Lake Trout Identification Guide

Key identification features

• Robust, elongated body ranging from dark gray-green to olive or nearly black
• Numerous pale cream to whitish spots scattered over the body, head, and fins, with no red or orange spotting
• Deeply forked tail fin, more deeply notched than in brook or brown trout
• Fins often show a faint white leading edge, though less bold than in brook trout
• Can grow very large, with adults commonly exceeding 50 cm and some reaching well over a meter

Common look-alikes

• Brook trout: shares char ancestry but has red spots with pale blue halos and a much less forked, nearly square tail
• Splake (lake trout x brook trout hybrid): shows an intermediate tail shape and a mix of pale and pinkish spotting from both parent species
• Brown trout: has round black and red spots on a golden-brown body rather than uniform pale spots on dark gray

Where you'll see one

Inhabits deep, cold, well-oxygenated lakes across northern North America, typically staying in deep water during warmer months and moving shallower in spring and fall.
