217-acre lake in Cochrane District, Ontario. The lake tops out around 39 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Here's the year, species by species, as the scoring engine sees it.
There are 3.9 miles of drawn shoreline to work. A development index of 2.6 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 90% of the water is 15 ft or less, the band where the food chain lives. Figure 0.9 mi of water from one end to the other, 0.5 mi at the beam. You'll find it in Cochrane District. Closest neighbour on DepthScout: Boyle Lake 36, 1 mi south of here.
Come spring, look for walleye tight to the bank in 4 to 15 ft. Expect a summer slide to 15 to 35 ft, then a winter hold in 12 to 39 ft. Start at Deep basin. It's a deep basin holding about 38 ft of water and rates prime come winter. Prime time lands in the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (4 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Deep basin (38 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 39 ft | dusk & night | Deep basin (38 ft) | Jigging rap, Jig + big minnow |
| Winter | 12 to 39 ft | dusk & dawn | Deep basin (38 ft) | Jigging spoon + minnow head, Rattle bait |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 15 to 35 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 4 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| 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 | Break off the point (6 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (38 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (38 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Warm water sends them out to 8 to 20 ft; cold water stacks them in 5 to 15 ft. Top water on the chart: Shallow bay flat, a weed flat in the 4 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.
| 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 (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (6 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 |
