Long-term water resource assessments and strategies
Sustainable water strategies and long-term water resource assessments ensure our planning and entitlement frameworks remain adaptive and robust.

Meeting our water challenge
A drier climate, population growth and land use changes are posing threats to Victoria’s water supplies and waterway health. We need long-term assessments and strategies so we can face these challenges. This is why we keep track of our water, manage its use and how it's shared.
TheWater Act 1989 requires that we plan for Victoria’s water security and future supplies through sustainable water strategies and long-term water resource assessments.
Sustainable water strategies
Sustainable water strategies (SWS) help manage water resources and improve waterway health. They identify threats to a region water supply and its quality, so we can plan for the future.
In the past, SWS have reduced water demands, secured water supplies and protected waterways and aquifers.
Long-term water resource assessments (LTWRAs) explore changes in water availability. These changes can impact Traditional Owner values, farming, industry, cities, towns and the environment. They also help determine if there have been changes in waterway health.
The Water Act requires a LTWRA every 15 years. The assessment determines if:
water availability has declined
waterway health has deteriorated due to changes in flow.
The LTWRA for southern Victoria is now complete. The assessment's findings inform our future water planning through sustainable water strategies.
using more desalination and recycled water where possible
better capturing and using the rain that falls on our cities and towns.
This will help free-up river water to get better environmental outcomes and return water to Traditional Owners.
The strategy identifies options to recover up to 99.5 GL per year over the next decade. It signals that we will need extra water recovery over the longer-term to maintain and improve waterway health under a drying climate.
The strategy also includes actions to carry out complementary measures, such as:
This will increase the water available to the environment and will enhance the effectiveness of available environmental water. This will maximise the benefits to waterway health.
