272-acre lake in Simcoe County, Ontario. The lake tops out around 56 ft. The depth data here comes from the Ontario MNRF survey of 2007 (an MNRF lake survey). Here's the year, species by species, as the scoring engine sees it.
Traced from the shoreline, Tea Lake runs 273 acres with 8.6 miles of edge, broken up by 8 islands. That shoreline is heavily fingered (development index 3.7) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 64% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 2 mi, about 0.8 mi across. The water lies in Simcoe County. For a second option, Mountain Lake lies 1 mi southwest.
When the water first warms, lake whitefish slide up into 15 to 45 ft. By summer they slide out to 17 to 56 ft, and by winter most fish are in 17 to 56 ft. If you only fish one area, make it Deep basin: a deep basin around 54 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.

|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (11 ft) | Small jig + waxworm, Blade bait (small) |

Early season walleye use the shallows, holding in 4 to 15 ft. Summer is a 15 to 35 ft game here, winter a 20 to 40 ft one.

Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
