101-acre lake in Thunder Bay District, Ontario. The lake tops out around 39 ft. The depth data here comes from the Ontario MNRF survey of 1978, 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.
On the chart, Cliff Lake draws 101 acres inside 1.9 miles of shoreline. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. About 35% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 0.7 mi long by 0.4 mi wide at the broadest reach. The water lies in Thunder Bay District. Closest neighbour on DepthScout: Pringle Lake, 1 mi northeast of here.
Start shallow in spring: lake trout sit in 10 to 39 ft that time of year. They don't go far with the seasons — 12 to 39 ft covers summer, 10 to 39 ft covers winter. The spot to know is Deep basin, a deep basin in about 39 ft of water that rates prime for lake trout in summer. Warm-month bites cluster around early morning. 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 39 ft | dawn & dusk | Main-lake point (12 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 12 to 39 ft | dawn | Deep basin (39 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 8 to 39 ft | dusk & dawn | Main-lake point (12 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 10 to 39 ft | dawn | Deep basin (39 ft) | White tube jig, Airplane jig |
Cliff Lake carries 6 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 39 ft down.
