Morong Creek to the Coxs

Imagery © Esri

Somewhere past the halfway mark on the Gingra Trail, with the pack starting to bite, you hear the river before you see it and understand why nobody fishes the Kowmung. Then you come out at Cedar Ford onto a gravel run between forested walls, water clear enough to count the stones, and understand why you should.

This is the gorge, and it is most of the river: seventy-four kilometres from the Morong Creek junction down to the Coxs, as wild as water gets within a day of Sydney. Bedrock at the top where the headwater gorge finishes, then gravel runs and pools between confined banks for most of its length, the drop easing as it goes until the last few kilometres run almost level. The canopy closes over it, nearly ninety per cent at the bottom, and there is not one cleared paddock on the river.

Know what you are walking in for. One fish is on record here, a blackfish from 1910. Nothing has been stocked and nobody runs a survey. That is an absence of sampling, not of fish: a gorge this steep, cold, shaded and remote is where wild brown trout persist once the roadside water has been fished down. Treat it as unproven, and let a day on the water do the counting.

The trip is a two-day walk with a four weight. In on the Gingra Trail from the Kanangra tops, about fourteen kilometres to Cedar Ford, base there, fish up into the tighter water one day and down through the longer runs the next. From late spring until the first frosts is the time, with a dry-dropper fished once into every pocket and an Elk Hair Caddis in the evening runs. The trout classification that closes the headwaters in winter does not apply here, but the ordinary NSW rules do, and the bottom of the gorge runs toward WaterNSW's drinking-water special area, where the water authority's rules replace the park's.

The river's only gauge sits at Cedar Ford, right where the trail meets the water, and its readings sit under Conditions. Read it the day before you walk, not the morning of. After rain on the plateau this river colours before it rises, and a wet forecast is a reason to wait.

When things happen

The year on this water

A guide's calendar, not a rulebook

  • Dry-dropper season · Oct to Apr A buoyant dry and a tungsten nymph, fished once into every pocket. The one rig for a river you carry in on your back.
  • Terrestrials off the overhang · Nov to Mar Beetles, ants and cicadas out of the closed canopy. A fish tight under the timber in the afternoon is waiting for one.
  • Caddis at dusk · Nov to Apr The gravel runs below Cedar Ford come alive in the last light. An Elk Hair Caddis until you cannot see it.

Water and habitat

Gorge country from end to end, but not the same gorge all the way. The fall of the river on this page shows the confined bedrock of the headwaters finishing a few kilometres below Morong Creek, and from there the bed is gravel between walls that never quite let go. The occasional small flat where a side creek comes in, then walls again. The gradient eases steadily downstream and the runs lengthen: by Cedar Ford the pools are long enough to fish properly, and below it the river is a chain of gravel runs, riffles and pools that a Monaro angler would recognise, only with a cliff on each side.

The bank survey from space is the other half of the picture. Closed canopy for most of the length, open enough here and there to let light down, and no cleared or farmed ground anywhere. The bottom five kilometres before the Coxs are the darkest water on the river. That shade is what keeps this stretch fishable on afternoons that would shut down an open tableland stream, and it is what makes the terrestrials matter more than the hatches.

Cedar Ford is where the river is measured and where the Gingra Trail comes down. It is the natural base for a two-day trip: fish up into the tighter water on one day and down through the longer runs on the other.

Fish and forage

Wild, and almost entirely unrecorded. The only survey record bound to this water is a single river blackfish from 1910. Nothing has been stocked, and nobody runs a survey here. That is an absence of sampling, not of fish. A gorge this steep, cold, shaded and remote is exactly where brown trout persist in the Blue Mountains once the roadside water has been fished down, and the headwaters above this stretch are classified as trout water by the department. Treat it as unproven and let a day on the water do the counting. If you find trout here and it fishes well, you know something almost nobody has written down.

What they eat falls from the trees. Beetles, ants and cicadas out of the closed canopy from late spring through summer, onto water that sees a fly perhaps once a season. In the gravel runs, caddis larvae under every stone and a good hatch in the evening from the runs below Cedar Ford.

When to fish it

Read the Conditions card on this page before you decide, and read it the day before you walk, not the morning of. Cedar Ford reads flow, height, temperature and turbidity, and the turbidity is the one anglers forget: after rain on the plateau the river colours before it rises, and a turbid reading means the pockets are unreadable for a day or two even if the flow looks manageable. This is a rain-fed gorge, not snowmelt country. After a solid fall above Kanangra the river comes up fast and is genuinely dangerous through the confined sections. Give it a few dry days.

From late spring until the first frosts it is at its best: settled, clear, cool under the canopy, with the terrestrials falling and the evening caddis on. Autumn is the quiet prime. A closed gorge like this runs cooler than the same day on the open Monaro, which is a reason to fish early and keep fish wet on a hot day, not a reason to assume the water is cold.

If the forecast is wet, wait. If the river is up or dirty when you get to the bottom of the trail, that is your answer for the trip, and you fish the edges from the bank or you rest.

How to fish it

You are covering ground on foot in clear, confined water, and the first cast into a pocket is usually the only one that counts. Fish the seams along the bedrock, the soft edges behind boulders, and the tails of the gravel runs once the gorge opens a little. Keep your approach low and your shadow off the water.

A four or five weight and a floating line covers everything. The dry-dropper is the rig: a Stimulator or a Royal Wulff you can see in broken light, with a tungsten Hare's Ear or Pheasant Tail two feet under it, so the fish choose the level without you changing flies every ten minutes. In the evening runs below Cedar Ford, an Elk Hair Caddis on its own until you cannot see it. When the water is carrying colour, or the fish are deep and tight after a rise, a small Woolly Bugger swung through the deeper slots.

Casting room is the job. Roll casts, bow-and-arrow casts into pockets under the timber, and next to no room behind you almost anywhere. A short leader you can control beats a long one you cannot.

Wading is the real work, and it is slow. Bedrock turns slick, the walls pinch in, and a fall in this country is a long way from help. Felt or studded soles earn their keep on this river. If you cannot see the next footing, do not take it.

Access and safety

Remote gorge, reached almost entirely on foot. The two mapped walks are long: the Gingra Trail from the Kanangra tops drops to the river at Cedar Ford, and the Uni Rover Trail comes in further upstream off the Morong Creek fire trail, each around fourteen kilometres from the car. Roots Ridge, Bulga Ridge and Black Snake Bend are bushwalkers' routes into the gorge, named on the maps anglers pass around but not mapped as tracks, and they are for people who already know them. Scotts Main Range Road and the Denis Ridge trail come within several hundred metres of the river on the eastern side, but the last stretch to the water is off-track and steep. All of it is Kanangra-Boyd and Blue Mountains national park; a track on a map is not a right to walk it today, so check the current NPWS alerts before you go.

The bottom of the gorge runs toward WaterNSW's special area around Sydney's drinking-water storage, where the water authority's rules replace the park's. Check with WaterNSW before you plan on fishing that far down.

Treat this like the remote walk it is. Carry what you would need to look after an injured person overnight a long way from a road, tell someone your plan and your exit day, and give yourself the daylight to climb out comfortably rather than in the dark. There is no signal in the gorge and there is no second gauge on the walk in; the call is yours, standing on the bank.

Regulations

NSW DPIRD's general trout classification on the Kowmung stops at the Morong Creek junction, and this stretch is below it, so the classification does not apply here. What does apply is the ordinary NSW freshwater rulebook for the fish you catch, trout included.

Check the current NSW freshwater synopsis before you fish. The numbers move. Do not take them from this page.

National parks set the rules here

Three things hold on every NSW national park water on this guide, not just this one: a track can close at short notice for weather, fire or maintenance with no warning on this page; some areas carry special-area rules that aren't always published anywhere online; and a locked gate is the answer for the day, not an obstacle to find a way around. Check current alerts and closures with NPWS before you go — everything below describes the country, not a guarantee of what you'll find when you get there.

Questions anglers ask

Is there a live gauge on this stretch?

Yes. The Kowmung River at Cedar Ford station sits where the Gingra Trail meets the river and reads flow, height, water temperature, turbidity and conductivity. Its latest readings are on this page under Conditions. It is the only gauge on the river, seventy kilometres below the source, so it tells you what the catchment is doing rather than what one pocket is doing.

Does the trout classification apply here?

No. NSW DPIRD classifies the Kowmung as general trout water above, and including, Morong Creek. This stretch is below that junction, so the ordinary NSW freshwater rules apply. Check the current synopsis for what those are.

How long is the walk?

Around fourteen kilometres each way on the two mapped walking routes, the Gingra Trail off the Kanangra tops down to Cedar Ford and the Uni Rover Trail in from the Morong Creek fire trail. Both are full days with a pack. The bushwalkers' routes, Roots Ridge, Bulga Ridge and Black Snake Bend, are named but not mapped as tracks.

Can I fish the lower Kowmung near the Coxs?

The bottom of the gorge runs toward WaterNSW's special area around Sydney's drinking-water storage, where the water authority's rules replace the park's. Check with WaterNSW before you plan a trip that far down.
