47-acre lake in Waterloo Regional Municipality, Ontario. The lake tops out around 5 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Deans Lake runs 48 acres with 1.3 miles of edge. Nearly circular (index 1.3), so the story is the bottom, not the bank. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Tip to tip the water measures near 0.5 mi with a 0.2-mi widest point. You'll find it in Waterloo Regional Municipality. For a second option, Puslinch Lake lies 9 mi northeast.
Come spring, look for yellow perch tight to the bank in 1 to 5 ft. Through summer count on 2 to 5 ft; the winter hold is 2 to 5 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 5 ft | dawn | Deep basin (5 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 5 ft | midday | Deep basin (5 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 5 ft | midday & dawn | Deep basin (5 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: largemouth bass in 1 to 5 ft. The depth story barely changes: 2 to 5 ft through summer, 2 to 5 ft in winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for largemouth bass in spring. Plan around early morning and the evening in the warm months. Summer baits: a texas-rigged 10" worm or a deep-diving crankbait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 2 to 5 ft | dawn & dusk | Shallow bay flat (3 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 1 to 5 ft | midday & dawn | Main-lake point (3 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 2 to 5 ft | midday | Break off the point (5 ft) | Blade bait, Jigging spoon |
Early season rock bass use the shallows, holding in 1 to 5 ft. Even in summer they hold at 1 to 5 ft; winter keeps them in 2 to 5 ft. The chart's best answer is Main-lake point — point, 3 ft, prime for summer. Best bite is the evening. Tie on a ned rig (small) or a marabou jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | midday & dawn | Main-lake point (3 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 1 to 5 ft | dusk | Main-lake point (3 ft) | Ned rig (small), Marabou jig |
| Fall | 2 to 5 ft | midday | Break off the point (5 ft) | Small tube jig, Inline spinner |
| Winter | 2 to 5 ft | midday | Deep basin (5 ft) | Tungsten jig + plastic, Small spoon + spike |
Early season pumpkinseed use the shallows, holding in 1 to 5 ft. Even in summer they hold at 1 to 5 ft; winter keeps them in 2 to 5 ft. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is the evening and early morning. Tie on a micro tube or a sponge spider (fly) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 1 to 5 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 1 to 5 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
