Gingin surface water allocation plan

The Gingin surface water allocation plan sets out our approach for managing the Gingin surface water resources and provides allocation limits.

Plan release information

The Gingin surface water allocation plan was released in April 2011.

Supporting documents for the plan are also available:

The methods report describes how the department decided on the annual allocation limits for each of the surface water resources.

Water allocation planning for Gingin surface water

Declining trends in rainfall and streamflow across the area indicate that any increase in water abstraction will lead to unacceptable impacts on existing users and the environment. The department capped abstraction from the Gingin surface water resources and has set a target for recouping unused entitlements to prevent future over-use.

Plan area

The Gingin surface water plan area is about 90 kilometres north of Perth and covers 1,430 km2.

Most of the area is in the Shire of Gingin, except for a small portion in the south-east, which is in the Shire of Chittering.

Water resources

The plan applies to Lennard, Moondah, Gingin, Wallering, Mungala and Quin brooks and their tributaries.

For management purposes, the plan area is divided into 12 resources with Gingin Brook divided into seven resources.
