Keeping a river flowing in dry conditions can be a significant challenge, which is why Wadawurrung Traditional Owners Aboriginal Corporation (WTOAC) and Corangamite Catchment Management Authority (CMA), supported by both Barwon Water and Central Highlands Water, are working together to maintain flow on the lower reaches of the Moorabool River.
The Moorabool River, which has reservoirs that are key sources of drinking water for the Geelong region, is one of the most flow-stressed rivers in Victoria.
The construction of reservoirs, extraction for drinking water and irrigation, and a number of dams along the catchment are all contributing factors.
Dry conditions in the Moorabool catchment have further added to the issue with below average rainfall since April 2024.
The lowest reach of the river surrounding Batesford is vulnerable to cease-to-flow events, leading to poor water quality and damage to the ecosystem.
Corangamite CMA estuaries and environmental waters project manager Jake Van Dam said that our waterways aren’t able to function as they once did.
“One of the ways we support the health of our rivers and wetlands is through water for the environment,” he said. “Water set aside in storages that is released into rivers and wetlands to support them and the plants and animals that live in them.”
WTOAC is also aiding in this effort with ‘Wadawurrung water’ to support cultural values along the river.
Corangamite CMA chief executive Dr Amber Clarke said that delivering and maintaining flow in such a dry year is a great example of what Traditional Owners, water corporations and CMA were doing to protect rivers.”
