Brook trout are an introduced fish species that were first stocked in the early 1900s. While technically not a trout (they are a member of the char family), their life history, ecology and habitat are similar to brown and rainbow trout. Brook trout are widely distributed from high mountain lakes to headwater tributaries. They are the most prevalent game fish in both wilderness and non-wilderness high lakes. In small streams and high lakes brook trout are typically small – 5- to-7 inches long. In larger streams and rivers they can reach more than
25 inches.
Because insect larvae and nymphs make up a large part of their diet, they are a favorite target of fly fishers who use flies mimicking these insects. However, these aggressive biters will also go after a variety of other baits and lures.
