Major flooding in Lismore: Friday 2nd February 2001
by Michael Bath including photos by Dave Ellem

The Wilsons River in Lismore peaked at 10.42m [AHD] at around 5.30pm on 2nd February after 48 hours of torrential rain, including 200 to 250mm in 12 hours from 9am Thursday. For comparison, floods measured with the new Australian Height Datum calculation are about 80cm lower than the old flood scale used in Lismore. So this flood was comparable with a flood of 11.2 metres on the old scale as most people of the Lismore region would recognise it.

The following pictures were taken around the CBD of Lismore from about 4.30pm on the 2nd February as Dave Ellem and I walked around town. The flood basin behind the riverbank was still filling up with water at this stage. Although shops closer to the river were already experiencing the peak of 10.42 metres, in the basin it was several metres lower. It rose 60 cm while we walked around the town! There are some similar images as Dave and I took photos at the same locations.
