Greenstone follows at 12 km, then Longlac at 34 km. There is no boundary nearby to worry about.

• Where to Fish on Dionne Lake

  Nothing we hold settles how deep this runs. A soft bed grows weed late into autumn, which keeps fish shallow. On a natural lake the weed line and the shelf beyond it do the work. Records held for Thunder Bay District cover cisco, blackfin cisco, rainbow smelt and bloater. County records show what lives in the area; the local agency holds the water-by-water list. The shape of Dionne Lake decides where the fish sit.

• Seasonal Patterns

  July is the warm end of the year here, averaging about 16°C, while January sits near -20°C. Open water is the exception rather than the rule here. The lid usually sets by midwinter and gives way around early May. The season between ice runs from about early May to mid November. Late spring and early autumn carry the year between them. Time your trip to Dionne Lake by conditions rather than dates.

• Tackle & Baits

  The paperwork position is blank for this one. This is a natural basin, not a dammed one. We find no slipway, car park or made path within a short radius, so treat access as rough. Keep the gear simple: light line, small hooks, split shot and a couple of proven lures. Local rules can differ across the county line, so check where you stand. Some ground is open by custom rather than by right, so tread carefully. If the gate is shut, Quintuplet Lake at 1.7 km is the nearest alternative. Check the position on Dionne Lake before loading the car.
