116-acre lake in Okanagan-Similkameen Regional District, British Columbia. The lake tops out around 27 ft. The depth chart comes from British Columbia Fish and Wildlife Branch bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, Tugulnuit Lake runs 116 acres with 2 miles of edge. Nearly circular (index 1.3), so the story is the bottom, not the bank. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 0.7 mi end to end and 0.4 mi across at its widest. You'll find it in Okanagan-Similkameen Regional District. Closest neighbour on DepthScout: Gallagher Lake, 3 mi north of here.
In spring, burbot run shallow here, mostly 8 to 27 ft. Summer keeps them at 8 to 27 ft, and they winter in 7 to 27 ft. Spring burbot concentrate at Deep basin, a prime-rated deep basin around 16 ft. Fish it in after dark and midday and you'll meet the bite. You won't need more than a heavy jig + cut bait most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 27 ft chart-limited; documented 25 to 70 ft | night & dusk | Deep basin (16 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 8 to 27 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (16 ft) | Heavy jig + cut bait |
| Fall | 8 to 27 ft chart-limited; documented 30 to 80 ft | night & dusk | Deep basin (16 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 7 to 27 ft chart-limited; documented 15 to 60 ft | night & dusk | Deep basin (16 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Warm water sends them out to 8 to 20 ft; cold water stacks them in 8 to 27 ft. Top water on the chart: Shallow bay flat, a weed flat in the 1 ft range, good in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | open water | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (1 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 8 to 27 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (16 ft) | Blade bait, Jigging spoon |
The spring pattern is a shallow one: smallmouth bass in 3 to 12 ft. Midsummer fish sit out in 8 to 27 ft before dropping to 8 to 27 ft for winter. The spot to know is Deep basin, a deep basin in about 16 ft of water that rates good for smallmouth bass in winter. Plan around early morning and the evening in the warm months. Summer baits: a drop shot (goby/minnow) or a ned rig gets it done.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (1 ft) | Ned rig, Tube jig |
| Summer | 8 to 27 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Break off the point (1 ft) | Drop shot (goby/minnow), Ned rig |

| Winter | 8 to 27 ft chart-limited; documented 20 to 45 ft | midday | Deep basin (16 ft) | Blade bait, Hair jig |
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Summer pushes them deeper, 7 to 27 ft, and winter fish settle into 5 to 27 ft. Deep basin is the standout, a deep basin at roughly 16 ft, rated prime for winter rainbow trout. Time it for early morning and the evening. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.

| Winter | 5 to 27 ft chart-limited; documented 8 to 40 ft | dawn | Deep basin (16 ft) | Jigging spoon, Tube jig (white) |
When the water first warms, walleye slide up into 4 to 15 ft. By summer they slide out to 8 to 27 ft, and by winter most fish are in 8 to 27 ft. If you only fish one area, make it Deep basin: a deep basin around 16 ft that scores prime in winter. In summer the feeding windows fall in the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.

Spring lake whitefish on Tugulnuit Lake hold shallow, usually 8 to 27 ft. Depth-wise the year is flat: 8 to 27 ft in summer, 8 to 27 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 16 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a blade bait vertical or a small jigging spoon.

Tugulnuit Lake is about 27 ft (8 m) deep at its deepest point. The depth chart comes from British Columbia Fish and Wildlife Branch bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Anglers target burbot, largemouth bass, smallmouth bass, rainbow trout, walleye, lake whitefish, black bullhead on Tugulnuit Lake.
Deep basin is the top-rated area: a deep basin in about 16 ft of water that rates prime for burbot in spring. Scroll up to the map for the complete spot list by species and season.
For burbot, the summer bite is best in after dark and midday. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
