How to fish it · for Rainbow
When
Ice-off (May) and autumn.
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.
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.

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

Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.

Boat — drift

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

About this water

Stump Lake is a big, productive lower-elevation lake in the Nicola valley that grows strong rainbows. Larger and windier than the small fly lakes, it suits shoal chironomid fishing and stripped-fly tactics from a boat, with the chance of a sizeable fish. Watch the weather on this open water.

Under the surface

Stump Lake is a large, lower-elevation alkaline lake in the Nicola valley between Kamloops and Merritt, productive and capable of growing big rainbows. Bigger and more weather-exposed than the small fly lakes, it offers shoal fishing and trolling-style fly tactics for strong fish in a broad valley setting.
