• Where to Fish on Dumas Lake

  There is no published depth for this one, so start shallow and work out. The shallow end warms first and pulls fish in ahead of the rest. A soft bed grows weed late into autumn, which keeps fish shallow. Across Thunder Bay District, recorded fish include cisco, blackfin cisco, rainbow smelt and bloater. The list covers the county rather than this water alone, so treat it as a guide. The shape of Dumas Lake decides where the fish sit.

• Seasonal Patterns

  The range across the year is -20°C to 16°C. Open water is the exception rather than the rule here. Ice is part of the season here, ending near early May. The lid tends to go about early May and return around mid November. The open run goes from the thaw to the freeze, and April through October covers most of it. It sets the rhythm of the year at Dumas Lake.

• Tackle & Baits

  Public data does not answer the access question here. It formed naturally, so levels move with rainfall rather than with a gate. Nothing built is recorded close to the bank here. Keep the gear simple: light line, small hooks, split shot and a couple of proven lures. A landowner's word beats anything printed elsewhere. Keep proof of licence with you rather than in the car.
