Daly
17.5 Overbank flood spilling

Supporting information

The volume of overbank flow from the river channel during the 2011–12 year cannot be quantified accurately due to a lack of available data.

Most streams in the upper reaches of the Daly region flow in confined channels; however, during periods of major flooding in the lower Daly River overbank flow inundates the floodplains. Given there were two periods of high flow in the lower Daly River during the 2011–12 year (see Water overview), the omission of this volume in the water account is likely to have a material impact on the water balance of the surface water store.
