Groundwater Investigations To Support Irrigated Agriculture At La Grange, Western Australia: 2013–18 Results, Robert J. Paul, Gregory Paul Raper, Richard J. George Dr, Nicholas J. Wright, Adam M. Lillicrap, Peter S. Gardiner

Resource management technical reports

The Broome Sandstone aquifer is the main aquifer and groundwater resource in the La Grange area, near Broome in the West Kimberley, Western Australia. Land use is dominated by cattle grazing on pastoral stations, dispersed mining and tourism. Irrigated agriculture has developed at a small scale, with about 470 hectares under cultivation in 2014. Groundwater abstraction is licensed under the La Grange groundwater allocation plan (Department of Water 2010) and managed by the Department of Water and Environmental Regulation. The La Grange groundwater allocation area is split into the La Grange North subarea and La Grange South subarea, with groundwater …


Groundwater Chemistry And Salinity Processes In The Myalup Region, Adam M. Lillicrap, Richard J. George Dr Dec 2019

Groundwater Chemistry And Salinity Processes In The Myalup Region, Adam M. Lillicrap, Richard J. George Dr

Resource management technical reports

The Myalup region, which incorporates the Myalup Irrigated Agriculture Precinct (MIAP), is located about 100 kilometres south of Perth between the southern end of Lake Clifton and the northern tip of the Leschenault Inlet. It covers 17 800 hectares, with about 2100ha being irrigated. The precinct produces mainly carrots, onions, potatoes and leafy vegetables. In 2016–17, the total value of agricultural production for the MIAP, including on-farm processing and packaging, was more than $120 million.

Irrigation water is mainly from the surficial Myalup aquifer, with limited abstraction from the underlying Leederville aquifer. Average annual rainfall is about 800 millimetres, but …


Crop And Climate Suitability For Irrigated Agriculture In The Midlands Area Of Western Australia, 2nd Edition, Leon Van Wyk Jul 2019

Crop And Climate Suitability For Irrigated Agriculture In The Midlands Area Of Western Australia, 2nd Edition, Leon Van Wyk

Resource management technical reports

The Midlands groundwater and land assessment is a $4.7 million Water for Food project. Its aim is to confirm groundwater availability at one or more focus areas that may form precincts of 2000–3000 hectares suitable for intensive irrigated horticulture. This report forms part of this project.

Firstly, this report describes the climate of the Midlands study area and highlights the subtle differences between the two selected focus areas, Irwin and Dinner Hill. It discusses the importance of climate in determining crop suitability. We also investigated the following additional factors that determine crop suitability: water quality, water quantity, land capability (soils) …


Soil Capability Assessment For Expanding Irrigated Agriculture In The Dinner Hill Focus Area, Midlands, Western Australia, Edward Arnold Griffin, Angela Stuart-Street, Leon Van Wyk, Peter Tille Jun 2019

Soil Capability Assessment For Expanding Irrigated Agriculture In The Dinner Hill Focus Area, Midlands, Western Australia, Edward Arnold Griffin, Angela Stuart-Street, Leon Van Wyk, Peter Tille

Resource management technical reports

The Midlands groundwater and land assessment is a $4.7 million Water for Food project using Royalties for Regions funding. It is seeking to confirm groundwater availability in focus areas that may form precincts of 2000–3000ha suitable for intensive irrigated horticulture. The Dinner Hill focus area is one of these.

The Dinner Hill focus area covers about 50 200ha to the north-west of Moora and north of Dandaragan, in the Midlands area of Western Australia. This report provides details of the soil-landscapes, land capability and land management units for the Dinner Hill focus area.

We reviewed existing soil-landscape mapping for the …


Soil Capability Assessment For Expanding Irrigated Agriculture In The Irwin Focus Area And Surrounding Lands, Edward (Ted) Arnold Griffin, Angela Stuart-Street, Peter Tille May 2019

Soil Capability Assessment For Expanding Irrigated Agriculture In The Irwin Focus Area And Surrounding Lands, Edward (Ted) Arnold Griffin, Angela Stuart-Street, Peter Tille

Resource management technical reports

The Midlands groundwater and land assessment is a $4.7 million Water for Food project using Royalties for Regions funding. It is seeking to confirm groundwater availability in focus areas that may form precincts of 2000–3000ha suitable for intensive irrigated horticulture. Irwin is one of these.

The Department of Water identified the Irwin focus area for investigation for irrigated agriculture potential. It covers almost 7000ha to the east of Dongara in the Mid West region of Western Australia.

This report provides the land assessment for the Irwin area. We expanded the investigation to include land outside of the focus area because …


Pindan Soils In The La Grange Area, West Kimberley: Land Capability Assessment For Irrigated Agriculture, 2nd Edition, Henry Smolinski, Paul Galloway, Justin Laycock Feb 2019

Pindan Soils In The La Grange Area, West Kimberley: Land Capability Assessment For Irrigated Agriculture, 2nd Edition, Henry Smolinski, Paul Galloway, Justin Laycock

Resource management technical reports

This report identifies areas of Pindan country along the Great Northern Highway, south of Broome from Roebuck to Mandora, which have high potential for irrigated agriculture. The area contains significant reserves of potable groundwater defined by the La Grange groundwater allocation area, which is based on the surficial Broome Sandstone aquifer.

Over the past 30 years, several small- to medium-scale irrigation developments have been successfully established in the region. The water opportunities project aims to identify and quantify the land and water resources of the region to ensure any future expansion of irrigated agriculture is sustainable and will not have …


Investigations Of The Potential For Irrigated Agriculture On The Bonaparte Plains: Bore Completion Report, 2nd Edition, D L. Bennett Feb 2019

Investigations Of The Potential For Irrigated Agriculture On The Bonaparte Plains: Bore Completion Report, 2nd Edition, D L. Bennett

Resource management technical reports

Drilling programs were undertaken in 2013 and 2016 by the former Department of Agriculture and Food, Western Australia and in 2017 by DPIRD, at 10 sites in the Bonaparte Plains area, north of Kununurra in the East Kimberley region of Western Australia (WA).

These drilling programs were a component of resource availability and risk investigations conducted to determine the potential for developing irrigated agriculture on 30 000 hectares of Cockatoo Sands — free-draining loamy soils that have the potential to support crops in the wet and dry seasons. There was limited hydrogeological information available at a suitable scale for the …


Investigations Of The Potential For Irrigated Agriculture On The Bonaparte Plains: Land Capability Assessment Report, Henry Smolinski Feb 2019

Investigations Of The Potential For Irrigated Agriculture On The Bonaparte Plains: Land Capability Assessment Report, Henry Smolinski

Resource management technical reports

This report describes 55 000 hectares of predominantly red sands and sandy loams — locally referred to as Cockatoo Sands — on the Bonaparte Plains about 70 kilometres north of the Ord River Irrigation Area, Kununurra. It builds on soil surveys conducted in 2009 and 2015, which identified significant areas of red soils in the Kununurra area that could be suitable for agriculture.

The Cockatoo Sands generally have loamy, sand topsoils that grade to sandy loam with depth. The soil profiles are very deep, well drained to rapidly drained, and highly permeable. These soil characteristics support a large range of …
