778-acre lake in British Columbia. The lake tops out around 75 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. What follows comes from the same scoring engine that paints the spots above.
On the chart, John Hart Lake draws 777 acres inside 12.8 miles of shoreline. With a shoreline index of 3.3, this water is all arms and coves — edge habitat well beyond its acreage. Littoral water — the productive band under ~15 ft — makes up 19% of this chart, as modeled. Figure 3.4 mi of water from one end to the other, 1.8 mi at the beam. The water lies in Strathcona Regional District. Closest neighbour on DepthScout: Echo Lake, 4 mi southwest of here.

Spring puts coho salmon in skinny water — 3 to 25 ft is the zone. As the season builds they drop to 30 to 70 ft, wintering in 20 to 60 ft. Summer coho salmon concentrate at Deep basin, a prime-rated deep basin around 64 ft. Warm-month bites cluster around early morning and the evening. A dodger + fly or a medium spoon above the thermocline covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (19 ft) | Small orange dodger + peanut fly, Thin spoon (orange/silver) |
| Summer | 30 to 70 ft | dawn & dusk | Deep basin (64 ft) | Dodger + fly, Medium spoon above the thermocline |
| Fall | 8 to 40 ft | dawn & dusk | Main-lake point (19 ft) | Casting spoon, Spinner (chartreuse) |
| Winter | 20 to 60 ft | midday | Deep basin (64 ft) | Small spoon, slow troll |
Spring cutthroat trout on John Hart Lake hold shallow, usually 3 to 15 ft. They move out to 10 to 35 ft in summer and finish the year down in 10 to 40 ft. Put Main-lake point first on the milk run — a point near 19 ft that grades prime for fall. The feeding windows run early morning and the evening. The summer box starts with a trolled spoon (small) or an inline spinner.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Main-lake point (19 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Main-lake point (19 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (19 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Main-lake point (19 ft) | Small jigging spoon, Marabou jig |
The spring pattern is a shallow one: kokanee in 10 to 30 ft. Midsummer fish sit out in 30 to 70 ft before dropping to 19 to 75 ft for winter. The spot to know is Deep basin, a deep basin in about 64 ft of water that rates prime for kokanee in summer. Plan around early morning in the warm months. Summer baits: a dodger + pink/orange squid on downrigger or a kokanee bug + corn gets it done.
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 30 ft | dawn | open water | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 30 to 70 ft | dawn | Deep basin (64 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 5 to 40 ft | dawn | open water | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 19 to 75 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (64 ft) | Small glow jig + corn or maggot, Tiny spoon |
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Warm water sends them out to 8 to 30 ft; cold water stacks them in 8 to 40 ft. Top water on the chart: Main-lake point, a point in the 19 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (19 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Main-lake point (19 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (19 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | open water | Jigging spoon, Tube jig (white) |
Early season dolly varden use the shallows, holding in 1 to 30 ft. Expect a summer slide to 2 to 40 ft, then a winter hold in 8 to 45 ft. Put Main-lake point first on the milk run — a point near 19 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a small chrome spoon or a baitfish streamer and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 30 ft | dawn & midday | Main-lake point (19 ft) | Small silver spoon, Inline spinner |
| Summer | 2 to 40 ft | dawn & dusk | Main-lake point (19 ft) | Small chrome spoon, Baitfish streamer |
| Fall | 1 to 25 ft | dawn & dusk | Main-lake point (19 ft) | Small spinner, Egg or fry pattern |
| Winter | 8 to 45 ft | midday | Main-lake point (19 ft) | Small slow spoon, Weighted baitfish fly |
