12-acre lake in Nipissing District, Ontario. The lake tops out around 13 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Here is how the season plays out for each species, straight from the data behind the map.
On the chart, Little Mountain Lake draws 12 acres inside 0.7 miles of shoreline. Index 1.5 on the shoreline: a few honest points and pockets, nothing labyrinthine. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. End to end it runs roughly 0.3 mi. The water lies in Nipissing District. Closest neighbour on DepthScout: Mountain Lake, 0 mi west of here.
The spring pattern is a shallow one: brook trout in 2 to 13 ft. The depth story barely changes: 4 to 13 ft through summer, 2 to 13 ft in winter. The spot to know is Deep basin, a deep basin in about 11 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 13 ft | dawn & dusk | Shallow bay flat (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 4 to 13 ft | dawn & dusk | Deep basin (11 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
