104-acre lake in Simcoe County, Ontario. The lake tops out around 24 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 105 acres of water rimmed by 4.4 miles of bank — one island included. With a shoreline index of 3.1, this water is all arms and coves — edge habitat well beyond its acreage. Littoral water — the productive band under ~15 ft — makes up 95% of this chart, as modeled. Figure 1.1 mi of water from one end to the other, 0.6 mi at the beam. You'll find it in Simcoe County. The nearest mapped water is Eastern L., 4 mi to the east.
When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 7 to 24 ft game here, winter a 7 to 24 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 |
| Summer | 7 to 24 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 7 to 24 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 7 to 24 ft | midday & dawn | Deep basin (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: crappie in 2 to 8 ft. Midsummer fish sit out in 7 to 24 ft before dropping to 7 to 24 ft for winter. The spot to know is Deep basin, a deep basin in about 20 ft of water that rates prime for crappie in winter. Plan around early morning and the evening in the warm months. Summer baits: a jig trolled/spider-rigged or a small crankbait (trolled) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 7 to 24 ft | dawn & dusk | Break off the point (11 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Break off the point (11 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 7 to 24 ft | midday | Deep basin (20 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Spring puts brown bullhead in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 3 to 12 ft; cold water stacks them in 7 to 24 ft. Deep basin is the standout, a deep basin at roughly 20 ft, rated prime for winter brown bullhead. Plan around after dark and the evening in the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (3 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (3 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (3 ft) | |
| Winter | 7 to 24 ft | midday | Deep basin (20 ft) |
