What you can plan around is the river’s own record. The flow chart shows how often the Bogan runs high or low, and the temperature chart shows how warm it gets through the year. In our experience, on a river like this golden perch sit on timber, in the deeper holes on the outside of bends and under undercut banks, and they move up onto shallower flats to feed as the water warms.

The survey chart shows how thoroughly the river’s fish have been sampled, which is worth a glance before you read too much into any one species.

Golden perch are the fly fish. Freshwater catfish and spangled perch have been recorded too, and European carp and goldfish are present. Eastern gambusia have been recorded as well.

The small fish are the forage: Australian smelt, bony bream, western carp gudgeons, unspecked hardyheads and Agassiz’s glassfish, with Murray River rainbowfish also reported. That points your fly box at small, pale baitfish patterns in the size 6 to 10 range, and a dark Woolly Bugger for murky water or a slow day.

In our experience golden perch come on as the water warms, from late spring through summer and into early autumn. That is when you fish the shallower edges in the evening and the deeper timber in the heat of the day. Carp on the flats are also a warm-weather game. As the water cools, slow down, fish deeper and expect fewer takes. Check the temperature chart and the flow chart before you pick a date; a steady, clearing river after a rise is usually a better bet than a flood.

A six to eight weight with a floating line covers most of it, with a sinking-tip line handy for the deeper holes. Use a short, strong leader, shorter than your rod, because golden perch live in timber and a fish that reaches a snag is usually gone.

Work each snag slowly. Cast past it, let the fly sink, and bring it back in short strips with long pauses so it hangs in front of the wood. Golden perch often take on the drop or during the pause. If the water is clear enough to see carp tailing in the shallows, switch to a small weighted nymph and a longer, finer leader, and keep your shadow off the water.

The access card lists the ways in, one of them a boat ramp. Treat each as a place to reach the water, not as permission to cross private land; where a spot is on farmland, ask the owner first.

As on any inland river, banks can be steep and muddy after a rise, and the level can change after rain upstream. Check the live conditions before you drive out, carry water, and tell someone where you are going.

No water-specific rule was found for the Bogan. Before you fish, check the current NSW Department of Primary Industries and Regional Development recreational fishing guide for the season, bag and size limits for each species.
