Big Marsh Lake Fishing in Algoma, Ontario

• Overview

  Look for Big Marsh Lake in the Algoma part of Ontario. It lies 401 metres above sea level. With some 29 hectares of water, there is room for a boat but no need of one.

There is no boundary nearby to worry about.

• Where to Fish on Big Marsh Lake

  Depth figures are not published for this one. The productive water is a rod length or two out, not a hundred. Where the bottom changes texture, fish gather; find that line. Fish documented in Algoma include walleye, northern pike and Iowa darter. County records show what lives in the area; the local agency holds the water-by-water list. Work Big Marsh Lake in sections rather than trying to cover it.

• Seasonal Patterns

  Average temperature peaks around 16°C in July and bottoms out near -16°C in January. The freeze holds for the better part of the year. The freeze runs deep into the year, with break-up near early May. Open water usually runs from early May until about 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 Big Marsh Lake.

• Tackle & Baits

  There is no clear statement anywhere on who can fish it. It formed naturally, so levels move with rainfall rather than with a gate. Mapping is blank for access, so scout the approach before committing the car. Check locally before you travel, because a wasted drive is a long one. Rules for boats are stricter than rules for the bank in many places. If the gate is shut, Radford Lake at 2.3 km is the nearest alternative. What applies at Big Marsh Lake may have changed since it was mapped.
