• Where to Fish on Agonzon Lake

  No depth figure has reached our records, which makes a plummet useful. The productive water is a rod length or two out, not a hundred. Still water like this holds fish on the edges rather than out in the open. Reported across Thunder Bay District: cisco, blackfin cisco and rainbow smelt. County records show what lives in the area; the local agency holds the water-by-water list. Fish Agonzon Lake where the bottom changes rather than where it looks deep.

• Seasonal Patterns

  Averages here run 16°C at the top of summer and -17°C at the bottom of winter. Winter runs most of the calendar, and everything worth doing happens in the gap. Hard cover is dependable here; it goes around early May. The water is typically free of ice between early May and mid November. Look to early summer and the first cool weeks of autumn. It sets the rhythm of the year at Agonzon Lake.

• Tackle & Baits

  The paperwork position is blank for this one. It formed naturally, so levels move with rainfall rather than with a gate. Formal access is not mapped, so the last stretch is likely on foot. A light spinning outfit with a small box of lures and some bait covers most of what swims here. Rules for this water may differ from the county norm. Barbless rules turn up on managed water more often than not. Billet Lake at 3.5 km is the sensible second choice. For Agonzon Lake, the notice at the access point is the final word.
