573-acre lake in Timiskaming District, Ontario. The lake tops out around 87 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, Sugar Lake runs 575 acres with 11.7 miles of edge. A development index of 3.5 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 41% of the water is 15 ft or less as modeled, the band where the food chain lives. Call it 2.3 mi long by 1.2 mi wide at the broadest reach. You'll find it in Timiskaming District. The nearest mapped water is Goodfish Lake, 1 mi to the northwest.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 26 to 87 ft before dropping to 20 to 80 ft for winter. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 74 ft. Fish it in early morning and you'll meet the bite. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.

|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (22 ft) | Casting spoon over shoals, Jerkbait (shallow) |

Spring lake whitefish on Sugar Lake hold shallow, usually 15 to 45 ft. They move out to 26 to 87 ft in summer and finish the year down in 25 to 70 ft. Put Deep basin first on the milk run — a deep basin near 74 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a blade bait vertical or a small jigging spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (39 ft) | Small jig + waxworm, Blade bait (small) |

When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 15 to 35 ft one. Start at Shallow bay flat. It's a weed flat holding about 6 ft of water and rates prime come spring. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.

The spot to know is Shallow bay flat, a weed flat in about 6 ft of water that rates prime for northern pike in spring. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
