Lake Burley Griffin is the most reliable water in this guide and the least romantic: a six-hundred-and-forty-six-hectare lake in the middle of Canberra, with rowers on it by six in the morning and the parliament looking down on it. What it offers a fly angler is three honest native targets within walking distance of a coffee, on a lake that has never dropped through a drought on record.
It is a native fishery now. The trout that once went in by the hundred thousand stopped in 2003, and the lake has been stocked with golden perch and Murray cod every few years for sixty years. The shoreline is hard and engineered over much of its length, which means bank access is easy and the little structure that exists matters a great deal: rock walls, bridge pylons, drop-offs, weed edges and the mouths of the inflowing creeks.
Golden perch are the first-trip fish. Nearly eight hundred thousand have been released since 1973, they are more widely spread than the cod and more willing to move to a fly, and from November to April they work the drop-offs and the creek mouths. A smaller fly than for cod, fished deep with real pauses.
Murray cod are the second trip. Stocked here in most years since 1980 and confirmed surviving in the 2010s and 2020s surveys, they hold against the rock walls and bridge pylons and eat big flies at first and last light. Check the current ACT cod season before you tie one on.
Carp are the third, and the only fish here you stalk by sight. Through summer they cruise the flats where you can see them, and you lead a single fish with a small nymph and watch for the tilt.
There is no flow or temperature gauge on the lake; the satellite record of its surface is the nearest thing, and it says the lake you plan around will be there. Fish the edges of the day, leave the busy middle of it to the rowers and the coffee, and read the current ACT rules before you go, because they are not the NSW rules across the border.
Water and habitat
Six hundred and forty-six hectares of managed urban water, and the most useful thing about it for an angler is how boringly reliable it is. Satellite observations of its wet surface run monthly from September 1987, more than three hundred of them across thirty-nine years, and the record is drawn on this page. In all that time the lake has never dropped below seventy-seven per cent of its full surface area, and it has been under eighty per cent just twice. The long-run average is ninety. Read that against any farm dam or unregulated lake in the same country and the difference is the whole point: droughts that emptied storages across the tablelands barely register here.
It is a managed water with a hard, engineered shoreline over much of its length, which means bank access is easy, the fish have limited natural structure, and what structure exists matters far more than it would on a natural lake: bridge pylons, rock walls, drop-offs, weed edges, and the mouths of the inflowing creeks.
Fish and forage
The stocking record here is unusually long and unusually revealing, and the timeline is drawn on this page: seventy-six releases across forty-eight years, from 1966 to 2025, totalling just over two million fish. Golden perch lead, nearly eight hundred thousand across twenty-two release years from 1973 to 2024. Rainbow trout follow at half a million, but every one of those went in between 1966 and 2003. Murray cod started in 1980 and were last stocked in 2025, nearly four hundred thousand in all. Brown trout, silver perch, brook trout and freshwater catfish went in too, and every one of those programs ended decades ago; brook trout in 1978, silver perch in 1983, brown trout in 1997, rainbow trout in 2003.
The shape of that record is the story. This lake was once managed as a trout fishery and is now a native one, and it is still running: recent years have been steady, with tens of thousands of fish released in each of the last two. Two caveats worth holding. These are release records, which say what went in rather than what is swimming there now; and stocking has not been continuous, with gaps in the early 2000s and again around 2010.
The survey record bound to the lake confirms what the stocking is producing. Murray cod are recorded in both the 2010s and the 2020s, the useful signal that the fish survive and are found. Golden perch appear in the 2010s. The rest is what you would expect of an urban lake: European carp across three decades, goldfish, gambusia and western carp gudgeon.
What the fish eat is what a weedy, engineered lake grows: damsels and midges on the margins in the warm evenings, small fish along the walls, and for the carp whatever the flats turn up.
When to fish it
The warm months, and the edges of the day. From November to April the golden perch move along the drop-offs and the creek mouths and are the willing fish; the cod come to the hard edges at first and last light; and the carp are on the flats through the middle of summer. Warm overcast days are worth more than bright ones. First and last light matter more here than almost anywhere, partly because the fish prefer it and partly because the lake is busy with boats, rowers and swimmers through the middle of the day.
No flow or temperature gauge is bound to this lake, so there is no conditions record of the kind the rivers carry. The persistence record on this page tells you the lake will be there; the day tells you the rest. Murray cod carry a closed season in the ACT as elsewhere; check it before you fish for them.
How to fish it
An urban lake fishes on structure and light, and this one gives you plenty of both.
For cod, work the hard edges: rock walls, bridge pylons, submerged timber, moored structure and any sharp drop-off close to deep water. Put the fly tight against it, let it sink, and retrieve with long pauses; the take usually comes when the fly is doing nothing. A nine weight and a leader you can pull a fish away from concrete with is the right side of sensible. Strip-strike, keep the rod low, and turn the fish out and away from whatever it is sitting against. The Murray cod page has the full rundown.
Golden perch are the better first-trip target. They are more widely spread than the cod and more willing to move to a fly. Use a smaller fly than you would for cod, a Woolly Bugger in olive or black is the natural start, get it down with an intermediate or a sink tip, and mix short and long pauses into the retrieve. When a fish tracks the fly and will not eat, stopping it dead is the thing that most often triggers the take.
Carp are the sight-fishing here, and worth taking seriously. Through summer they work the shallow flats and margins where you can see them. Lead the fish, let a small nymph, a Hare's Ear or something like it, settle in front of it, and watch for the tilt rather than waiting to feel anything.
Access and safety
A city lake with public foreshore over much of its length, which makes it one of the more accessible waters in this guide. Access rules on a managed urban water are set locally, though, and can be specific about where you may fish, where you may launch, and where boats, rowers and swimmers have priority. Confirm the current rules for the section you want before you go.
The hazards are a city's: hard edges, deep water close to the wall, bicycles on the path behind you, and the one thing an engineered shoreline does not give you, an easy way out if you go in.
Regulations
Check the current ACT rules before you fish. The ACT sets its own recreational fishing rules, including licensing, seasons, size and bag limits, and Murray cod in particular carry specific size and seasonal protections across the Murray-Darling jurisdictions that are not the same in every state. This guide holds no captured ACT rule for this water, so nothing is stated here. Read the current ACT guidance before you fish, and do not assume a NSW limit applies on the Canberra side of the border.
