The Lexton Salinity Province is a small province of less than 10,000 ha that makes up part of the headwaters of the Loddon River catchment. Approximately 2% of the Province is salt effected land, which contributes a high salt load to the river. The province features local to intermediate scale Groundwater Flow Systems in weathered, fractured Palaeozoic rocks (including granite), which dominate the landscape with some rocky ridges extending to the upland alluvial plains. Some salinity is expressed as ‘break-of-slope’, but most is mapped along drainage lines, many of which are deeply eroded. |
