You won't find a larger rainbow trout, anywhere

Each spring the public can view the Gerrard rainbow trout, the largest rainbow trout in the world, as it returns to the Lardeau River to spawn.

Test your fish facts

Getting there

To reach the viewing platform from Kaslo, take highway #31 towards Meadow Creek. From Meadow Creek stay on highway #31 (well-maintained gravel road) until you cross the bridge over the Lardeau River near the outlet of Trout Lake (approx. 45 minutes from Meadow Creek). The viewing platform and parking area is to the right of the road after the bridge.

Test your fish facts:

  1. True or False: The Gerrard rainbow trout is the largest type of rainbow trout on earth?
  2. Why are they called Gerrard rainbow trout?
  3. Can you fish for Gerrards in the Lardeau River?
  4. Where do they spawn?
  5. What is the Gerrard run like now? (the number of fish spawning)


  1. True. The largest sport-caught rainbow from Kootenay Lake was 16 kilograms (35.5 pounds) and was hooked in 1976. Gerrard rainbow trout consistently reach sizes in excess of 10 kg (22 pounds).
  2. The fish are named after the post office and settlement of Gerrard which was the end of the CPR railway line. George Bentley Gerrard was a bank manager in Kaslo in the 1900s.
  3. No. The wild, pristine Lardeau River and its tributaries provide important habitat for adults and young fish. It has been closed to fishing since the 1940s and remains closed, except for a short springtime whitefish fishery. Over fishing was a factor in their decline in the 1950s.
  4. The majority of the unique Gerrard rainbow trout spawn at the Gerrard site on the Lardeau River.
  5. In the mid-1950s the Gerrard run was down to less than 150 fish. Today, thanks to fishing regulations and the addition of nutrients to the north arm of Kootenay Lake by the Fish & Wildlife Compensation Program and the Ministry of Environment, the Gerrard run is approximately 1,000 fish / year.
