63-acre lake in Simcoe County, Ontario. The lake tops out around 5 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 64 acres wrapped in 2.5 miles of bank. With a shoreline index of 2.3, this water is all arms and coves — edge habitat well beyond its acreage. 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 0.8 mi with a 0.4-mi widest point. Simcoe County claims this one. If the bite dies, Marl Lake is 2 mi to the north.
When the water first warms, splake slide up into 1 to 5 ft. There's no big seasonal slide here — summer means 2 to 5 ft, winter 1 to 5 ft. Start at Break off the point. It's a drop-off holding about 2 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a trolled spoon at the thermocline or a white tube jig (deep) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | dawn & dusk | Main-lake point (5 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 2 to 5 ft | dawn & dusk | Break off the point (2 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 1 to 5 ft | dawn & dusk | Main-lake point (5 ft) | Casting spoon, Jerkbait |
| Winter | 1 to 5 ft | dawn | Break off the point (2 ft) | Jigging spoon tipped with minnow head, Small white tube |
Early season rainbow trout use the shallows, holding in 1 to 5 ft. Even in summer they hold at 1 to 5 ft; winter keeps them in 1 to 5 ft. The chart's best answer is Break off the point — drop-off, 2 ft, prime for winter. Best bite is early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | dawn & dusk | Main-lake point (5 ft) | Inline spinner (silver), Small spoon |
| Summer | 1 to 5 ft | dawn & dusk | Break off the point (2 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 1 to 5 ft | dawn & dusk | Main-lake point (5 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 1 to 5 ft | dawn | Break off the point (2 ft) | Jigging spoon, Tube jig (white) |
Spring puts walleye in skinny water — 1 to 5 ft is the zone. Summer fish stay in 2 to 5 ft, and winter fish hold in 2 to 5 ft. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 2 ft. Warm-month bites cluster around the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | dusk & dawn | Main-lake point (5 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 2 to 5 ft | dusk & dawn | Break off the point (2 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 2 to 5 ft | dusk & night | Break off the point (2 ft) | Jigging rap, Jig + big minnow |
| Winter | 2 to 5 ft | dusk & dawn | Deep basin (5 ft) | Jigging spoon + minnow head, Rattle bait |
Start shallow in spring: yellow perch sit in 1 to 5 ft that time of year. They don't go far with the seasons — 2 to 5 ft covers summer, 2 to 5 ft covers winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| 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) |
Come spring, look for northern pike 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. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage 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) | #5 inline spinner, Spoon (red/white) |
| Summer | 2 to 5 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 2 to 5 ft | midday & dawn | Shallow bay flat (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 2 to 5 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Come spring, look for smallmouth bass 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. Start at Main-lake point. It's a point holding about 5 ft of water and rates prime come fall. Prime time lands in early morning and the evening. A drop shot (goby/minnow) or a ned rig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | dawn & dusk | Main-lake point (5 ft) | Ned rig, Tube jig |
| Summer | 2 to 5 ft | dawn & dusk | Break off the point (2 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 2 to 5 ft | midday & dawn | Main-lake point (5 ft) | Jerkbait, Blade bait |
