It is not uncommon to see next to rivers that flood frequently, posts or markers indicating flood heights in the past.

This is a flood marker with a difference. A piece of timber lodged in a tree next to the Bremer River that indicates the height of the flood in January 2011. This timber is about 19 m above the river. Viewed from normal river level in a kayak, it provides a striking sense of the height of the flood and enormity of water that is missed when viewed from above.
