Rating depth structure for rainbow trout.
Recent public catches load as you reach this section.
65-acre lake in British Columbia. The lake tops out around 21 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. What the data behind the map says about each species, season by season:
The drawn water covers 65 acres wrapped in 2.2 miles of bank. A middling shoreline index (1.9) gives it some bays to work without being a maze. About 86% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. End to end it runs roughly 0.8 mi, about 0.3 mi across. Peace River Regional District claims this one. If the bite dies, Rainbow Lake is 5 mi to the northwest.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.
Official exact-water fish record. The listing documents source-recorded presence, not present abundance or guaranteed catchability.
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. They move out to 6 to 21 ft in summer and finish the year down in 4 to 21 ft. If you only fish one area, make it Break off the point: a drop-off around 9 ft that scores prime in winter. Best bite is 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 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 6 to 21 ft chart-limited; documented 8 to 30 ft | dawn & dusk | Break off the point (9 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 6 to 21 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 21 ft chart-limited; documented 8 to 40 ft | dawn | Break off the point (9 ft) | Jigging spoon, Tube jig (white) |
Spring puts lake whitefish in skinny water — 6 to 21 ft is the zone. Summer fish stay in 6 to 21 ft, and winter fish hold in 6 to 21 ft. Deep basin is the standout, a deep basin at roughly 18 ft, rated prime for summer lake whitefish. Plan around early morning in the warm months. A blade bait vertical or a small jigging spoon covers the summer program.

| Winter | 6 to 21 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (18 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Spring bull trout on Jack Lake hold shallow, usually 5 to 21 ft. Depth-wise the year is flat: 6 to 21 ft in summer, 6 to 21 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 18 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a trolled plug on downrigger or a heavy jigging spoon.
