This is the main lake in Yellowstone but has little fishing pressure due to the abundance of trophy class streams and rivers. The native cut-throat trout grow large here. Quality fly fishing for cutthroat trout can be obtained fishing from the shoreline even though there are over 87,000 acres of lake.
If you use a boat or float tube, make sure you be aware that strong winds can blow here.

The cut-throat will jump 6 feet to chase a Callibaetis imitation. There is a KILL ALL rule for any Laketrout that you catch. Cutthroat are Catch and Release only.
