Demuth Lake, Ontario: Fishing Spots and Seasons

• Overview

  Ontario holds Demuth Lake, in Thunder Bay District. Northern bush runs right down to the water. Surface area runs to about 3 hectares — small enough to read in one session. It is one of the smaller waters we list in Thunder Bay District. Start from Amethyst Harbour, 24 km down the road. For a city, Thunder Bay is 55 km off. The county line is nowhere near, so one local authority covers the water.

• Where to Fish on Demuth Lake

  We hold no survey for this water; read the slope of the shoreline instead. The shallow end warms first and pulls fish in ahead of the rest. This is a lake, so the margins and the first drop matter most. Across Thunder Bay District, recorded fish include cisco, blackfin cisco and rainbow smelt. Those are county-wide records, so not every one of them will be in this water. Demuth Lake repays a walk before the first cast.

• Seasonal Patterns

  Averages move between -16°C in January and 17°C in July. Cold dominates the calendar on water this far north. The lid arrives early and lasts until roughly early May. Averages suggest open water from about early May through to roughly mid November. Fish feed hardest at the start and the close of the open season. At Demuth Lake the season follows that pattern closely.

• Tackle & Baits

  Who may fish here is not settled in anything we hold. Mapping shows an empty shoreline: no ramp, no jetty, no marked entry. Keep the gear simple: light line, small hooks, split shot and a couple of proven lures. Parking space is the usual limit rather than the bank itself. Some ground is open by custom rather than by right, so tread carefully. Should this one be busy, Bigger Lake is 0.7 km off. Ask locally about Demuth Lake if anything is unclear.
