Productive areas are typically found near any form of structure or change in the channel's character. This includes deep holes, submerged timber, rock groynes, bridge pylons, and the mouths of smaller feeder channels or drains. Areas where the channel bends often scour out deeper holes on the outside of the bend, which hold larger fish. Fishing near the confluence with the Murray River can also be excellent, as it attracts fish moving between the systems.
