Lake Wānaka fills a glacial valley 42 km long at the foot of the Southern Alps, about 10 km wide at its southern end and up to 311 m deep. The Makarora comes in at the head and the Matukituki in the west, and the Clutha Mata-Au leaves from the south-east corner near Albert Town. Brown trout, rainbow trout and landlocked quinnat salmon all breed here on their own. Chinook were released in 1918, and all three species may also have come up from fish already in the Clutha. What sets Wānaka apart for a fly angler is the shallow, weedy West Wānaka bays, where you can sight fish to browns cruising the edge.
In Glendhu, Paddock and Parkins bays the browns cruise slowly within a few metres of the shore. Stay out of the water, watch, and cast ahead of the fish on a long, fine leader of 15 ft or more. They feed on bullies, damselfly and dragonfly nymphs, midges and snails, and on cicadas, beetles and blowflies in summer. From late August the post-spawn browns patrol the stony margins for bullies. In autumn, trout and salmon gather off the Makarora and Matukituki deltas to feed on whitebait and native fish, best in March and April, and that is when most of the lake's salmon are caught at the Makarora mouth. Rainbows move to the river mouths in winter. Boat anglers troll lead line at 10 to 20 m, and Stevensons Arm is a quiet autumn spot where rainbows are the common catch. Fish & Game says someone takes a brown over 4.5 kg (10 lb) every few years, and a 12 kg (26 lb) brown trolled up in 2019 is thought to be the lake's biggest.
The lake is open all year to fly, spinner and bait, with a bag of 2 trout and 1 salmon, but fishing is closed off the Wānaka town front between the launch wharf and the marina jetty. The tributaries close in winter and have their own rules, so check the guide before you fish a river mouth upstream. The salmon fell away in the early 2000s while they held up in Hāwea and Wakatipu. Fish & Game found their first known spawning site, a Makarora tributary, only in 2023, and a second in the Wilkin catchment in 2026. The invasive weed lagarosiphon grows in the lake, and didymo is in the Makarora, so check, clean and dry your gear between waters.
