276-acre lake in Thunder Bay District, Ontario. The lake tops out around 23 ft. The depth data here comes from the Ontario MNRF survey of 2008 (an MNRF lake survey). Here is how the season plays out for each species, straight from the data behind the map.
The outline encloses 277 acres, worked by 3.6 miles of shoreline, broken up by 2 islands. A middling shoreline index (1.5) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 59% of this chart. End to end it runs roughly 1 mi, about 0.6 mi across. Thunder Bay District claims this one. If the bite dies, Handley Lake is 1 mi to the southwest.
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 7 to 23 ft, and winter fish settle into 7 to 23 ft. Deep basin is the standout, a deep basin at roughly 22 ft, rated prime for fall yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 7 to 23 ft | dawn | Deep basin (22 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 7 to 23 ft | midday | Deep basin (22 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 7 to 23 ft | midday & dawn | Deep basin (22 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 2 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (2 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 | Main-lake point (5 ft) | Tip-ups, Large jigging spoon |
