Photographer's Note

In January 1974, excessive rain from ex tropical Cyclone Wanda caused Kedron Brook to break its banks. The red line on the wooden marker indicates the water height. It was matched in the February 2022 floods, possibly even exceeded! Fortunately the Brisbane River stayed below 4 metres this year. The 1974 flood height of the Brisbane river was 5.5 metres. It was 4.5 metres in 2011. Repairs of children's playground equipment and bbq facilities in the bg are ongoing. The marker was installed on the 25th anniversary of the 1974 flood. (1999).

"In the catchments of the Brisbane Metropolitan creeks, heavy rain commenced about 2am on Friday 25 January and continued until about 2pm the same day. During that 12 hour period falls ranged from 197mm at the Bureau to 236mm at Enoggera Reservoir and 280mm at Mount Nebo. The rain then eased but between 6pm Friday and 3am Saturday 26)January, very intense rainfall was experienced for the second time, with 151mm being recorded at the Bureau, including 82mm between 9pm and midnight. In this latter 3 hour period 202mm fell at Enoggera Reservoir."

Rainfall at Upper Kedron in February 2022 over 3 days was 222mm, 228 mm & 222mm. Many Brisbane suburbs had over 1,000 mm during this period, with major flooding downstream at 4 metres near Toombul Shoppingtown, which is closed for 6 months & might never reopen. Here's a video of Kedron Brook in full flood in February 2022:
