463-acre lake in Algoma District, Ontario. The lake tops out around 44 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 464 acres, worked by 12.8 miles of shoreline, with 4 islands in the mix. The 4.2 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Roughly 73% of the water is 15 ft or less as modeled, the band where the food chain lives. Call it 2.6 mi long by 1.2 mi wide at the broadest reach. Algoma District claims this one. Foxwell L. (Hoffman L. 9) sits 1 mi south — the closest neighbouring chart.
Spring brook trout on Patterson Lake hold shallow, usually 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Put Break off the point first on the milk run — a drop-off near 20 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (11 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (20 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (11 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (20 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 13 to 44 ft in summer and finish the year down in 11 to 44 ft. If you only fish one area, make it Deep basin: a deep basin around 37 ft that scores prime in summer. Best bite is early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (11 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 13 to 44 ft | dawn | Deep basin (37 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 9 to 44 ft | dusk & dawn | Main-lake point (11 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 11 to 44 ft | dawn | Deep basin (37 ft) | White tube jig, Airplane jig |
