A small, artificial fly and lure only trout stream that feeds the Snowy River in New South Wales. Brown and rainbow trout are stocked, and FlyLife's writers describe fish around a pound with the odd cruiser well above that for anglers prepared to work.
The Mowamba is a small trout stream that feeds the Snowy River, and the reason to drive to it is the chance of a better fish than a stream this size looks able to hold. FlyLife’s writers describe a healthy run of trout around a pound, with some cruising fish of two to three pounds, for anglers willing to work for them.
By FlyLife’s account it rises in Kosciuszko National Park and is spring-fed along its course, running down to its junction with the Snowy. You will also see it called the Moonbah. The change that matters to you is in character, because FlyLife’s writers describe heavy weed on the longer, shallower stretches.
That gives you two trips, and the first is where to start.
Start on the deeper, cleaner runs for brown and rainbow trout, both stocked, in the warmer months with a dry fly or a small nymph, walking in from one of the ways in named on the access card. The whole river and every creek above the Snowy junction is listed as artificial fly and lure only water, which in practice means no bait anywhere on it, from the top down to where the Snowy begins. Check the current NSW guide for the season and licence before you go.
The second trip is the weedy shallows, and it is a hunt rather than a drift. FlyLife’s writers say the weed makes nymphing difficult there, so leave the weighted fly in the box, walk slowly, and look for the cruisers before you cast. Save it for a bright, calm day once the runs are familiar.
Pick a way in from the access card, tie on a small dry, and walk upstream with your eyes on the water.

Water and habitat

A small stream that flows into the Snowy River. FlyLife’s writers describe it rising in Kosciuszko National Park and being fed by springs along its length, and the gradient profile shows how quickly it drops from the top to the junction. The bank cover chart shows what grows along it.
The same writers describe heavy weed growth on the longer, shallower stretches. In our experience, weed on a spring-fed stream means food, and it is where the bigger fish often cruise and feed. The deeper runs between are the other half of the river: trout hold at their heads and along the seams beside the faster water, where the current brings the food to them.

Fish and forage

Brown and rainbow trout are both stocked here, and the stocking chart shows the releases season by season. In practice that means you will meet a mix of fish: recent releases that come readily to a fly, and older fish that have learned the water and take more work. FlyLife’s writers describe a healthy population around a pound, with some cruisers of two to three pounds.
No insect survey was found for the Mowamba, so the fly box is a guide’s read. Weedy, spring-fed water usually carries plenty of small nymphs and snails under the surface, and in summer the banks put beetles and grasshoppers on the water. A size 14 to 16 Parachute Adams, a size 16 Pheasant Tail or Hare’s Ear, and a hopper for hot afternoons will cover most days. Add a small Woolly Bugger if you want to try the lure side of the rule on the deeper runs.

When to fish it

No month-by-month account of this river was found, so this is a guide’s read, and the season itself comes from the current NSW guide. Early in the season, while the water is cold, fish a small nymph through the deeper runs. From early summer the dry fly comes into its own, on the runs and on the shallows, and warm afternoons bring the terrestrials. As the weather cools into autumn, go back to the nymph on days when nothing is showing.

Small nymph through the runs early on
Fly · Oct–Nov
A guide’s read, not a record. A size 16 Pheasant Tail or Hare’s Ear drifted through the deeper, cleaner runs while the water is still cold. Keep it off the weedy flats, where FlyLife’s writers say heavy weed makes nymphing hard. Check the current NSW guide for the season before you plan an early trip.
Dry fly through the warmer months
Fly · Dec–Mar
A guide’s read. A size 14 or 16 Parachute Adams is the first fly to tie on once fish are looking up, and it sits clear of the weed on the shallow stretches.
Terrestrials on warm afternoons
Food · Dec–Mar
A guide’s read rather than a survey. Small streams in high summer usually carry beetles and grasshoppers off the banks, and trout on weedy, shallow water are often looking up for them.
Hopper against the bank
Fly · Jan–Mar
A size 12 or 14 hopper on a hot afternoon is a good bet for the better fish, including the cruisers FlyLife’s writers describe.

How to fish it

A three or four weight with a floating line suits a stream this size. On the runs, fish upstream with a dry or a dry and a light dropper, and cover the head and the seam before you move.
On the weedy shallows, change the approach. A weighted nymph will foul, as FlyLife’s writers warn, so fish a dry or a hopper, or an unweighted nymph just under the film. Stand still, find a cruising fish, work out its beat and put one cast a metre ahead of it. On a stream this small the first cast is usually the only one that counts.
Bait is not allowed anywhere on the river or its creeks above the Snowy junction. Flies and lures only.

Access and safety

The access card names the ways in. Treat them as places to reach the water, not as permission to cross private ground; where a fence or a sign says otherwise, respect it.
As on any high-country stream, the weather can turn quickly. Carry a warm layer and a rain shell even on a fine morning, and tell someone where you are walking and when you expect to be back.

Regulations

The whole of the Mowamba River, also called the Moonbah, and its creeks and tributaries upstream from its junction with the Snowy River, are listed as artificial fly and lure only waters under the NSW trout and salmon fishing closure notification of 2023 and in the NSW Department of Primary Industries and Regional Development trout water listings. The Snowy River itself is not included.
No season, bag or size rule specific to the Mowamba was found beyond that listing. Check the current NSW Department of Primary Industries and Regional Development recreational fishing guide before you fish, for the trout season, the licence, and the bag and size limits.
