Stream gauging stations play a pivotal role in managing Victoria’s water resources, but there is little public knowledge about them and their role in maintaining healthy and effective waterways. Stream gauging stations help with maintaining an efficient and contemporary gauging network that is vital for effective water resource management. These stream gauging stations also underpin the Bureau of Meteorology’s flood warning system and link with the Victorian State Emergency Service’s emergency response.
One issue that can arise out of these stream gauging stations is that they can act as blockages to safe passage. This includes the upstream and downstream movement of native fish over the controlled area.
To help alleviate these issues, DELWP’s monitoring and data team have been working with the Arthur Rylah Institute (ARI), Glenelg Hopkins Catchment Management Authority (GHCMA), Aboriginal Victorians and Ventia to construct fishways at Sandford (Glenelg River) and Homerton (Darlot Creek) in the state’s south-west. These rocky diversions also known, as a fish ladder or a fish pass, will allow fish passage while maintaining accurate hydrological flow measurements.
We are continuing to engage with the GHCMA and the local Aboriginal groups to install a fish trap at Homerton.

ARI scientists able to tag eels in amazing migration event
Huge ocean swells near Warrnambool briefly opened the Hopkins River mouth to the sea, allowing scientists the unique opportunity to witness an eel migration event and also attach 'pop-up' satellite tags to some of the eels.
