The Snowies give rainbow trout two tempos. The lakes, Eucumbene, Jindabyne, Tantangara and the smaller pondages, are where most visiting anglers actually catch them: wind lanes, drop-offs, creek mouths and a fish that will come up through the column when the evening rise starts. The Eucumbene River and the high streams inside Kosciuszko are the other half, compact, cold and readable, with rainbows mixed among browns in the same pockets and a run of lake rainbows up the river in the spring water as the season opens.

This is not the Monaro. The tableland east of Cooma is open frost-plain and undercut brown trout water. The Snowies are the range and the Snowy scheme lakes on its western edge. NSW’s local fishing guide folds both into one Monaro district; anglers do not. Fish the lakes when you want a rainbow session. Fish the rivers when you want to read individual lies. The national rainbow trout page has identification, general tactics and the brown trout lookalike; what follows is only what changes up here.

On the Eucumbene the rainbows will hunt down a big dry imitating the Kosciuszko dun from metres away and chase it downstream before smashing it. The stretch from Providence Portal to Denison, best known for its autumn browns, is worth fishing early in the season for smaller bullet-like lake-run rainbows, fewer than they were but not gone, and between Four Mile Creek and Kiandra Bridge in October a big rainbow turns up while you are nymphing for the twelve-inch fish. Below Tantangara Dam the Murrumbidgee holds rainbows in stunning density and condition, numerous and fast-growing like a spring creek. Up the Geehi above the Valentine Creek junction they average half a pound, and the small Kosciuszko streams, with short casts and simple drifts to willing fish, are the place to introduce a beginner.

On the big open lakes, blob-style flies have at times been a game changer for wild trout feeding at depth, rainbows included. Landing a big one from a lake bank on a long light rod is where tips break: keep the butt in line with the tip rather than high-sticking a fish up the bank.

Start on a lake shore if you have not fished the Snowies before. Walk a windward bank in the last two hours of light, fish a Woolly Bugger on a floating or intermediate line along the drop-off with slow pulls and long pauses, and be ready to switch to a parachute Adams when fish start showing in the last of the light. NSW DPIRD’s Snowy Mountains guide rates a size eight to twelve Bugger as a strong low-light choice for rainbows on those lakes, and a size fourteen to sixteen Adams during the warm-weather evening hatches.

Choose the Eucumbene when you want to learn by reading water. Fish upstream, keep your shadow off the lie, and put the first cast on the soft edge rather than the middle of the current. Early in the season, with the lake rainbows in the river, a heavier Pheasant Tail or Hare’s Ear swung through the runs is the fly; by Christmas a size fourteen to sixteen Adams and a small weighted nymph on a dry-dropper are the starting pair on the alpine creeks.

A five or six weight earns its place on a windy lake; a four or five is enough on the rivers. Carry a floating line, an intermediate for the drop-offs, and enough 3X to 5X tippet to change without rebuilding.

The useful box is small: a Bugger in olive or black, an Adams, an Elk Hair Caddis for the evening riffles, a slim nymph or two, and a hopper for the warm afternoons along the tussock. Presentation and depth lose more fish here than pattern choice.

Summer is when the lakes earn the drive: evening hatches of midges, damsels and mayflies on still days, and streamer water when the wind is up. Spring on the creeks, once the rivers open on the October long weekend, is nymph and small-dry water for the lake rainbows running up in the melt, often before the lakes have really switched on. From Christmas the creeks are dry-fly water for the resident fish, and autumn can fish either until the high streams shut down and the lakes take the trip again. Check the Snowy Mountains page and the forecast before you choose; alpine weather turns faster than the calendar.

NSW applies freshwater bag and size rules and separately identifies trout waters and seasonal closures, and the Eucumbene above the lake is artificial fly and lure water and a trout spawning stream with a winter close; that river’s pages state the shape of the rule. Check the current NSW freshwater limits and the current freshwater closure notices before you fish. A line on the map is not access permission: use formed public access and the authority-checked angler access points pinned on the water pages, obey gates and signs, and do not assume a bank is public because the water is fishable.
