9-acre lake in Timiskaming District, Ontario. The lake tops out around 28 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 rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Gardner Lake runs 8 acres with 0.4 miles of edge. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. 85% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The water lies in Timiskaming District. The nearest mapped water is Link Lake, 0 mi to the west.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. Midsummer fish sit out in 8 to 28 ft before dropping to 3 to 20 ft for winter. The spot to know is Deep basin, a deep basin in about 20 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 | Shoreline break (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 8 to 28 ft | dawn & dusk | Deep basin (20 ft) | 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 | Deep basin (20 ft) | Small jigging spoon, Tungsten jig + plastic |
Structure-wise the chart holds 3 features, led in depth by Deep basin at roughly 20 ft.
Season dates, license requirements, and size and bag limits for Ontario waters are set by the Ontario fishing regulations (FMZ summary) — and special regulations can apply to Gardner Lake specifically, so confirm the current rules before you fish.
