51-acre lake in British Columbia. The lake tops out around 63 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. What the data behind the map says about each species, season by season:
The drawn water covers 51 acres wrapped in 1.8 miles of bank. With a 1.8 development index there's bank structure worth casting at, in moderation. 35% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. The basin spans about 0.5 mi end to end and 0.3 mi across at its widest. East Kootenay Regional District claims this one. If the bite dies, Baynes Lake is 1 mi to the southeast.

Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. The chart's best answer is Main-lake point — point, 16 ft, prime for spring. Best bite is early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (16 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (16 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 15 to 35 ft. Start at Shallow bay flat. It's a weed flat holding about 6 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (6 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (16 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (16 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | open water | Blade bait, Jigging spoon |
Spring rainbow trout on Surveyors Lake hold shallow, usually 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 8 to 40 ft. Put Main-lake point first on the milk run — a point near 16 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (16 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Main-lake point (16 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (16 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Deep basin (54 ft) | Jigging spoon, Tube jig (white) |
Come spring, look for bull trout tight to the bank in 10 to 40 ft. They move out to 19 to 63 ft in summer and finish the year down in 18 to 63 ft. If you only fish one area, make it Deep basin: a deep basin around 54 ft that scores prime in summer. Best bite is early morning and the evening. A trolled plug on downrigger or a heavy jigging 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 | 10 to 40 ft | dawn & dusk | Main-lake point (16 ft) | Large jointed plug, 6" swimbait (kokanee/trout pattern) |
| Summer | 19 to 63 ft chart-limited; documented 30 to 90 ft | dawn & dusk | Deep basin (54 ft) | Trolled plug on downrigger, Heavy jigging spoon |
| Fall | 5 to 35 ft | dawn & dusk | Main-lake point (16 ft) | Large glide bait, Jointed plug |
| Winter | 18 to 63 ft chart-limited; documented 20 to 70 ft | dawn | Deep basin (54 ft) | Heavy spoon (slow lift), Large soft swimbait |
The spring pattern is a shallow one: dolly varden in 1 to 30 ft. As the season builds they drop to 2 to 40 ft, wintering in 8 to 45 ft. Top water on the chart: Main-lake point, a point in the 16 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a small chrome spoon or a baitfish streamer gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 30 ft | dawn & midday | Main-lake point (16 ft) | Small silver spoon, Inline spinner |
| Summer | 2 to 40 ft | dawn & dusk | Main-lake point (16 ft) | Small chrome spoon, Baitfish streamer |
| Fall | 1 to 25 ft | dawn & dusk | Main-lake point (16 ft) | Small spinner, Egg or fry pattern |
| Winter | 8 to 45 ft | midday | Main-lake point (16 ft) | Small slow spoon, Weighted baitfish fly |

Surveyors Lake is about 63 ft (19 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 brook trout, largemouth bass, rainbow trout, bull trout, dolly varden on Surveyors Lake.
Shallow bay flat is the top-rated area: a weed flat in about 6 ft of water that rates prime for largemouth bass in spring. Scroll up to the map for the complete spot list by species and season.
For brook 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.
