Location

Key catchment map Moonie River

The Mooni catchment is in far north NSW along the NSW-Queensland border. The Mooni River enters the Barwon River between Mungundi and Collarenebri.

Catchment area

The Mooni River has a total catchment area of 14,370 square kilometres. Less than three per cent of the catchment lies within NSW (420 square kilometres).

Rivers and tributaries

The Mooni River begins near the small village of Mooni in southern Queensland and flows south-west, crossing the NSW border about 50 kilometres upstream of its confluence with the Barwon River. The Mooni River is unregulated with only one weir along its length.

Real-time flow data

The department monitors the conditions of river systems in NSW and provides regular updates on water levels, rainfall, water temperature and electrical conductivity.

Major water users

Land use in the catchment is mainly grazing and dryland cropping. Water is used for irrigation, stock and domestic supply.

Key water management issues

The Mooni River is an unregulated stream and river flows are highly variable. Sharing the catchment's water resources fairly between NSW and Queensland, within extraction limits, set by the Murray-Darling Basin Cap is a key water management issue. An intergovernmental agreement and water sharing plans are being developed to set long-term rules on how water can be accessed, used and traded in both states.

Water sharing plans

To preserve water resources in river and groundwater systems for the long term, it is critical to balance the competing needs of the environment and water users. Water sharing plans establish rules for sharing water between the environmental needs of the river or aquifer, and water users, and also between different types of water use such as town supply, rural domestic supply, stock watering, industry and irrigation.
