A hundred and fifteen kilometres of treeless Monaro tableland stream east of Cooma — rain-fed and flashy, a chain of pools by February and a river in a week, warm enough in summer to make it an autumn and spring fishery, with the Chakola gauge's flow and temperature drawn on the page.
The Numeralla is the Monaro at its most Monaro: a clear, slow tableland stream winding between tussocks across a treeless plain east of Cooma, with undercut banks, long glassy pools, a wind that never quite stops, and brown trout that have watched every shadow that ever fell on the water. It is sight-fishing country, and the fish give you one good chance.
It is also a river with a season, and its own gauge says so. The station at Chakola has read flow and water temperature since 2010. The flow record says this is rain-fed water with no snow in it: a chain of pools between trickles on the dry days, a coloured torrent on the wet ones, spiking after weather and falling away just as fast. The temperature record says that from December to February the water sits above twenty-one degrees, which is stressful for a trout and unkind to one you release.
Between those two facts is the trip. Autumn is the pick, April and May, when the flows are low and readable and the fish are deliberate. Spring is the second-best time, September to November, when the pools are full and the water is climbing back through the teens. Leave it alone in midsummer and come back in autumn. Winter runs cold and reliable, but the trout season is closed on classified waters through it, so check the synopsis.
The fish are browns, with brown and rainbow trout both recorded as stocked in recent seasons. The survey record is thin, seven fish and none of them trout, which is an absence of sampling rather than of fish. Let what you find tell you.
Walk slowly, look before you cast, and give the first cast to the soft edge under the far bank rather than the middle of the pool. Read the dot on the flow chart before you drive, and if the water is coloured or rising while you are on it, get out. This river rises faster than you can see coming.
