The Myall Lakes comprise four connected basins: Bombah Broadwater, Two Mile Lake, Boolambayte Lake, and Myall Lake, and is the biggest lagoon system in New South Wales, Australia. Bombah Broadwater receives most of the catchment discharge and is weakly connected to the ocean via Myall River. Myall Lake is the ultimate backwater, receiving very little catchment discharge and having a constricted, shallow connection to Boolambayte Lake which, in turn, connects to Bombah Broadwater via the narrow Two Mile Lake. Infrequent flood events and droughts cause large salinity changes in Bombah Broadwater but Myall Lake remains stable. Plankton assemblages vary in Bombah Broadwater in ways that are related to salinity. In Myall Lake chlorophyll is stable and low. Meadows of charophytes and Najas marina are widespread in Myall Lake and these macrophytes are associated with high water clarity and a thick layer of ammonium-rich gyttja. Rising sea level, associated with climate change, has the potential to disrupt the hydrologic stability of Myall Lake and induce an ecological change of state.
