161-acre lake in Kenora District, Ontario. The lake tops out around 76 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Gabbro Lake draws 162 acres inside 4.3 miles of shoreline — 2 islands included. With a shoreline index of 2.4, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 22% of the surface on the model — that's where the groceries are. The basin spans about 0.9 mi end to end and 0.8 mi across at its widest. The water lies in Kenora District. For a second option, Walmsley Lake lies 1 mi southwest.
Spring lake whitefish on Gabbro Lake hold shallow, usually 15 to 45 ft. By summer they slide out to 23 to 76 ft, and by winter most fish are in 25 to 70 ft. The chart's best answer is Deep basin — deep basin, 65 ft, prime for summer. Prime time lands in early morning. The summer box starts with a blade bait vertical or a small jigging spoon.
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 | 15 to 45 ft | midday & dawn | open water | Small jig + waxworm, Blade bait (small) |
| Summer | 23 to 76 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (65 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Main-lake point (19 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Deep basin (65 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
When the water first warms, yellow perch slide up into 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 15 to 35 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 6 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow bay flat (6 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | open water | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | open water | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft. Top water on the chart: Shallow bay flat, a weed flat in the 6 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
