Rating depth structure for smallmouth bass.
Recent public catches load as you reach this section.
55-acre lake in British Columbia. The lake tops out around 19 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. What follows comes from the same scoring engine that paints the spots above.
Drawn out, this is 55 acres of water rimmed by 2 miles of bank. The shoreline is moderately structured (index 1.9) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 67% of this chart, as modeled. Call it 0.7 mi long by 0.3 mi wide at the broadest reach. The water lies in Capital Regional District. Closest neighbour on DepthScout: Quarantine Lake, 1 mi southeast of here.

Start shallow in spring: coho salmon sit in 2 to 19 ft that time of year. They don't go far with the seasons — 6 to 19 ft covers summer, 6 to 19 ft covers winter. The spot to know is Deep basin, a deep basin in about 16 ft of water that rates prime for coho salmon in summer. Warm-month bites cluster around early morning and the evening. Throw a dodger + fly or a medium spoon above the thermocline until the fish tell you otherwise.
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 | 2 to 19 ft chart-limited; documented 3 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Small orange dodger + peanut fly, Thin spoon (orange/silver) |
| Summer | 6 to 19 ft chart-limited; documented 30 to 70 ft | dawn & dusk | Deep basin (16 ft) | Dodger + fly, Medium spoon above the thermocline |
| Fall | 4 to 19 ft chart-limited; documented 8 to 40 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Spinner (chartreuse) |
| Winter | 6 to 19 ft chart-limited; documented 20 to 60 ft | midday | Deep basin (16 ft) | Small spoon, slow troll |
When the water first warms, cutthroat trout slide up into 3 to 15 ft. Summer is a 5 to 19 ft game here, winter a 5 to 19 ft one. Start at Break off the point. It's a drop-off holding about 9 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a trolled spoon (small) or an inline spinner rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 5 to 19 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Break off the point (9 ft) | Trolled spoon (small), Inline spinner |
| Fall | 4 to 19 ft chart-limited; documented 5 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Inline spinner |
| Winter | 5 to 19 ft chart-limited; documented 10 to 40 ft | dawn | Break off the point (9 ft) | Small jigging spoon, Marabou jig |
The spring pattern is a shallow one: smallmouth bass in 3 to 12 ft. As the season builds they drop to 6 to 19 ft, wintering in 6 to 19 ft. Top water on the chart: Main-lake point, a point in the 8 ft range, prime in fall. Time it for early morning and the evening. 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 (8 ft) | Ned rig, Tube jig |
| Summer | 6 to 19 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Break off the point (9 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 6 to 19 ft chart-limited; documented 8 to 25 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Blade bait |
| Winter | 6 to 19 ft chart-limited; documented 20 to 45 ft | midday | Break off the point (9 ft) | Blade bait, Hair jig |
In spring, rainbow trout run shallow here, mostly 5 to 19 ft. Summer keeps them at 5 to 19 ft, and they winter in 4 to 19 ft. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 9 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.

Matheson Lake is about 19 ft (6 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 coho salmon, cutthroat trout, smallmouth bass, rainbow trout on Matheson Lake.
Deep basin is the top-rated area: a deep basin in about 16 ft of water that rates prime for coho salmon in summer. The interactive chart above rates every spot for each species and season.
For coho salmon, 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.
