Rating depth structure for brook trout.

19-acre lake in Algoma District, Ontario. The lake tops out around 59 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 2020 (an MNRF lake survey). The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Dry Fly Lake runs 19 acres with 0.7 miles of edge. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. 37% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 0.3 mi. You'll find it in Algoma District. The nearest mapped water is Dobie Lake, 1 mi to the southwest.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Winter brook trout concentrate at Shoreline break, a prime-rated drop-off around 3 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Shoreline break (3 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 | Shoreline break (3 ft) | Small jigging spoon, Tungsten jig + plastic |
Structure-wise the chart holds 4 features, led in depth by Deep basin at roughly 55 ft.
