142-acre lake in Simcoe County, Ontario. The lake tops out around 36 ft. The depth data here comes from the Ontario MNRF survey of 2007 (an MNRF lake survey). Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 142 acres wrapped in 7.2 miles of bank, with 8 islands in the mix. An index of 4.3 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 65% of the surface — that's where the groceries are. Call it 1 mi long by 0.6 mi wide at the broadest reach. Simcoe County claims this one. If the bite dies, Burrows Lake is 2 mi to the west.
When the water first warms, lake trout slide up into 9 to 36 ft. There's no big seasonal slide here — summer means 11 to 36 ft, winter 9 to 36 ft. Start at Deep basin. It's a deep basin holding about 36 ft of water and rates prime come summer. The feeding windows run early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 9 to 36 ft | dawn & dusk | Break off the point (10 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 11 to 36 ft | dawn | Deep basin (36 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 7 to 36 ft | dusk & dawn | Break off the point (10 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 9 to 36 ft | dawn | Deep basin (36 ft) | White tube jig, Airplane jig |
Spring rainbow trout on Horseshoe Lake hold shallow, usually 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 7 to 36 ft. Put Break off the point first on the milk run — a drop-off near 10 ft that grades prime for winter. The feeding windows run early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Break off the point (10 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (10 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Break off the point (10 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 7 to 36 ft | dawn | Break off the point (10 ft) | Jigging spoon, Tube jig (white) |
In spring, walleye run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 11 to 36 ft. Deep basin is the standout, a deep basin at roughly 36 ft, rated prime for winter walleye. Time it for the evening and early morning. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Break off the point (10 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Deep basin (36 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 11 to 36 ft | dusk & night | Break off the point (10 ft) | Jigging rap, Jig + big minnow |
| Winter | 11 to 36 ft | dusk & dawn | Deep basin (36 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Top water on the chart: Deep basin, a deep basin in the 36 ft range, prime in fall. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (36 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (36 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for muskellunge tight to the bank in 3 to 12 ft. They move out to 8 to 25 ft in summer and finish the year down in 15 to 35 ft. If you only fish one area, make it Break off the point: a drop-off around 10 ft that scores prime in fall. Best bite is the evening and early morning. A double-10 bucktail or a topwater (walk-the-dog / creeper) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (1 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Summer | 8 to 25 ft | dusk & dawn | Break off the point (10 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
| Fall | 8 to 30 ft | midday & dusk | Break off the point (10 ft) | Big rubber (Bull Dawg style), 10"+ glide bait |
| Winter | 15 to 35 ft | midday | Deep basin (36 ft) | Large rubber, crawled slow |
When the water first warms, smallmouth bass slide up into 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 11 to 36 ft. If you only fish one area, make it Break off the point: a drop-off around 10 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (1 ft) | Ned rig, Tube jig |
