“A few seasons had passed since my last trip to Arthurs Lake, and I was excited to visit the ‘Cowpaddock’ for a pre-Christmas mission …”









My day begins at 4.00am, blissfully dreaming about trout engulfing mayflies, when I am rudely awoken by my Labrador slurping my nostrils in need of the front lawn. The alarm was set for 5.00, but there is no chance of snoozing now, with a racing brain and a dog snoring like a drunken sailor at the foot of the bed. Oh well, time to get up, put on a pot of coffee and piece together my fishing swag.
In recent weeks the weather bureau forecasts had been somewhat schizophrenic, with predicted thunderstorms turning into T-shirt weather and gale-force winds wreaking havoc on calm days. This made guiding challenging, too. A few seasons had passed since my last trip to Arthurs Lake, and I was excited to visit the ‘Cowpaddock’ for a pre-Christmas mission with my mate Sam.
Drifting across Sevenpound Bay on Arthurs Lake.
Arthurs, as it is affectionately called, is one of Tassie’s best known and at one time most-visited lakes. Renowned for its unusual structure and scenery, there are giant electrical towers reaching to the sky, large islands dotted with long-dead silvery trees and shallow grassy bays that are wonderful to walk and wade. It’s a lake that offers fantastic fishing for boat and shore-based anglers alike.
Arthurs is home to an impressive number of wild brown trout. The tiny rills and creeks fringing the shoreline provide perfect spawning conditions to maintain a self-sustaining population. Their diet is rich with mayflies, midges, gum beetles and native galaxiid fish. Recent reports had been somewhat unfavourable, with rumours suggesting cormorants had cleaned out all the fish. However, I remained optimistic!
I’ve always found Arthurs to be equally fascinating and frustrating. It doesn’t always give up fish easily. All those reports of supreme mayfly fishing have eluded me over the years; I continually present, full of optimism, only to have another bad day — but I keep coming back!
Fast forward a few hours, and the boat slides off Sam’s trailer into Jonah Bay. The wind is whipping the water into soft pavlova-like peaks under the towering power lines that stretch across the lake’s northern end. Our hopes of a warm summer day flicking dries to greedy rising trout are quickly shattered. Mother Nature has a funny way of crushing your fishing expectations — especially in Tassie!

As we start out, the north-westerly is pushing 40 km/h and constantly changing its mind on which direction to blow. Patches of sporadic clouds are peppered with bright sun — the conditions are not favourable, but we’re up for the challenge.
I chuck the drogue overboard as the boat rollicks across the turbid water, setting up the first drift across Sevenpound Bay. A flock of forty-odd cormorants in the distance, begging to be turned into feather dusters, eye us off as enemies. Sam wrestles the outboard as we steady ourselves, ready for a day pulling wets on a famous mayfly lake — in summer!
The 9-foot 5-weights are quickly re-homed in their protective tubes as we both rig up 10-foot 6-weights with intermediate sinking lines. I tie on a size 10 Humungous (my go-to wet fly) on the point and a size 12 Shrek on the dropper with six feet between the flies. This dynamic fly duo has been unsurpassed in the past few seasons, dispensing many toothaches to unsuspecting trout. It’s too damn windy for me to attempt three flies, loch-style. On the other hand, Sam begins slinging three wets before I’ve finished attaching the first. Oh, to have good eyesight again!
1.6m of water was the sweet spot!
As we reach the middle of the bay, a quick check on the sounder reveals the water depth to be 1.6 metres. The tinny moves quickly in the wind, even with the drogue firmly taking hold. I throw out a few quick casts to get into the rhythm, with fast strips to test the water. Generally, I like to strip fast in strong winds and reduce the speed as it recedes — a reliable approach that consistently rewards.
Moving closer to shore, the water level drops to 1.2 metres, and we are both delighted with solid takes on fast retrieves, simultaneously welcoming two golden speckled Arthurs brownies to the boat and confirming that fish are present and hungry! Sam manages to snap a photo and captain the boat as the wind pushes us dangerously close to the rocky eastern shore of the bay. With a big smile on his face, he says, ‘Let’s do that again’!
In windy weather, I get a bit lazy and tend to stick to the same line and flies. Changing rigs with wayward tippets and lines zinging around my head drives me crazy. On the other hand, Sam loves to change his lines and flies continually. He has a set of spools pre-prepared to switch out easily. This sets up an interesting experiment: my aversion to fumbling in the wind and Sam’s curiosity for mixing it up.
The next hour or so rolls on with a welcoming, repetitive rhythm. We motor back to the middle of the lake, curse the wind, drown the drogue and wait until the boat drifts back into 1.2 metres of water. This depth was the absolute sweet spot, with the trout aggressively responding to a fast stripped wet fly.
Sam changes over to a type 5 sinking line and a team of bead-headed Woolly Buggers. This is usually when his catch rate goes through the roof, and my numbers remain unchanged. Surprisingly, the trout keep hitting my flies, with very little interest shown in his deeper offering. At this point we decide to move further north into Cowpaddock Bay. Another fly change for Sam, as my thoughts drift off, happily watching a ‘wedgie’ hang in the wind above us. A couple of shore-based anglers are battling with the wind in their faces, having no choice but to cast into it from their position.
A beautifully conditioned Arthurs brownie.
Interestingly, the Cowpaddock trout are initially hungry in 1.4 metres of water, a little deeper than their friends down the way. A few decent taps fool us into thinking this is the trout highway, but the action quickly disappears. With a couple more runs over the same spot without any luck, a seam of well-defined wind lanes forms to our right, enticing us closer to the tree-lined shore.
After another check of the sounder, the boat is back in 1.2 metres of water. Here we go, I’m thinking, as my confidence rises again. I uncharacteristically complete a fly change in the lulling wind, swapping my point fly for an orange bead-headed Magoo along with the Humungous. I’m glad I did, as I am quickly rewarded with a fish to the net as Sam enquires about my fly choice. ‘Nice work,’ he says. His type 5 line is beginning to snag on the submerged rocks, so he switches back to a type 3 line and a Humungous/Magoo combo to mirror my setup.
As the boat pushes further towards the rocky shore the action ramps up again, with both of us receiving equal interest in our fly offerings. I begin slowing the retrieve in the receding wind, with longer pauses between strips and an even slower ‘hang’.
A solid trout smashes the Magoo, just 50cm from the boat’s bow, scaring me half to death in the process. The fish puts up a proper fight, stripping more than its fair share of line from the spool, and I’m delighted to welcome a little extra weight in the net this time. Ah, the good old hang!
Windswept after a good session with plenty of fish boated and more taps than I can count, we retreat to the boat ramp. Sam laughs at how we’ve had the most success with two lairy, bright, wet flies on a Tasmanian mayfly lake in mid-December.

In the past, I have been guilty of cursing the weather; getting cranky when the conditions don’t match my expectations and available fishing time. Nowadays, I love the challenge of fishing in any conditions — rain, hail or shine. It wasn’t mayfly fishing, but boy, was it fun! As Sam says, they’re always there; you just have to figure out what they want. It’s super satisfying to catch fish on days when you may not have ventured out, but changing your approach is critical to success.
