636-acre lake in Kenora District, Ontario. The lake tops out around 34 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Species by species, here's what the data says the year looks like.
On the chart, Coyston Lake draws 637 acres inside 7.1 miles of shoreline, broken up by 2 islands. The shoreline is moderately structured (index 2) — enough points and pockets to pattern. About 82% 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 1.6 mi with a 1-mi widest point. You'll find it in Kenora District. For a second option, Buddell Lake lies 3 mi west.
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 10 to 34 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.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| 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 (29 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 10 to 34 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (29 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 10 to 34 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (29 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Coyston Lake carries 6 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 29 ft down.
