Mar Lake Fishing near Greenstone, Ontario

• Overview

  Mar Lake lies in Thunder Bay District, Ontario. The setting is boreal forest on every side. At about 68 hectares, a day is enough to walk the shoreline properly. The whole outline is near 4.8 km, and most of it is walkable. Start from Greenstone, 4.4 km down the road. After that come Geraldton at 20 km and Longlac at 50 km. It lies deep inside the county rather than near an edge.

• Where to Fish on Mar Lake

  Depth is unknown to us, and the shoreline is the better guide. Still water like this holds fish on the edges rather than out in the open. A natural lake fishes on cover, and cover here means weed and timber. Thunder Bay District records list cisco, blackfin cisco and rainbow smelt among the fish reported. Read it as a county summary, not a water-by-water list. Mar Lake responds to conditions more than to tactics.

• Seasonal Patterns

  Climate records put July near 16°C and January near -19°C. Water stays cold even at the height of the year. Count on hard cover from midwinter, and open water from early May. Climate averages put the opening at about early May and the closing near mid November. The strong weeks are the first after break-up and the last before the freeze. It sets the rhythm of the year at Mar Lake.

• Tackle & Baits

  We hold no note on access for this one. Records list it as a natural water body rather than an impoundment. Mapping shows no built access close by; expect to walk in from wherever you can leave the car. Keep the gear simple: light line, small hooks, split shot and a couple of proven lures. Take the rules with you rather than trusting memory. Night access is frequently treated as a separate matter. For a change of water, Scroll Lake is 1.3 km distant.
