Dumont Lake near Greenstone: Fishing Spots, Seasons and Access

• Overview

  In Ontario, Dumont Lake falls inside Thunder Bay District. The surroundings are spruce and muskeg. With some 20 hectares of water, there is room for a boat but no need of one. Around 2.3 km of margin, front to back. Start from Greenstone, 32 km down the road. It is 186 km to Thunder Bay, the nearest city. The nearest edge is a long way off, so local rules apply throughout.

• Where to Fish on Dumont Lake

  No depth figure appears in our records, so the bank has to tell you. Still water like this holds fish on the edges rather than out in the open. On a natural lake the weed line and the shelf beyond it do the work. Public occurrence data for Thunder Bay District names cisco, blackfin cisco, rainbow smelt, bloater and shortjaw cisco. County records show the wider picture rather than this one place. Dumont Lake repays a walk before the first cast.

• Seasonal Patterns

  Expect July near 16°C and January near -20°C on the long-run figures. A short, intense season is the rule this far north. Firm cover through the cold months, then open water from early May. Expect the water usable from around early May until roughly mid November. Early summer and early autumn carry the open-water season. Time your trip to Dumont Lake by conditions rather than dates.

• Tackle & Baits

  Whether you may fish here is not something records settle. It formed naturally, so levels move with rainfall rather than with a gate. 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. Season dates differ by species, so read the table. Barbless rules turn up on managed water more often than not. Clist Lake, 1.8 km away, makes the obvious fallback. Confirm access to Dumont Lake locally before you travel.
