Otago Weekly Fishing Report - 23 January 2025

Hot days, hot lakes

The past week has brought some classic hot summer days to our large lakes, kicking the food chain into overdrive. Shoals of bullies are gathering in the shallows of Lake Wakatipu and Lake Wānaka, while clouds of water boatmen are filling the shallows of Lake Dunstan.

Trout are eager to take advantage of this annual bounty, but they’re not fond of the warm, oxygen-poor waters. Trout will be feeding in the shallows at first light but by mid-morning they’re retreating to cooler, deeper water.

Tiny brown soft baits are great for fishing the shallows, imitating bullies and juvenile trout. For flies, boatmen or damsel patterns are great, or a big blowfly pattern.

Another great spot to try in the lakes is where a cool stream or river meets the lake. The cool, oxygen-rich water provides a thermal refuge during warm weather.

 

Waiting on Loganburn

Reports suggest that cicada activity at Loganburn Reservoir, also known as the Great Moss Swamp, has yet to reach its peak, especially compared with the cicada action occurring on backcountry rivers. Anglers have noted limited rises and a general lack of action during the middle of the day.

One angler reported seeing only five rises in an afternoon, with four of them to his fly, resulting in two catches. For spin anglers looking to improve their chances, the tried-and-true method of pairing a bubble float with a cicada fly is worth considering. This technique is especially effective for reaching distant fish or dealing with windy conditions later in the day.

Most success has been reported in the late evening, between 8pm and 9pm. Spin fishing with black soft baits and spinners has yielded occasional catches, while bait fishing with worms remains a dependable option.

Often the fishing at Loganburn does not reach its peak until February when the trout can become singularly focused on devouring cicada blown onto the water. Evening sedge rises can also be spectacular but, again, the surface activity seems quiet for this time of year.

For more details, the next article offers essential tips and tricks for cicada fishing.

 

Convincing cicadas

Cicadas have been active in some areas for the past few weeks, and their numbers have increased over the past week. Trout are taking advantage of this annual bounty. You might even see them openly feeding in the middle of the day, gulping down cicadas from the surface.

Here are a few tips for successful cicada fishing:

  • Use the right-sized imitation: Cicadas can vary greatly in size. In the western parts of our region, like the Makarora River, you might need a large #8 hook size imitation for the large ‘bush cicadas’ present. In other areas, like Poolburn Reservoir, the smaller ‘tussock cicadas’ may require a smaller #14 hook. Having a selection of sizes in your box is useful. Find a live cicada in your fishing area and match the fly size to the real bug. Colour is not as important as size, so having the right size in the wrong colour will get more hook-ups than the right colour in the wrong size.
  • Use heavier line: A heavier tippet, such as 8lb test, can help your cast "roll over" more easily, especially in riffled water. This will help keep your tippet straight and allow you to present large flies more effectively, even in windy conditions. Heavy line also makes it easier to reel in the trout, shortening the fight and giving the fish a better chance to swim away safely.
  • Try fishing in the afternoon: As the day warms up, insect activity increases, and the afternoon wind often blows cicadas onto the water. This can create great fishing conditions.

 

Lower Clutha still firing

The Lower Clutha/Mata-Au River below Balclutha continues to deliver excellent fishing, with large numbers of perch and brown trout being caught. Hadlee, from Hunting & Fishing Dunedin, has been making the most of the action by drifting along weed edges and drop-offs in his boat, casting back towards the shore.

Small, naturally coloured soft baits have been effective for both trout and perch. For anglers targeting perch specifically, Hadlee suggests using brightly coloured soft baits in pink or chartreuse for the best results.

Hadlee has found success fishing the incoming tide, as fish moved into the shallows to hunt baitfish. For cruising trout, fishing with a small streamer or a dry-dropper set-up has proven productive. When casting, take care to minimise water disturbance or shadows, as the fish can be easily spooked.

 

Greenstone Controlled Fishery

Bookings for the Greenstone Controlled Fishery beats open at midnight on Monday, January 27. A Controlled Fishery Period applies from February 1 to March 31 each season on the Upper Greenstone River, from the swing bridge at McKellar Hut to the Sly Burn confluence.

The Controlled Fishery period requires anglers to make a booking to fish the Upper Greenstone River. This ensures anglers will have exclusive angling access to a determined stretch of river (a beat) for the period of their booking. Beats are booked via an online booking system that operates on a first-come, first-served basis.

A booking may be made for one primary angler and one companion angler who must both hold a valid Whole Season Fishing Licence and an Otago Designated Waters Licence. Bookings can only be made up to five days in advance of your intended fishing trip, including on the intended day of fishing. You can select up to a maximum of three consecutive days per booking.

Here’s the weekend outlook:

 

Dunedin

Saturday is shaping up to be the best day of the forecast for Dunedin this weekend, with clouds expected to clear, fine conditions, and light easterly winds. Rain on Thursday will hopefully have cooled many of the coastal streams, increasing fish activity. However, rain showers and southerlies are forecast to develop throughout Sunday.

The Taieri River at Outram was flowing at 4.07 cumecs. The water temperature was 19 degrees C.

Rain showers on Thursday and Friday are expected to cool and raise many of the low-flowing rivers around Wānaka, providing some relief after multiple 30-degree days. Anglers will be well-positioned to take advantage of these improved conditions, with Saturday through Monday forecast to bring ideal fishing weather, featuring light winds and clear skies. The only slight blemishes on the forecast are the northerly winds developing on Saturday and overcast clouds lingering during early mornings on Sunday.

Alexandra

Warm, calm conditions on Saturday provide the perfect opportunity for anglers to head up to local reservoirs and target rising fish. While access tracks may still be a bit greasy following Thursday's rain, the warm air temperatures and sun should help dry them quickly. Don’t forget to pack sunblock, as clouds are expected to clear as the day progresses. Showers and southwesterlies are forecast to develop on Sunday, bringing cooler conditions.

Clutha Regional Forecast

Saturday is the highlight of the weekend forecast for the Lower Clutha, with slightly overcast conditions and light winds expected to clear as the day progresses. This makes it an ideal time to take advantage of rivers likely to be refreshed by Thursday's rain showers. However, Sunday’s forecast predicts showers, possibly heavy at times, accompanied by strengthening westerly winds.

The Pomahaka River was flowing at 5.4 cumecs.

The lower Clutha River at Balclutha was flowing at 452 cumecs.
