Primary Species
Seasonal Tips
Winter: prime time for Gerrards — surface-troll plugs and flies on long lines through the cold months, when the giants feed high in the water column. Spring: bull trout stack near tributary mouths as runoff builds. Summer: fish go deep midweek-quiet mornings; downrig the main-lake drop-offs. Fall: kokanee spawn draws everything toward the north end — respect the closures around the Lardeau and Meadow Creek.
About This Place
Kootenay Lake, pinned between the Selkirk and Purcell ranges in BC's deep southeast, is famous for one thing above all: Gerrard rainbow trout, the largest-growing strain of rainbow on Earth, which spawn in a single short stretch of the Lardeau River at the lake's north end. These fish feed on kokanee in open water and have been caught at weights most anglers associate with salmon — the reason winter trolling here draws anglers from across the continent. Bull trout, the lake's native char, share the same forage and the same trolling lines.
It's big, moody water: 100-plus kilometres of main lake plus the shallower West Arm at Nelson, crossed at Balfour by the longest free ferry ride in the world. The fishery's fortunes track the kokanee forage base, which collapsed in the 2010s and has been the focus of intensive recovery work — regulations have shifted with it, including closures on the West Arm kokanee, so current rules matter here more than most places. BC freshwater licence required.

Best Time to Visit
Spring (May-June): Post-ice-out is prime time for Lake Trout. Water temperatures are ideal and fish are actively feeding after the long winter.
Summer (July-August): Switch to early morning and late evening bites. Deep water trolling produces best results.
Fall (September-October): Arguably the best season — cooler water triggers aggressive feeding. Fewer crowds and excellent catch rates.
Winter: Limited winter access. Check road conditions before heading out.
Terrain & Topography
A 100-plus-kilometre trench between the Selkirk and Purcell ranges, deep and steep-walled, with the shallower West Arm at Nelson and tributary deltas — Lardeau country north — that rule the fishery's fortunes.
Regulations & Permits
