Re: Yellowstone Lake Thorofare
Best to check with the local fly shops and park officials if your heart is set on fishing the Thorofare Region. As Larry mentioned, the exploding Lake Trout population in Yellowstone Lake have devastated the lake's native Cutthroat population (along with all of the wildlife down the chain that relied on their spawning runs for food).
Matthews YNP fly fishing book tells of a Thorofare Region that sounds like the greatest Cutthroat Trout fishing experience one could find in North America, but that book was published around 2000. Schweber's book on the same subject (published about 10 years later) makes it sound like a dead zone... almost no trout, and gone as well are the animals that relied on them. It happened that fast (sadly).
The good news is that the Park has aggressively taken action to eliminate as many Lakers as possible over the last couple of years and numbers for Cutthroat showed a slight rebound in 2012.
