Rainbows are the most widely stocked and distributed trout in many regions. They occur naturally in many rivers and streams and are stocked in ponds and lakes. They are highly variable in color, often silvery, with light pink to red stripe along sides. The can reach up to 30 inches in length. Rainbow trout prefer cold, clear water and are most often found in water 45-60 degrees Fahrenheit.

Their diet consists of minnows, crayfish, insects, and other small aquatic life, making them susceptible to a well-presented spinner, flatfish or fly.
