There are certain lakes that stay with you.
Not just because of the fish, but because of the memories attached to them. The drive. The weather. The people. The feeling of arriving somewhere familiar after years away.
For me, Tunkwa Lake in British Columbia’s interior is one of those places.
The first time I fished Tunkwa Lake was back in February 2015, shortly after moving to British Columbia from California. New province, young family, unfamiliar waters, and endless curiosity about the legendary rainbow trout lakes scattered throughout BC’s interior.
Now, 11 years later, I found myself making that same drive once again.
From the green valleys of British Columbia’s Lower Mainland, over the snow-covered Coquihalla summit, and down into the dry rolling hills surrounding Tunkwa Lake Resort, it felt less like a fishing trip and more like returning to a place connected to an earlier chapter of life.
And almost immediately, the lake reminded us why anglers keep coming back.
Spring Rainbow Trout Fishing at Tunkwa Lake
Early spring can be one of the best times of year to fish rainbow trout in British Columbia’s interior lakes.
As water temperatures remain cool, rainbow trout cruise shallow shorelines aggressively feeding on leeches, freshwater shrimp, chironomids, damsels, and other food sources waking up after winter..jpg)
The conditions during our first afternoon were almost unbelievable for April.
Temperatures reached nearly 19°C. Fish were surfacing everywhere. Birds filled the shoreline. The lake felt alive.
I joined Rod from Fishing with Rod, and within moments of making our first casts, the action started.
The first trout hit while my spoon was still fluttering on the drop before I had even begun reeling.
That set the tone for the entire trip.
Why Spoons and Leech Patterns Worked
One of the most interesting patterns we observed during this trip was how aggressive the trout were toward falling presentations.
Fluttering spoons, micro jigs, and slowly moving leech patterns consistently triggered strikes.
Many fish hit on the drop itself.
At times, trout were visibly cruising ridge edges and shallow transitions just a few feet below the surface. Reading those underwater contours became one of the keys to finding actively feeding fish.
As the days progressed, we experimented with:
- spoons
- pumpkin leech patterns
- black and red micro leeches
- float fishing techniques
- twitch retrieves
- fly fishing presentations
The trout responded differently depending on light levels, wind, and water clarity.
And then things got even more interesting.
Underwater Trout Footage with the SHINE CAM SC100
One of the highlights of this trip was testing the SHINE CAM SC100 underwater fishing camera.
Honestly, I was not prepared for how fascinating the footage would become.
For years, anglers imagine what trout are doing beneath the surface:
- following lures
- inspecting flies
- refusing presentations
- suddenly committing to a strike
But watching it happen underwater in real time completely changes your understanding of fish behavior.
The underwater footage revealed:
- how rainbow trout approached spoons
- hesitation behavior before strikes
- reaction distances
- competitive feeding behavior
- how water clarity changed fish movement
- how trout positioned themselves in shallow structure
For someone deeply interested in fish behavior and trout fishing strategy, it was one of the most educational experiences I’ve had on the water.
Day Three: Surviving Extreme Wind on Tunkwa Lake
British Columbia spring weather can change fast.
Very fast.

By day three, the calm conditions were gone and replaced with brutal wind gusts reaching 50 to 60 km/h across the lake.
Anchoring became nearly impossible.
Every time we set anchor, the boat would get blown off position within minutes.
But the trout were still jumping.
So naturally, instead of making intelligent life choices, we improvised.
We spotted a massive shoreline rock, looped a rope around it, backed the boat out roughly 50 feet, and pinned ourselves into position using a second anchor.
And somehow…
it worked perfectly.
Almost instantly after stabilizing the boat, the trout bite turned back on.
Sometimes fishing success comes from advanced strategy.
Sometimes it comes from tying yourself to geological formations and hoping physics cooperates.
Trout Behavior, Wildlife & BC Interior Beauty
Beyond the fishing itself, one of the most memorable parts of the trip was simply experiencing spring in British Columbia’s interior.
Every morning the lake came alive with:
- geese
- ducks
- loons
- cranes
- songbirds
- rising trout
The contrast between snowy mountain peaks and dry interior grasslands created incredible scenery throughout the trip.
Even during slower fishing periods, the environment itself made every moment worthwhile.
That’s one of the reasons Tunkwa Lake remains such a special destination for trout anglers across British Columbia.
Logan Lake Spawning Channel
Before heading home, we made one final stop at Logan Lake’s spawning channel.
Every spring, wild rainbow trout move into the channel to spawn, creating one of the most incredible wildlife experiences available to freshwater anglers in British Columbia.
Laying quietly beside the stream and watching these fish battle for position in crystal-clear water was a powerful reminder that trout fishing is about far more than simply catching fish.
It is about understanding ecosystems, seasons, migration, and the natural rhythms that drive these lakes year after year.
Final Thoughts
This trip reminded me why I fell in love with fishing British Columbia’s interior lakes in the first place.
The changing weather.
The friendships.
The experimentation.
The underwater discoveries.
The challenge.
The beauty of wild places.
And of course, the incredible rainbow trout.
Huge thanks to Tunkwa Lake Resort for hosting us during this adventure and to SHINE CAM for providing the SC100 underwater camera that captured a perspective most anglers never get to see.
