i think well be seeing more and more tigers in the future. at least here in minnesota. im sure wis. isnt much different but having never fished it i cant say.
it seems to me that here in mn. since the 07 floods streams are flowing faster and cooler than they were before the flood. in 2008 i caught a brookie in a stream that dosnt hold brookies. it was also caught right where a spring runs into the stream. ive walked the spring for a short distance in the past but never saw any fish. that dosnt mean they werent in there though.
in 2009 i caught a bunch of brookies the same morning in a stream that isnt know for holding them. there are a few feeder streams known for brookies but this was quite a distance from any of them. again they prob washed out in a flood and again there were a few springs within a relatively short distance of where i was catching them. this goes to show that the quality of our streams is improving and its only a mater of time before a male brookie fertilizes a female browns eggs.
