In addition to the general information for all fishway types, the following applies to vertical slot fishways.

Requirements for effective passage

Vertical slot fishways maintain constant velocity and turbulence levels throughout the fishway at varying river flows and are able to operate over a relatively wide range of headwater and tailwater levels[1].

Suitability and limitations

Vertical slot fishways typically allow a broad range of fish species to pass when appropriately designed, but can be expensive to construct.

There are several vertical slot fishways across coastal and inland rivers of Queensland, mostly south of Mackay and including the Murray-Darling Basin.
