Four hundred and thirty-eight kilometres from the roof of Australia to the sea at Marlo; alpine melt water above the Snowy scheme pondages, a regulated Monaro river below Jindabyne past Dalgety, a gorge across the Victorian border, and a floodplain estuary at the end.
The Snowy begins in a snowdrift under the summit of Mount Kosciuszko and ends four hundred and thirty-eight kilometres later in an estuary at Marlo. The first thing to decide is which Snowy you mean, because at least four rivers wear the name and nobody fishes all of them in a season.
The dams and the border draw the lines. The Snowy scheme pondages and Lake Jindabyne cut off the alpine headwaters. Below the Jindabyne wall the river crosses the Monaro tableland. Below Burnt Hut Crossing it drops into a gorge that crosses into Victoria at Willis. And below the gorge it comes out onto the Orbost flats and turns into a lowland river and an estuary.
The alpine river is the small-stream trip. Between Guthega and Island Bend it is wild, cold pocket water falling through gorge and gravel, holding brown and rainbow trout. The melt peaks in October; in summer, until the April frosts, it fishes best, in our experience, with a four weight and a dry-dropper, one cast per pocket.
The Monaro river below Jindabyne is the cover-ground trip. Its flow is largely what the dam lets down, a broader and more variable water past Dalgety with tussock and open woodland on the banks, and browns that reward a nymph worked through the heads and tails of pools. Two gauges here read water temperature as well as flow, which matters in summer. In our experience spring and autumn are the pick.
The gorge and the estuary are other trips again. The estuary at Marlo fishes for perch and bream.
Eleven gauges sit on the river from Guthega to the Marlo jetty, and the river’s year is drawn from the one above Island Bend with the typical range shaded. Read the nearest gauge before you wade, and check the rules for whichever state’s bank you are standing on.
