Nestled between Alexandra, Queenstown and Wanaka, Lake Dunstan is New Zealand’s most recent man-made lake. Long and narrow, it splits into three arms at Cromwell. The Dunstan Arm runs the length of the Cromwell Gorge, the Clutha Arm crosses the Lowburn Flats and the Kawarau Arm extends up into the Kawarau Gorge.

SH6 follows its west side down to Cromwell, while SH8 follows its east shoreline all the way down, continuing on to Alexandra and Dunedin.

While brown and rainbow trout are present throughout the lake, the most productive area to fish is the Clutha Arm, especially where the Clutha River flows in. Salmon arrive in late October to November from the rivers upstream but are otherwise not particularly numerous.

The fish feed on the plentiful population of damsel flies, caddis nymphs, water boatmen, beetles and chironomids (midges).

The best method for fishing the lake is by trolling or harling. Trolling is best at a depth of 3-6m, especially when the water is rough. Harling is successful around the weed beds.

Spinning from the shoreline is also a productive method. Spinning can be very productive especially around any stream mouth and the Clutha River inflow is a popular
spot during the cooler months. As weed can be a problem in many areas, lures are best kept just below the surface to avoid snags.

Fly fishing is also popular and effective. Using polaroid glasses to cut the surface glare and a light rod with a floating line, trout can be targeted as they cruise close to the shore along the weed beds. Dry flies can be successful in the evening with nymphs the better choice for the day. Very clear still weather however can make fishing very frustrating as the trout will not move as close to shore and those that do are easily spooked.

For bait fishing, replace the sinker with a float and drift the bait along the edges of the weed beds.

Rainbow and brown trout in good numbers averaging around 1.5kg. A landlocked population of small salmon and some perch are also present.
