1,353-acre lake in Rainy River District, Ontario. The lake tops out around 276 ft. The depth data here comes from an MNRF lake survey by the Ontario MNRF. Species by species, here's what the data says the year looks like.
On the chart, Kahshahpiwi Lake draws 1,359 acres inside 31.2 miles of shoreline — 31 islands included. That shoreline is heavily fingered (development index 6) — bays, points and pockets everywhere, which multiplies the fishable edge. About 16% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 5.6 mi, about 1.3 mi across. You'll find it in Rainy River District. Closest neighbour on DepthScout: Burt Lake, 5 mi northwest of here.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 50 to 120 ft before dropping to 20 to 80 ft for winter. Spring lake trout concentrate at Main-lake point, a prime-rated point around 16 ft. Fish it in early morning and you'll meet the bite. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.

The summer box starts with a blade bait vertical or a small jigging spoon.

When the water first warms, walleye slide up into 4 to 15 ft. By summer they slide out to 15 to 35 ft, and by winter most fish are in 20 to 40 ft. If you only fish one area, make it Main-lake point: a point around 16 ft that scores prime in fall. In summer the feeding windows fall in the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.
