Groundwater Management Unit

Groundwater Management Unit: King Lake
Introduction


The groundwater resource characteristics for the King Lake groundwater managment unit are presented below. This includes technical detail on aquifer properties and water level change for key monitoring bores.
What is the character of King Lake's groundwater resource?
Vital Statistics:
| Area | 90 km2 |
|---|---|
| Total Water Allocated | 1,906 ML/yr |
| Total Water Used | 503 ML/yr |
| Average Salinity | 300 mg/L |
| Sustainable Yield | 3,800 ML/yr |
| Depth to top of aquifer | 20 m |
Aquifer Description:
Unconfined fractured rock system within the Devonian siltstones and sandstones.
Method used for determining sustainable yield:
Due to the lack of hydrogeological data in the Kinglake area, the PAV has been determined using the rainfall recharge calculation (4,000 ML/year) minus the calculated discharge to streams (175 ML/year). The resultant PAV for the Kinglake zone is 3,830 ML/year.
Assumptions used for allocating development categories:
Categorisation is based on the allocation and use figures obtained from Southern Rural Water. The resulting categorisations indicate that the Kinglake GMU is of low development status, and low use. There is opportunity within this GMU for development to occur.
Are groundwater levels changing?
Technical information on the key groundwater bores and monitoring stations is presented below, including hydrographs where available. Link to a discussion on groundwater levels and trends at a State level as it relates to dryland salinity.
There are no bore monitoring stations recorded in this area for this assessment
