Fishways: managing our waterways (Years 7-8)

Dights Falls
Dights Falls, at the junction of the Yarra River and Merri Creek.

Discover the history of Dights Falls, including the importance to the Wurundjeri people – the traditional owners of the area – and the impact of the artificial weir on native fish.

Dights Falls is an artificial weir built on a natural rock bar across the Yarra. It is located on the border of Abbotsford and Clifton Hill, downstream of the junction of the Yarra River with Merri Creek. This is the place where saltwater meets the freshwater flowing downstream in the Yarra River.

Originally, Dights Falls was one of the narrowest parts of the lower Yarra River. This made the Dights Falls site ideal as a camping ground for the Yallock-Bullock clan (Wurundjeri tribe) of the Woiwurrung Aboriginal people. Clans would meet here and trade together.

Before the weir was built, native fish were able to make their way around the natural rock structures and move upstream to breed. Many of these native fish rely on this migration as part of their breeding cycle. This was made difficult with the weir’s construction, but a fishway now allows the fish to move upstream past the artificial barrier.
