1,231-acre lake in Strathcona Regional District, British Columbia. The lake tops out around 185 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Species by species, here's what the data says the year looks like.
Brewster Lake maps at 1,231 acres behind 10.3 miles of shoreline, broken up by an island. With a 2.1 development index there's bank structure worth casting at, in moderation. 9% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Figure 3.5 mi of water from one end to the other, 1.2 mi at the beam. It sits in Strathcona Regional District. Merrill Lake sits 3 mi south — the closest neighbouring chart.
Spring puts cutthroat trout in skinny water — 3 to 15 ft is the zone. Warm water sends them out to 10 to 35 ft; cold water stacks them in 10 to 40 ft. Main-lake point is the standout, a point at roughly 46 ft, rated good for winter cutthroat trout. Plan around early morning and the evening in the warm months. A trolled spoon (small) or an inline spinner covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | open water | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Main-lake point (46 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | open water | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Main-lake point (46 ft) | Small jigging spoon, Marabou jig |
Spring kokanee on Brewster Lake hold shallow, usually 10 to 30 ft. By summer they slide out to 30 to 70 ft, and by winter most fish are in 20 to 80 ft. The chart's best answer is Break off the point — drop-off, 83 ft, good for winter. Prime time lands in early morning. The summer box starts with a dodger + pink/orange squid on downrigger or a kokanee bug + corn.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 30 ft | dawn | open water | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 30 to 70 ft | dawn | Break off the point (83 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 5 to 40 ft | dawn | open water | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 20 to 80 ft | dawn | Break off the point (83 ft) | Small glow jig + corn or maggot, Tiny spoon |
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 8 to 40 ft. Put Shallow bay flat first on the milk run — a feeding flat near 6 ft that grades good for spring. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Shallow bay flat (6 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (46 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | open water | Jigging spoon, Tube jig (white) |
Start shallow in spring: dolly varden sit in 1 to 30 ft that time of year. Warm water sends them out to 2 to 40 ft; cold water stacks them in 8 to 45 ft. Top water on the chart: Main-lake point, a point in the 46 ft range, good in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a small chrome spoon or a baitfish streamer until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 30 ft | dawn & midday | open water | Small silver spoon, Inline spinner |
| Summer | 2 to 40 ft | dawn & dusk | Main-lake point (46 ft) | Small chrome spoon, Baitfish streamer |
| Fall | 1 to 25 ft | dawn & dusk | open water | Small spinner, Egg or fry pattern |
| Winter | 8 to 45 ft | midday | Main-lake point (46 ft) | Small slow spoon, Weighted baitfish fly |
