12,931-acre lake in Kenora District, Ontario. The lake tops out around 160 ft. The depth data here comes from the Ontario MNRF survey of 1972, a decades-old survey (a transect sounding survey). Here is how the season plays out for each species, straight from the data behind the map.
Mameigwess Lake maps at 12,988 acres behind 53.7 miles of shoreline — 16 islands included. With a shoreline index of 3.4, this water is all arms and coves — edge habitat well beyond its acreage. Littoral water — the productive band under ~15 ft — makes up 18% of this chart. Call it 9.1 mi long by 5.3 mi wide at the broadest reach. Kenora District claims this one. If the bite dies, Mud Lake is 4 mi to the west.
Spring lake trout on Mameigwess Lake hold shallow, usually 10 to 40 ft. They move out to 50 to 120 ft in summer and finish the year down in 20 to 80 ft. Put Rock reef first on the milk run — a rock pile near 9 ft that grades prime for fall. The feeding windows run early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.

|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Secondary point (18 ft) | Casting spoon over shoals, Jerkbait (shallow) |

Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.

You won't need more than a blade bait vertical or a small jigging spoon most summer days.
