I am sure previously we have enough wetlands around the reservoir to breed predators, but overtime we lose it to construction activities (Archipelago for example)

Midge swarms are more common in urbanised reservoirs as these ecosystems may not be
adequately balanced or established, and there may not be sufficient predators to feed on
and control the midge population. This is unlike more natural catchments such as MacRitchie
Reservoir, where the existence of a stable and established ecosystem enables the midges’
predators to flourish and keep the population of the midges in check.
