18-acre lake in Nipissing District, Ontario. The lake tops out around 109 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Glassy Lake draws 18 acres inside 1 miles of shoreline. Index 1.7 on the shoreline: a few honest points and pockets, nothing labyrinthine. Roughly 23% of the water is 15 ft or less as modeled, the band where the food chain lives. Tip to tip the water measures near 0.4 mi. You'll find it in Nipissing District. For a second option, Bell Lake lies 3 mi east.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Top water on the chart: Shallow bay flat, a weed flat in the 6 ft range, good in spring. Time it for early morning and the evening. 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 | Shallow bay flat (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring brown trout on Glassy Lake hold shallow, usually 3 to 25 ft. By summer they slide out to 25 to 60 ft, and by winter most fish are in 5 to 35 ft. The chart's best answer is Break off the point — drop-off, 49 ft, prime for summer. Prime time lands in after dark and early morning. The summer box starts with a spoon at the thermocline or a deep stickbait (night).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (27 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 25 to 60 ft | night & dawn | Break off the point (49 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (27 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | Break off the point (49 ft) | Jigging spoon, Small stickbait (slow) |
