I want to know the answer to the following question:
Since when has Montana been a destination for trout fisheries?
All the background I'm provided with is that "The state has robust recreational lake trout and kokanee salmon fisheries in the west, walleye can be found in many parts of the state, while northern pike, smallmouth and largemouth bass fisheries as well as catfish and paddlefish can be found in the waters of eastern Montana.". Is that enough to answer the question?
Answer: no
