How to fish it · for Rainbow
When
No strong hatch signals at the moment — general searching tactics should work best. The ripple is helpful — fish should move onto the feed and a slow-drifted team or single wet will cover water well.
Where
Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. When no hatch is visible, a buzzer team — black stripped quill on the point, attractor or pearl-rib on the top dropper — is the default starting point on any UK stillwater.
The plan
Plan A

Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. When no hatch is visible, a buzzer team — black stripped quill on the point, attractor or pearl-rib on the top dropper — is the default starting point on any UK stillwater.

Plan B

If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.

Watch for

Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.

Boat — drift

A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.

About this water

Lake Rotoiti is one of the best of the Rotorua lakes — deep, scenic and joined to Lake Rotorua by the famous Ohau Channel, where fish stack and the fishing can be exceptional. It grows strong rainbows and browns, fished by trolling and jigging the drop-offs, working the channel mouth and stream mouths, and fly fishing the cold-water inflows. A fine all-round Bay of Plenty lake fished much like Tarawera and Rotorua.

Under the surface

Lake Rotoiti lies just east of Rotorua in the geothermal Bay of Plenty, a deep, irregular caldera lake of bush-fringed bays and hot-water shores, joined to Lake Rotorua by the Ohau Channel. Cooler and deeper than its neighbour, it grows strong rainbows and browns that gather at the Ohau Channel mouth and the cold-water inflows. (Not to be confused with the Nelson Lakes Lake Rotoiti at the head of the Buller.)

Wading: Deep cold lake, geothermal areas, sudden weather — boat/shore

Hatches & food

Peer-reviewed diet analysis found smelt supply nearly four-fifths of adult trout diet here by weight, alongside koura, bullies and koaro — chironomids, small caddis and terrestrial insects matter mainly to juvenile fish under 200mm. This is a baitfish lake, not an insect-hatch one, for anything worth targeting.
