229-acre lake in Cochrane District, Ontario. The lake tops out around 33 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. Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 227 acres wrapped in 2.6 miles of bank. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. About 74% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Call it 0.8 mi long by 0.6 mi wide at the broadest reach. Cochrane District claims this one. Its nearest charted neighbour, Lake 17H-107, is 1 mi to the northeast.
The spring pattern is a shallow one: lake whitefish in 10 to 33 ft. The depth story barely changes: 10 to 33 ft through summer, 10 to 33 ft in winter. The spot to know is Deep basin, a deep basin in about 28 ft of water that rates prime for lake whitefish in summer. Plan around early morning in the warm months. Summer baits: a blade bait vertical or a small jigging spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 33 ft | midday & dawn | Break off the point (15 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 10 to 33 ft | dawn | Deep basin (28 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (15 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 10 to 33 ft | midday & dawn | Deep basin (28 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
The spring pattern is a shallow one: cisco (lake herring) in 8 to 33 ft. The depth story barely changes: 10 to 33 ft through summer, 10 to 33 ft in winter. The spot to know is Deep basin, a deep basin in about 28 ft of water that rates prime for cisco (lake herring) in spring. Plan around early morning in the warm months. Summer baits: a vertical flutter spoon (small) or a drop-shot micro plastic gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 33 ft | dawn & dusk | Deep basin (28 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 10 to 33 ft | dawn | Deep basin (28 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (15 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 10 to 33 ft | dawn | Deep basin (28 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring puts walleye in skinny water — 4 to 15 ft is the zone. As the season builds they drop to 10 to 33 ft, wintering in 10 to 33 ft. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 15 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 | 4 to 15 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 10 to 33 ft | dusk & dawn | Break off the point (15 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 10 to 33 ft | dusk & night | Break off the point (15 ft) | Jigging rap, Jig + big minnow |
| Winter | 10 to 33 ft | dusk & dawn | Deep basin (28 ft) | Jigging spoon + minnow head, Rattle bait |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 10 to 33 ft. The spot to know is Shallow bay flat, a weed flat in about 4 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 | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (28 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 10 to 33 ft | midday | Deep basin (28 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 10 to 33 ft | midday & dawn | Deep basin (28 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Start at Shallow bay flat. It's a weed flat holding about 4 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 | 2 to 8 ft | midday & dawn | Shallow bay flat (4 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (15 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (15 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (4 ft) | Tip-ups, Large jigging spoon |
