case for most other reservoirs in Singapore, swimming is currently illegal in the lake, although this may change in line with the Singapore government's liberalisation of the use of bodies of water in the republic. Fishing is now allowed in some designated spots around the lake where only artificial baits can be used for fishing. However, the water is noted to be green in colour during dry weather and a murky brown after a downpour, the likely result of runoff from its urban catchment area.
