Rating depth structure for rainbow trout.

186-acre lake in British Columbia. The lake tops out around 26 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Joanne Lake runs 185 acres with 4.2 miles of edge. That shoreline is heavily fingered (development index 2.2) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 79% of the water is 15 ft or less as modeled, the band where the food chain lives. Tip to tip the water measures near 1.3 mi with a 0.8-mi widest point. The water lies in Fraser-Fort George Regional District. The nearest mapped water is Kaminski Lake, 4 mi to the west.
Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. Warm water sends them out to 7 to 26 ft; cold water stacks them in 5 to 26 ft. Break off the point is the standout, a drop-off at roughly 12 ft, rated prime for winter rainbow trout. Plan around early morning and the evening in the warm months. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 7 to 26 ft chart-limited; documented 8 to 30 ft | dawn & dusk | Break off the point (12 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 7 to 26 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 5 to 26 ft chart-limited; documented 8 to 40 ft | dawn | Break off the point (12 ft) | Jigging spoon, Tube jig (white) |
In spring, kokanee run shallow here, mostly 8 to 26 ft. Summer keeps them at 8 to 26 ft, and they winter in 7 to 26 ft. Spring kokanee concentrate at Deep basin, a prime-rated deep basin around 22 ft. Fish it in early morning and you'll meet the bite. You won't need more than a dodger + pink/orange squid on downrigger or a kokanee bug + corn most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 26 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (22 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 8 to 26 ft chart-limited; documented 30 to 70 ft | dawn | Deep basin (22 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 3 to 26 ft chart-limited; documented 5 to 40 ft | dawn | Deep basin (22 ft) | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 7 to 26 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (22 ft) | Small glow jig + corn or maggot, Tiny spoon |
Early season lake whitefish use the shallows, holding in 8 to 26 ft. Even in summer they hold at 8 to 26 ft; winter keeps them in 8 to 26 ft. Put Deep basin first on the milk run — a deep basin near 22 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a blade bait vertical or a small jigging spoon and you're in the game.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 26 ft chart-limited; documented 15 to 45 ft | midday & dawn | Break off the point (12 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 8 to 26 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (22 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 7 to 26 ft chart-limited; documented 8 to 30 ft | dusk | Break off the point (12 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 8 to 26 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (22 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Spring puts burbot in skinny water — 8 to 26 ft is the zone. Summer fish stay in 8 to 26 ft, and winter fish hold in 7 to 26 ft. Spring burbot concentrate at Deep basin, a prime-rated deep basin around 22 ft. Warm-month bites cluster around after dark and midday. A heavy jig + cut bait covers the summer program.

6 pieces of structure are mapped here — Deep basin, around 22 ft, is the deepest of them.

Joanne Lake is about 26 ft (8 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target rainbow trout, kokanee, lake whitefish, burbot on Joanne Lake. This isn't a survey of the water — none is published for it — but an informed estimate from the species common to the region, narrowed by this water's depth, size and each species' range.
Deep basin is the top-rated area: a deep basin in about 22 ft of water that rates prime for kokanee in spring. The map above holds the full rated-spot list for every species and season.
For rainbow trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Joanne Lake is regulated by the BC freshwater fishing synopsis. Check the official British Columbia regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
