The 5 primary trouts are the rainbow, brook, brown, cutthroat and
lake trout. Brown trout are considered the most difficult to catch
and brookies are the easiest. Pure cold water is key to survival
of the trouts and the brook trout is the most sensitive to temperature.
The others are comfortable in slightly warmer waters.
