The Living Murray Program (TLM) aims to protect and enhance six icon sites through targeted environmental watering. This watering can do great things for the biodiversity along the River Murray. When we talk about biodiversity, we are talking about the range or variety of living things, including plants and animals.

The icon sites themselves are significant areas of high biodiversity. For example, in the Barmah-Millewa forest, there are 381 plant species (of which 17 are threatened) and 221 animal species (of which 57 are threatened) that are native to the region. Continue reading
Welcome to this week’s River Murray Ops Update.
Yesterday, we issued a flow advice about weir pool level changes at Lock 9.
From 18 November, the Lock 9 weir pool will be temporarily lowered below the full supply level for about one week. It will be lowered by 0.1m/day to around 0.3m to 0.4m below full supply level.
The lowering of the pool is to test how far the water levels can be lowered in summer to minimise impacts on local water users, and pumps supplying water to Lake Cullulleraine.
Please see the flow advice for more information.

The River Murray, a ‘working river’, is regulated with dams, weirs and barrages to help ensure a reliable source of water for communities along the river. These structures, however, have disrupted natural flooding patterns which the floodplains and wetlands along the river rely on. To help restore the balance, The Living Murray program is funding the construction of major water management structures that will help deliver water at several icon sites along the River.
One of these major construction projects is happening at Hattah Lakes, near Mildura. Hattah Lakes is one of The Living Murray’s six icon sites and contains 12 Ramsar-listed wetlands.
Construction of the Cantala regulator. The regulators are designed to not impede natural water movement along the creek lines, but can be closed for managed watering events. This regulator is 100 metres wide and will stand 5 metres tall. The sheet piles are not yet completed and the concrete works have just commenced.

Helping to restore environmental values
The aim for the Hattah Lakes icon site is to preserve and, where possible, restore healthy examples of the original wetland and floodplain communities. The engineering works will provide regulators and levee banks, which will be used to deliver and hold water at the site. Read more about the major construction at Hattah Lakes…
