A rock ramp fishway was constructed in 2009 to enhance migration of native fish within the lower Burdekin River. This helps small fish such as mullet to migrate upstream while still allowing the water in the river to be used by locals.
The Rita Island sand dam was identified as a significant barrier to fish movement during certain times of the year.
Barriers to fish movement represent a key threat to fish populations in our region.
Many of Australia's native freshwater fishes need to move in order to breed and survive. Structures such as dams, weirs, causeways and road culverts can act like road blocks, preventing fishes from moving upstream. Even a small drop of 20cm over a causeway can stop fishes moving upstream.
