When to fish lake trout in Idaho
- Spring 10–40 ft — The brief shallow window: post-ice-out lakers roam rock shoals and points where anyone can reach them.
- Summer 50–120 ft — Below the thermocline in sub-50°F water — deep humps and basin edges near bait (smelt, cisco, alewife).
- Fall 10–50 ft — Turnover puts lakers on shallow rock reefs to spawn — big fish shallow, best late in the day.
- Winter 20–80 ft — One of the best ice targets — cold water is their comfort zone; they roam basin edges and humps all winter.
