56-acre lake in Peterborough County, Ontario. The lake tops out around 84 ft. The depth data here comes from the Ontario MNRF survey of 1969, a decades-old survey (a transect sounding survey). Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Cavendish Lake draws 57 acres inside 2.1 miles of shoreline, broken up by an island. Index 2 on the shoreline: a few honest points and pockets, nothing labyrinthine. The shallow band under 15 ft claims about 30% of the surface — that's where the groceries are. Figure 0.7 mi of water from one end to the other, 0.3 mi at the beam. The water lies in Peterborough County. Closest neighbour on DepthScout: Beaver Lake, 1 mi northwest of here.
Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Summer pushes them deeper, 25 to 84 ft, and winter fish settle into 20 to 80 ft. The spot to know is Deep basin, a deep basin in about 84 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 40 ft | dawn & dusk | Main-lake point (19 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 25 to 84 ft | dawn | Deep basin (84 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (19 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (84 ft) | White tube jig, Airplane jig |
Spring puts smallmouth bass in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 20 to 45 ft. Fall smallmouth bass concentrate at Main-lake point, a prime-rated point around 19 ft. Warm-month bites cluster around early morning and the evening. A drop shot (goby/minnow) or a ned rig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | open water | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Main-lake point (19 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (19 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (57 ft) | Blade bait, Hair jig |
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 15 to 35 ft. Shallow bay flat is the standout, a weed flat at roughly 2 ft, rated prime for spring largemouth bass. Time it for early morning and the evening. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (19 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (19 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Break off the point (57 ft) | Blade bait, Jigging spoon |
