The Willaura Salinity Province is a low-lying basalt (older phase volcanics) flood plain, which lies between the Grampians Ranges to the west and the Hopkins River to the east. Multiple drainage basins fed by runoff from the Grampians Ranges have developed on the basalt surface, many of which are naturally saline through high watertables and restricted outflow. Many have an aeolian lunette on the eastern shoreline which is also indicative of ephemeral and sometimes saline lakes. The Province is a complex landscape of local to intermediate Groundwater Flow Systems with a large presence of primary salinity features.
Management options are limited to the broad-scale goal of improving plant water use across productive areas and by protecting low lying, naturally waterlogged and saline areas from damage, especially at their margins during wetter periods.
