# River Murray flood mapping, South Australia

The Department for Environment and Water modelled how far the River Murray spreads in South Australia at ten flows measured at the border, from 100 to 341 gigalitres a day, to help with flood preparedness. Each flow is its own layer here, beside the mapped extent of the 2022 to 2023 flood.
