When to fish cutthroat trout in Idaho
- Spring 3–15 ft — Pre- and post-spawn cutthroat gang up at tributary mouths and cruise gravel shorelines — swing a spinner or fly through the inlet current.
- Summer 10–35 ft — Summer cutthroat hold along the first shoreline drop and off rocky points, sliding deeper as the surface warms — troll or cast the 15-30 ft edge.
- Fall 5–25 ft — Cooling water brings cutthroat back onto rocky points and gravel shoals to feed hard before winter.
- Winter 10–40 ft — Cold-tolerant like all trout — cutthroat hang on the deep shoreline drops and basin edges through the cold months.
