795-acre lake near Peace, BC. The lake tops out around 149 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
The chart traces 9.8 miles of shoreline here. That shoreline is heavily fingered (development index 3.5) — bays, points and pockets everywhere, which multiplies the fishable edge. About 9% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 3.2 mi, about 0.5 mi across. The water lies in Stikine Region. For a second option, Tucho Lake lies 23 mi northwest.
Start shallow in spring: arctic grayling sit in 2 to 10 ft that time of year. Warm water sends them out to 3 to 15 ft; cold water stacks them in 8 to 25 ft. Top water on the chart: Shallow bay flat, a feeding flat in the 15 ft range, prime in summer. Fish it in the evening and early morning and you'll meet the bite. Throw a dry fly (parachute adams, elk hair caddis) or a small inline spinner until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dusk | Back-bay flat (3 ft) | 1/16 oz spinner (silver), Small dry fly (Adams, Griffith's) |
| Summer | 3 to 15 ft | dusk & dawn | Shallow bay flat (15 ft) | Dry fly (parachute Adams, elk hair caddis), Small inline spinner |
| Fall | 6 to 20 ft | midday | Break off the point (33 ft) | Small spoon, Beadhead nymph under indicator |
| Winter | 8 to 25 ft | midday & dawn | Shallow bay flat (15 ft) | Tungsten jig + waxworm, Small jigging spoon (gold) |
Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Summer pushes them deeper, 50 to 120 ft, and winter fish settle into 20 to 80 ft. The spot to know is Deep basin, a deep basin in about 129 ft of water that rates prime for lake trout in summer. Warm-month bites cluster around early morning. Throw a white tube jig (deep) or a magnum spoon on downrigger until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (22 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Deep basin (129 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (22 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (33 ft) | White tube jig, Airplane jig |
When the water first warms, lake whitefish slide up into 15 to 45 ft. By summer they slide out to 40 to 90 ft, and by winter most fish are in 25 to 70 ft. If you only fish one area, make it Break off the point: a drop-off around 33 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (33 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Break off the point (33 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Main-lake point (22 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Break off the point (33 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
