Here is a [url=http://www.youtube.com/watch?v=wWzZjUduuBw]link to a YouTube video[/url] (2:45) taken at the confluence of Kedron Brook and Cedar Creek at Bob Cassimatys Park Ferny Grove on 11 January 2011.
The same heavy rain that caused this local flooding devastated much of Brisbane and much of Queensland. Fortunately the upper Kedron Brook catchment is fairly compact and the water moves on pretty quickly.
