The lower Castlereagh at Gungalman near Walgett: yellowbelly and cod in the plains river, with a Bureau gauge.
Sources: Bureau of Meteorology gauge 420020, Open-Meteo, solunar calculated for these coordinates.
Castlereagh River at Gungalman rewards patience today, with cool water and short feeding windows. The gauge reads 0.16 m, holding steady.

The giant of the inland rivers and the big lakes (Hume, Mulwala, Eildon). A snag fish that eats big lures, and a species with a closed season across the Murray-Darling. Slow it down: heavier spinnerbaits, slow-rolled swimbaits and bait on the bottom next to the deep snags.

Yellowbelly. The bread-and-butter native of the Murray-Darling lakes and rivers; loves warm water, structure and a lure worked slowly past its nose. Slower. Work the deeper timber and the drop-offs with vibes and bait.

Castlereagh River at Gungalman is a river in New South Wales, Australia, covered from the New South Wales reports and listed in all Australia waters.
Gungalman is a gauging site on the lower Castlereagh River north of Coonamble, in the grazing country toward Walgett, where the river’s sandy bed winds under coolibah and red gum on its way to the Macquarie and the Barwon. The Bureau of Meteorology’s gauge at Gungalman supplies the river level and the 30-day chart on this page. The Castlereagh at Coonamble has its own page.
Golden perch are the main catch of the lower Castlereagh when it runs, with Murray cod in the deeper holes; freshwater catfish are protected west of the Divide, and carp are common. The New South Wales Murray cod closure, 1 September to 30 November, applies; the species card computes it.
Access to the river around Gungalman is from the public road crossings and stock routes; much of the frontage is station land. The deeper holes hold fish when the river stops running.
Walgett and Coonamble are the nearest towns with supplies. Carry water and fuel, bring bait for yellowbelly, and check the roads after rain.
The lower Castlereagh has a sandy bed and no large dam, so it runs only after good rain in the Warrumbungles and the central west, and in long dry spells the reach at Gungalman can stop flowing and shrink to waterholes. When a flow comes down it rises, spreads and eventually joins the Macquarie on the way to the Barwon. Golden perch feed on the fresh water in the warm months, the best time to fish, and cod hold in the deeper holes. The chart shows whether the river is running; a flow arriving after a long dry is the moment to go. The country around it is remote grazing land, and the roads close after rain.
The chart shows whether the lower Castlereagh is flowing; it often is not, and a flow after rain is the time to fish. The water temperature estimate, labelled as one, is hot in summer; pressure and sky build the score at Gungalman.
At Gungalman the NSW Recreational Fishing Fee applies, from A$7 for three days; see our New South Wales licence page. The DPIRD rules are in the sources.
