16-acre lake in Algoma District, Ontario. The lake tops out around 15 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Ontario MNRF survey of 1970, a decades-old survey (an MNRF lake survey). Here is how the season plays out for each species, straight from the data behind the map.
On the chart, Gervais L. 11 draws 16 acres inside 1 miles of shoreline. Index 1.8 on the shoreline: a few honest points and pockets, nothing labyrinthine. End to end it runs roughly 0.3 mi, about 0.2 mi across. The water lies in Algoma District. For a second option, Supple Lake lies 0 mi south.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. The depth story barely changes: 5 to 15 ft through summer, 2 to 15 ft in winter. The spot to know is Deep basin, a deep basin in about 14 ft of water that rates prime for brook trout in summer. Plan around early morning and the evening in the warm months. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 5 to 15 ft | dawn & dusk | Deep basin (14 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (3 ft) | Small spoon (orange), Spinner |
| Winter | 2 to 15 ft | dawn | Deep basin (14 ft) | Small jigging spoon, Tungsten jig + plastic |
Structure-wise the chart holds 4 features, led in depth by Deep basin at roughly 14 ft.
