248-acre lake in Thompson-Nicola Regional District, British Columbia. The lake tops out around 79 ft. The surface is reconstructed from 99 measured spot soundings collected in 1950; water between those measurements is interpolated. Treat the contours between those soundings as a guide, never as navigation. What the data behind the map says about each species, season by season:
Sullivan Lake maps at 248 acres behind 4.8 miles of shoreline — 5 islands included. A development index of 2.2 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 33% of the water is 15 ft or less as modeled, the band where the food chain lives. Figure 1.4 mi of water from one end to the other, 0.4 mi at the beam. It sits in Thompson-Nicola Regional District. Community Lake sits 3 mi southeast — the closest neighbouring chart.
Spring rainbow trout on Sullivan Lake hold shallow, usually 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 8 to 40 ft. The chart's best answer is Break off the point — drop-off, 45 ft, good for winter. Prime time lands in early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (1 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | open water | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (1 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (45 ft) | Jigging spoon, Tube jig (white) |
