I talked to Quetico Dave about this. He said he had heard the same-thing but didn't know anyone who had actually caught any?

I checked all my maps and Ontario fish on-line and they show Brook Trout in lakes north of Hw 11.

Another native Brook Trout range map shows they should be there?

I see plenty of streams on the NW corner entering Batch. If there are BT there, that's where I would try.

  IMHO nothing is better than BT fried in a little oil with some eggs and spuds for a meal.
