Winter lakes: bait on the bottom in the deeper bays through the middle of the day, or polaroiding the shallows on the bright days in Tasmania.
Updated Fri, 25 Sept 2026 from live weather and tide data
The plateau lagoon reserved for the fly: wild browns in shallow, weedy water near Miena, with a Bureau gauge at the canal outlet.
Sources: Bureau of Meteorology gauge 508.1, Open-Meteo, solunar calculated for these coordinates.
Penstock Lagoon has cold water and fish that move for very little; fish the sunniest hours. The gauge reads 919.73 m, holding steady. Today brings cloud cover, wind NW around 8 km/h, rising pressure near 1024 hPa and a high of 15 °C. Water sits around 8 °C for the season (estimated). With the full moon, the solunar majors run 10:25 AM-12:25 PM and 10:25 PM-12:25 AM: the windows to build the day around.

The lake fishery: bait or slow lures in the deeper bays; the rivers are closed in NSW and Victoria.
Tie on: Bait on the bottom, running sinker · Heavy blade, deep · Slow-rolled swimbait · Live bait, deepest hole. Prime windows: 10:25 AM-12:25 PM, 10:25 PM-12:25 AM, 4:55 AM-5:55 AM. Cooler at 5 °C with likely rain: fish ahead of the front. The solunar majors shift about 50 minutes later.
Tasmania requires a fishing licence for most fishing, from A$29.00. Tasmania fishing licence: cost, rules and where to buy →

Penstock Lagoon is a lake in Tasmania, Australia, covered from the Tasmania reports and listed in all Australia waters.
Penstock Lagoon is a small Hydro Tasmania storage on the Central Plateau south of Great Lake near Miena, a shallow, weedy lagoon fed by canal from the big lake that the Inland Fisheries Service reserves for artificial fly fishing only, with shore access and a ramp for unpowered and electric craft and a level that the canal keeps steady. It is one of the plateau’s best dry-fly waters, and the Bureau of Meteorology’s gauge at the canal outlet supplies the level and the 30-day chart on this page.
Brown trout are wild and are the fishery, rising to duns and beetles through spring and summer, cruising the weed edges in autumn and tailing in the marshes when the lagoon is up, on the fly because the rule allows nothing else; the lagoon follows the brown trout season the Inland Fisheries Service publishes, first Saturday of August to the Sunday nearest 30 April, computed on the species card, and the code sets the fly-only rule, the no-trolling rule, the 400 mm size limit and the bag of two.
The shore around the lagoon and the ramp are the access, and the fishing is from the bank, wading the edges, or from a drifting boat under electric or oar power across the weed beds; the canal inlet from Great Lake is a current the fish hold in. Polaroiding the flats on a bright day and waiting on the wind lanes for the rises are the methods.
The plateau is cold and the water temperature estimate, labelled as one, is cold for most of the season; the chart barely moves because the canal keeps the lagoon steady. The wind row matters for the wind lanes, the drift and the casting; a dull, still morning is the dun morning; pressure and sky fill the score.
The Tasmanian inland angling licence applies from age 14, one rod or two; our Tasmania licence page has the fees. Artificial fly only, and no trolling from a boat, by the code’s rules for the lagoon; the shore and the ramp are open under Hydro Tasmania’s rules; the Inland Fishing Code is in the sources.
Artificial fly only, from the bank or from a boat that is not trolling, under the Inland Fisheries Service’s rules for the lagoon in the Inland Fishing Code linked in the sources.
Through the Tasmanian brown trout season, first Saturday of August to the Sunday nearest 30 April, computed on the species card.
