Little Trewartha Lake Fishing Guide, Thunder Bay District, Ontario

The nearest boundary is a fair way off.

• Where to Fish on Little Trewartha Lake

  No depth figure appears in our records, so the bank has to tell you. A soft bed grows weed late into autumn, which keeps fish shallow. Read the surface for the wind lane, then fish the edge of it. Across Thunder Bay District, recorded fish include cisco, blackfin cisco and rainbow smelt. County records show what lives in the area; the local agency holds the water-by-water list. On Little Trewartha Lake a short move beats a long cast.

• Seasonal Patterns

  Long-run averages give July about 17°C and January about -19°C. Cold winters and warm summers give a wide working range. Winter fishing happens on the ice here, with open water back around early May. Break-up near early May, freeze-up near mid November: that is the shape of an average year. May into June fishes hardest, and September gives a second good stretch before the lid returns. Little Trewartha Lake runs to that rhythm year in and year out.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. 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. One rod, a handful of hooks and floats, and a few small lures are enough for this water. Ask in the nearest town if you are unsure. Some stretches are reserved and marked as such on the ground. For a change of water, Antler Lake is 5.4 km distant. Confirm access to Little Trewartha Lake locally before you travel.
