The Dinner Hill subarea allocation statement was released in June 2019.
The statement contains:
- allocation limits, which define how much water is available from the Leederville-Parmelia aquifer in Dinner Hill
- licensing policies for how groundwater resources will be allocated and managed
- objectives, strategies and performance indicators for monitoring and measuring the effectiveness of the statement
- how we will implement the statement and evaluate information.
Water allocation planning in the Dinner Hill subarea
Dinner Hill is a subarea of the Jurien groundwater area. The department reviewed the water supply potential of this subarea as part of the Midlands Groundwater and Land Assessment. The assessment was part of the Water for Food program, a State Government initiative to realise Western Australia's irrigated agriculture potential.
In May 2019 we released the Dinner Hill subarea allocation statement, which supports the Jurien groundwater allocation plan. The statement is to be read in conjunction with the Jurien groundwater allocation plan.
- an increased allocation limit for the Leederville–Parmelia aquifer in Dinner Hill
- licensing objectives and policies specific to Dinner Hill
- monitoring and future resource investigations.
Dinner Hill subarea
The Dinner Hill subarea is 150 kilometres north of Perth and covers 1,850 km2 within the Jurien groundwater area. Along with the Gingin and Arrowsmith groundwater areas, the Jurien groundwater area is part of the Northern Perth Basin.
The groundwater resource covered under the statement is the Leederville–Parmelia aquifer. For management purposes, it is managed under one subarea. The Leederville–Parmelia aquifer is the most prospective aquifer for large volume water licences in Dinner Hill. For a sustainable resource, the best areas to abstract more groundwater from the Leederville–Parmelia aquifer are the northern parts and the western parts of Dinner Hill.
