Fall Fishing in Yellowknife: Arctic Char and Lake Trout in September

What's biting

  • Arctic Char

    Where: Shallow bays and creek mouths of Yellowknife Bay and Dettah Lake; moving into deeper water as surface temps drop.

    Use small spinners (size 1–2), spoons, or live minnows in 2–5 m (6–16 ft) of water. Early morning and dusk are most productive; char are feeding heavily before freeze-up.

    Caution: Handle carefully—sharp gill plates. Verify slot limits and minimum size with the regulator before keeping any fish.

  • Lake Trout

    Where: Deeper structure in Yellowknife Bay, around submerged rock piles and drop-offs; also accessible from Dettah Lake's main basin.

    Fish 8–15 m (26–50 ft) with jigging spoons or small tube jigs; vertical jigging is most effective this time of year. Slow presentations work best in cooling water.

    Caution: Lake trout are slow-growing in the Arctic; consider catch-and-release to preserve populations.

  • Northern Pike

    Where: Weedy shallows and bay margins of Yellowknife Bay; pike remain active in fall but are less predictable than char.

    Cast larger spinners (size 3–4) or soft plastics along vegetation edges in 1–3 m (3–10 ft) of water. Retrieve steadily or use a stop-and-go pattern.

    Caution: Pike have sharp teeth; use a steel leader or bite tippet to avoid line breakage.

  • Whitefish (Broad Whitefish & Arctic Cisco)

    Where: Open water of Yellowknife Bay and Dettah Lake; often schooling in mid-water column.

    Use small jigs (1–3 g / 0.04–0.1 oz) tipped with maggots or small minnow pieces. These fish are abundant but require patience and light tackle.

    Caution: Whitefish are excellent eating but small; check regulations for any species-specific guidance.

Best times

Early morning and dusk through mid-September; fish actively before water temperature drops further. Expect frost by late September (typically around Sep 25), so plan trips accordingly. Waning crescent moon (Sep 8–11) favors low-light periods.

Waters to try

  • Yellowknife Bay, Dettah Lake, Mackenzie River (lower reaches near Yellowknife)
