Brook Trout are not as common as they once were on Boulder Mountain, with the Fish & Game leaning more towards the native cutthroat species of the area.
However, there are still a few trophy Brook Trout waters on Boulder Mountain, and a few waters with 12-14″ Brook Trout, many of the Brook Trout being stocked now are referred to as Muleys, because they are a triploid and dont have the capability to reproduce.
If you are targeting record size or personal best Brook Trout, come prepared for a good hike, typically early or late in the season, and plenty ofpatience.
