86-acre lake in Parry Sound District, Ontario. The lake tops out around 60 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 1970, a decades-old survey (an MNRF lake survey). What the data behind the map says about each species, season by season:
Tea Lake maps at 86 acres behind 2.2 miles of shoreline. A middling shoreline index (1.7) gives it some bays to work without being a maze. 84% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 0.7 mi of water from one end to the other, 0.4 mi at the beam. It sits in Parry Sound District. Its nearest charted neighbour, Island Lake, is 1 mi to the northeast.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Start at Break off the point. It's a drop-off holding about 9 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (1 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (9 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (1 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (9 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring lake trout on Tea Lake hold shallow, usually 10 to 40 ft. By summer they slide out to 18 to 60 ft, and by winter most fish are in 15 to 60 ft. The chart's best answer is Deep basin — deep basin, 60 ft, prime for summer. Prime time lands in early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (9 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 18 to 60 ft | dawn | Deep basin (60 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Break off the point (9 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 15 to 60 ft | dawn | Deep basin (60 ft) | White tube jig, Airplane jig |
