363-acre lake in Cariboo Regional District, British Columbia. The lake tops out around 39 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. The rest of this page walks each species through its year, using the map's own scoring.
Fishem Lake maps at 363 acres behind 6.9 miles of shoreline — one island included. An index of 2.6 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 56% of this chart, as modeled. End to end it runs roughly 2.3 mi, about 0.5 mi across. It sits in Cariboo Regional District. Lastman Lake sits 6 mi north — the closest neighbouring chart.
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 39 ft. Put Break off the point first on the milk run — a drop-off near 18 ft that grades prime for winter. 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 | Main-lake point (10 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (18 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (10 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 39 ft | dawn | Break off the point (18 ft) | Jigging spoon, Tube jig (white) |
The spring pattern is a shallow one: lake whitefish in 12 to 39 ft. The depth story barely changes: 12 to 39 ft through summer, 12 to 39 ft in winter. Top water on the chart: Deep basin, a deep basin in the 33 ft range, prime in summer. Time it for early morning. Summer baits: a blade bait vertical or a small jigging spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 12 to 39 ft | midday & dawn | Break off the point (18 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 12 to 39 ft | dawn | Deep basin (33 ft) | Blade bait vertical, Small jigging spoon |
