Fishing at Mona Lake, Thunder Bay District, Ontario

• Overview

  Mona Lake is a Thunder Bay District water, in Ontario. It lies 386 metres above sea level. Around 26 hectares of surface means several distinct areas to work. The whole outline is near 2.9 km, and most of it is walkable. Nearest town is Nipigon, 54 km off. Thunder Bay sits 78 km out, and it is the nearest city worth the name. No county line comes close, which keeps the paperwork simple.

• Where to Fish on Mona Lake

  Depth is not on record here, so the bank has to tell you. This is a lake, so the margins and the first drop matter most. Weed, then depth: that is the order to fish a water of this kind. Across Thunder Bay District, recorded fish include cisco, blackfin cisco and rainbow smelt. Records at this level tell you what is in the area. Anyone new to Mona Lake should walk it once before setting up.

• Seasonal Patterns

  Averages here run 17°C at the top of summer and -18°C at the bottom of winter. The ice season is long here and the open one short. After early May the shallows warm and the fish move up. Expect the water usable from around early May until roughly mid November. Spring is short and heavy here; autumn is longer and steadier. It sets the rhythm of the year at Mona Lake.

• Tackle & Baits

  We hold no note on access for this one. No dam controls it, and the level follows the season. Public data shows nothing built here, so treat the whole approach as informal. A light spinning outfit with a small box of lures and some bait covers most of what swims here. Ask in the nearest town if you are unsure. Signs go up and come down, so check on the day. Leckie Lake at 2 km is the sensible second choice. Check the position at Mona Lake before loading the car.
