Rating depth structure for rainbow trout.
Recent public catches load as you reach this section.
23-acre lake in British Columbia. The lake tops out around 18 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. What follows comes from the same scoring engine that paints the spots above.
Obert Lake maps at 23 acres behind 0.7 miles of shoreline. At index 1 the outline is almost a bowl — read the depth changes, not the shoreline. Littoral water — the productive band under ~15 ft — makes up 85% of this chart, as modeled. Call it 0.3 mi long by 0.2 mi wide at the broadest reach. It sits in Fraser-Fort George Regional District. Its nearest charted neighbour, Shell Lake, is 1 mi to the west.
Come spring, look for rainbow trout tight to the bank in 5 to 18 ft. Through summer count on 5 to 18 ft; the winter hold is 4 to 18 ft. Start at Shoreline break. It's a drop-off holding about 8 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
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 18 ft chart-limited; documented 5 to 20 ft | dawn & dusk | Shoreline break (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 5 to 18 ft chart-limited; documented 8 to 30 ft | dawn & dusk | Shoreline break (8 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 5 to 18 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Shoreline break (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 18 ft chart-limited; documented 8 to 40 ft | dawn | Shoreline break (8 ft) | Jigging spoon, Tube jig (white) |
When the water first warms, kokanee slide up into 5 to 18 ft. There's no big seasonal slide here — summer means 5 to 18 ft, winter 5 to 18 ft. If you only fish one area, make it Deep basin: a deep basin around 15 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a dodger + pink/orange squid on downrigger or a kokanee bug + corn rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 18 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (15 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 5 to 18 ft chart-limited; documented 30 to 70 ft | dawn | Deep basin (15 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 2 to 18 ft chart-limited; documented 5 to 40 ft | dawn | Deep basin (15 ft) | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 5 to 18 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (15 ft) | Small glow jig + corn or maggot, Tiny spoon |
Spring puts lake whitefish in skinny water — 5 to 18 ft is the zone. Summer fish stay in 5 to 18 ft, and winter fish hold in 5 to 18 ft. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 15 ft. Warm-month bites cluster around early morning. A blade bait vertical or a small jigging spoon covers the summer program.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 18 ft chart-limited; documented 15 to 45 ft | midday & dawn | Shoreline break (8 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 5 to 18 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (15 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 5 to 18 ft chart-limited; documented 8 to 30 ft | dusk | Shoreline break (8 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 5 to 18 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (15 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Early season burbot use the shallows, holding in 5 to 18 ft. Even in summer they hold at 5 to 18 ft; winter keeps them in 5 to 18 ft. Put Deep basin first on the milk run — a deep basin near 15 ft that grades prime for spring. In summer the feeding windows fall in after dark and midday. Tie on a heavy jig + cut bait and you're in the game.

Structure-wise the chart holds 4 features, led in depth by Deep basin at roughly 15 ft.

Obert Lake is about 18 ft (5 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 Obert 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 15 ft of water that rates prime for kokanee in spring. Every other rated spot, per species and season, is on the map above.
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 Obert 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.
