Introduced warmwater sportfish established in select lakes and slow river channels around
Creston and the East Kootenays, with explosive strikes on surface patterns. Key largemouth
bass fisheries are Duck Lake inside the Creston
Valley Wildlife Management Area (CVWMA), Suzanne
Lake, and the backwaters and wetlands of the
Kootenay River and Columbia Lake. Fly
anglers strip surface poppers and foam frogs along weed edges, or fish large streamers in
the pockets. Note the access rule: angling for bass in Duck Lake and connected wetlands
requires a specialized CVWMA fishing permit in addition to a standard BC freshwater licence.
Region 4 rules. Regional default daily quota is
0 (CLOSED). Duck Lake is 3 daily (only 1 over 40 cm) from June 16 to May 14, and
catch-and-release only from May 15 to June 15 to protect spawning fish. Unlimited quotas
apply in Columbia Lake, Suzanne Lake, and most other CVWMA waters (Leach Lake, Six Mile,
Canal) to suppress spread and protect native salmonids.
An invasive apex predator posing a severe threat to native salmonids in the Columbia Basin,
feeding heavily on westslope cutthroat, rainbow, and juvenile bull trout. Northern pike hold
in slow, weedy backwaters, sloughs, and connected floodplains, found in the lower connected
reaches of the Kootenay River. Target them
with large wire-leader rigs — flash streamers, spoons, and topwater walk-the-dog lures.
Region 4 rules. Regional default is 0 (CLOSED) to
discourage transport and illegal introduction. In the lower connected reach of the Kootenay
River (downstream of Brilliant Dam to the Columbia), daily quotas are unlimited to encourage
maximum angler harvest and suppression.
Introduced predatory sportfish localized in the tailwater reaches of the Columbia and
Kootenay rivers, prized as table fare and managed under high harvest quotas to reduce
pressure on native salmonids. Walleye are confined primarily to the lower
Columbia River (downstream of Hugh
Keenleyside Dam to the US border) and the lower
Kootenay River (downstream of Brilliant
Dam to its Columbia confluence). Nocturnal hunters — fish jig heads tipped with soft
plastics or bait, or slow-troll crankbaits along gravel bars, current seams, and deep runs.
Region 4 rules. Regional default is 0 (CLOSED) to
prevent illegal introduction into new waters. Daily quota is 16 walleye in the Columbia River
(Keenleyside to the Washington border) and the Kootenay River (Brilliant Dam to the Columbia
confluence) to encourage harvest and suppress abundance.
Introduced warmwater panfish, considered an invasive threat in native salmonid waters but a
popular fishery in warmwater systems. Yellow perch are established in
Duck Lake and connected CVWMA waters, as well
as parts of Kootenay Lake. Take them on
light tackle or fly rods with small baitfish streamers, nymphs, or wet flies near submerged
structure and weed lines.
Region 4 rules. Regional default is 0 (CLOSED) to
prevent illegal stocking and spread. Duck Lake is 20 daily. Unlimited daily limits are active
on Kootenay Lake (all parts) and connected CVWMA channels (Six Mile, Leach Lake) to encourage
harvest and control populations.
The only freshwater cod (locally lingcod or lawyer), native to deep, cold lakes and large
river corridors of the Columbia Basin, and prized eating. Burbot are found in
Kootenay Lake, the
Kootenay River, the
Columbia River,
Duncan Lake,
Moyie Lake, and Columbia Lake. Target them in
winter or at night with heavy jigs tipped with bait fished on the bottom.
Region 4 rules. Default regional daily quota is 2
burbot. Burbot are strictly catch-and-release in Kootenay Lake (all parts), the Kootenay River
(US border to Kootenay Lake), the Columbia River, Columbia Lake, and
Windermere Creek. Moyie Lake has a burbot
catch-and-release conservation window from February 14 to 28 to protect spawning aggregations.
A native salmonid widely distributed across the region's large rivers, holding in deep pools
and swift runs alongside trout and offering excellent winter nymphing. Mountain whitefish are
abundant in the Columbia,
Kootenay,
Elk, and
Duncan rivers. Fish high-density nymphing near
the bottom with small #14–18 bead-head Pheasant Tails, Hare's Ears, or brassies — they school
in deep pools, so one fish usually means several.
Region 4 rules. Regional daily default is 15
whitefish. Subject to the default stream closures (April 1 to June 14) and bait bans where active.
An endangered native prehistoric giant of the Kootenay and Columbia systems — North America's
largest freshwater fish — and strictly closed to all sport targeting in the region. Dam
operations altered flows and temperatures, causing severe recruitment failure; the Kootenai
River population is critically endangered and maintained through conservation hatcheries. White
sturgeon historically ranged throughout
Kootenay Lake, the
Kootenay River, and the
Columbia River corridors.
Region 4 rules. The daily quota for sturgeon is 0
(CLOSED) across all regional waters. Targeting sturgeon is illegal, and any accidental catch
must be released immediately without removing the fish from the water.
All of the above are as the region's species notes record them. Closures, exceptions, and
suppression reaches change — always confirm the current status against the official BC freshwater
regulations synopsis, and see daily limits and
harvest rules for the mechanics.
