47-acre pond in Ontario. The lake tops out around 20 ft. The depth data here comes from the Ontario MNRF survey of 1976, a decades-old survey (a transect sounding survey). The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Grenadier Pond runs 48 acres with 2.2 miles of edge. An index of 2.3 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. About 82% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 0.8 mi with a 0.3-mi widest point. You'll find it in Toronto. For a second option, Lake Ontario - Toronto Waterfront lies 7 mi east.
When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 6 to 20 ft game here, winter a 6 to 20 ft one. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |

| Fall | 6 to 20 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for northern pike in spring. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |

The spring pattern is a shallow one: smallmouth bass in 3 to 12 ft. Midsummer fish sit out in 6 to 20 ft before dropping to 6 to 20 ft for winter. The spot to know is Secondary point, a point in about 5 ft of water that rates prime for smallmouth bass in fall. Plan around early morning and the evening in the warm months. Summer baits: a drop shot (goby/minnow) or a ned rig gets it done.

|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Secondary point (5 ft) | Ned rig, Tube jig |

| Winter | 6 to 20 ft | midday | Break off the point (3 ft) | Blade bait, Hair jig |
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Warm water sends them out to 8 to 20 ft; cold water stacks them in 6 to 20 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Back-bay flat (11 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
