After rain rivers rise.
Sometimes it might be by a few inches, but at others, rivers will rise by feet.
It is not unusual along the south coast rainforest escarpments of New South Wales for a storm to dump a few inches of rain. Every so often a south coast low pressure system brings 10 to 12 inches of rain in a 24 hour period. Rivers swell, bursting their banks, dragging vulnerable trees and branches downstream.
Sometimes, flood waters will seek an alternate course creating islands, and when the water recedes billabongs are left behind.
