Calamvale Creek during flood and drought
Calamvale Creek relies on stormwater runoff to top it up. So it is prone to flooding during heavy storms and drying up after long periods of no rain.
Here are photos of both occurrences.
The photo above shows the boardwalk near Gowan Road smashed shortly after construction when a strong storm knocked trees on to it.

The parkland surrounding the creek is a shallow bowl designed to hold and retard floodwaters so they won't flood nearby houses. The photo above shows the park along Matilda Way. Occasionally the waters have briefly reached road level, but they drop quickly when the rain eases.
The wooden bridge over the creek was temporarily cut off after the January 25, 2007 flood, although it was passable for those who didn't mind getting their feet wet.

Large parts of the creek had no surface moisture. Only the deeper water zones functioned as refuges for organisms that were later able to recolonize the wetlands and creek.
