130-acre lake in Algoma District, Ontario. The lake tops out around 52 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. What the data behind the map says about each species, season by season:
Alva Lake maps at 130 acres behind 2.4 miles of shoreline. With a 1.5 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 37% of the surface on the model — that's where the groceries are. End to end it runs roughly 0.9 mi, about 0.4 mi across. It sits in Algoma District. Its nearest charted neighbour, Lily Pad Lake, is 1 mi to the south.
Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Put Break off the point first on the milk run — a drop-off near 23 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (13 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (23 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (13 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: rock bass sit in 2 to 10 ft that time of year. Summer pushes them deeper, 5 to 20 ft, and winter fish settle into 12 to 30 ft. The spot to know is Main-lake point, a point in about 13 ft of water that rates prime for rock bass in summer. Warm-month bites cluster around the evening. Throw a ned rig (small) or a marabou jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | open water | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | Main-lake point (13 ft) | Ned rig (small), Marabou jig |
| Fall | 8 to 22 ft | midday | Break off the point (23 ft) | Small tube jig, Inline spinner |
