Cutbow Trout (Oncorhynchus clarkii × mykiss)

Body Type: A naturally occurring or hatchery-produced hybrid between Rainbow Trout and Cutthroat Trout. The Cutbow typically displays the red-orange jaw slash marks of the Cutthroat combined with the heavy spotting and pink lateral band of the Rainbow. Body shape is robust and similar to both parent species.

Preferred Water Temperature: 50°F–65°F. Inherits the cold-water preference of both parent species. Performs well in tailwaters and high-altitude lakes.

Habitat: Found naturally where Rainbow and Cutthroat Trout habitat overlaps — primarily in Rocky Mountain streams and rivers. Also stocked in Western lakes and reservoirs as a sport fish. Hybridization is a significant conservation concern as it threatens pure Cutthroat strains in native waters.

Best Lures: Inline spinners are highly effective. Small spoons produce in lakes. Fly fishing with dry flies and nymphs is the traditional approach. Small crankbaits work in rivers and lakes. Micro jigs produce in clear water.

Best Baits: Nightcrawlers work consistently year-round. Salmon eggs are effective in streams. PowerBait catches stocked fish in lakes. Wax worms produce in cold water.

Size & Weight: Typically 12–18 inches and 1–3 lbs. Grows faster than either parent species in some environments. Trophy Cutbow Trout reach 5–8 lbs in productive tailwaters.

Top 5 Places to Catch Cutbow Trout: 1. South Fork Snake River, Idaho — naturally occurring hybrids 2. Green River, Utah — tailwater below Flaming Gorge Dam 3. North Platte River, Wyoming — excellent wild hybrid population 4. Frying Pan River, Colorado — Gold Medal tailwater 5. Bighorn River, Montana — world-class tailwater fishery
