133-acre lake in Cochrane District, Ontario. The lake tops out around 39 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 132 acres wrapped in 4.2 miles of bank. That shoreline is heavily fingered (development index 2.6) — bays, points and pockets everywhere, which multiplies the fishable edge. About 71% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Tip to tip the water measures near 1.4 mi with a 0.4-mi widest point. Cochrane District claims this one. Its nearest charted neighbour, Butler Lake, is 1 mi to the north.
Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. The chart's best answer is Break off the point — drop-off, 18 ft, prime for summer. Best bite is early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (10 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (18 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (10 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (18 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: cisco (lake herring) sit in 10 to 39 ft that time of year. They don't go far with the seasons — 12 to 39 ft covers summer, 12 to 39 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 33 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a vertical flutter spoon (small) or a drop-shot micro plastic until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 39 ft | dawn & dusk | Deep basin (33 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 12 to 39 ft | dawn | Deep basin (33 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (18 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 12 to 39 ft | dawn | Deep basin (33 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
In spring, walleye run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 12 to 39 ft. Break off the point is the standout, a drop-off at roughly 18 ft, rated prime for fall 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 | Main-lake point (10 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (18 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 39 ft | dusk & night | Break off the point (18 ft) | Jigging rap, Jig + big minnow |
| Winter | 12 to 39 ft | dusk & dawn | Deep basin (33 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: Shallow bay flat, a weed flat in the 5 ft range, prime in spring. 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 (5 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (18 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (33 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (33 ft) | Tungsten jig + spikes, Rattle spoon (small) |
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 12 to 39 ft. If you only fish one area, make it Main-lake point: a point around 10 ft that scores prime in fall. 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 (10 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (18 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (10 ft) | Jerkbait, Blade bait |
| Winter | 12 to 39 ft | midday | Break off the point (18 ft) | Blade bait, Hair jig |
