Northern catchments
The northern catchments of the Murray-Darling Basin are shown in the unshaded area of the map below. In comparison to the southern catchments of the Basin, rivers in the northern catchments are less regulated and have extremely variable flows. Most floods in the northern catchments take place as a result of summer rainfall. At high flows, water spreads out over a vast floodplain and a significant amount of water does not return to the rivers. Periods of zero flow in the northern catchments can last months or even years.
