601-acre lake in Thunder Bay District, Ontario. The lake tops out around 100 ft. The depth data here comes from the Ontario MNRF survey of 1970, a decades-old survey (a transect sounding survey). What the data behind the map says about each species, season by season:
On the chart, Katzenbach Lake draws 604 acres inside 7.7 miles of shoreline — 10 islands included. That shoreline is heavily fingered (development index 2.2) — bays, points and pockets everywhere, which multiplies the fishable edge. The shallow band under 15 ft claims about 24% of the surface — that's where the groceries are. Tip to tip the water measures near 1.9 mi with a 1-mi widest point. You'll find it in Thunder Bay District. The nearest mapped water is Mishi Lake, 1 mi to the northwest.
Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Warm water sends them out to 30 to 100 ft; cold water stacks them in 20 to 80 ft. Top water on the chart: Deep basin, a deep basin in the 100 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a white tube jig (deep) or a magnum spoon on downrigger until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (10 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 30 to 100 ft | dawn | Deep basin (100 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Break off the point (10 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (10 ft) | White tube jig, Airplane jig |
When the water first warms, cisco (lake herring) slide up into 10 to 40 ft. Summer is a 40 to 80 ft game here, winter a 20 to 60 ft one. Start at Break off the point. It's a drop-off holding about 10 ft of water and rates good come spring. The feeding windows run early morning. Keep a vertical flutter spoon (small) or a drop-shot micro plastic rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (10 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 40 to 80 ft | dawn | Deep basin (100 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (10 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Deep basin (100 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
