18-acre lake in Algoma District, Ontario. The lake tops out around 3 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. Here's the year, species by species, as the scoring engine sees it.
On the chart, Root River draws 18 acres inside 3.7 miles of shoreline. An index of 6.3 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Call it 1 mi long by 0.5 mi wide at the broadest reach. The water lies in Algoma District. Closest neighbour on DepthScout: Little Lake George, 1 mi east of here.
Start shallow in spring: brook trout sit in 1 to 3 ft that time of year. They don't go far with the seasons — 1 to 3 ft covers summer, 1 to 3 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 3 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 3 ft | dawn & dusk | Main-lake point (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 1 to 3 ft | dawn & dusk | Deep basin (3 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 3 ft | midday & dawn | Main-lake point (3 ft) | Small spoon (orange), Spinner |
| Winter | 1 to 3 ft | dawn | Deep basin (3 ft) | Small jigging spoon, Tungsten jig + plastic |
The spring pattern is a shallow one: rainbow trout in 1 to 3 ft. The depth story barely changes: 1 to 3 ft through summer, 1 to 3 ft in winter. The spot to know is Break off the point, a drop-off in about 1 ft of water that rates prime for rainbow trout in winter. Plan around early morning and the evening in the warm months. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 3 ft | dawn & dusk | Main-lake point (3 ft) | Inline spinner (silver), Small spoon |
| Summer | 1 to 3 ft | dawn & dusk | Break off the point (1 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 1 to 3 ft | dawn & dusk | Main-lake point (3 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 1 to 3 ft | dawn | Break off the point (1 ft) | Jigging spoon, Tube jig (white) |
The spring pattern is a shallow one: chinook salmon in 1 to 3 ft. The depth story barely changes: 1 to 3 ft through summer, 1 to 3 ft in winter. Top water on the chart: Deep basin, a deep basin in the 3 ft range, prime in summer. Time it for early morning and the evening. Summer baits: a flasher + fly (green/white) or a magnum spoon on downrigger gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 3 ft | dawn & dusk | Break off the point (1 ft) | Trolled spoon (orange/gold), Stickbait off planer boards |

| Winter | 1 to 3 ft | midday | Deep basin (3 ft) | Small spoon on a slow troll, Stickbait deep |
In spring, coho salmon run shallow here, mostly 1 to 3 ft. Summer keeps them at 1 to 3 ft, and they winter in 1 to 3 ft. Deep basin is the standout, a deep basin at roughly 3 ft, rated prime for summer coho salmon. Time it for early morning and the evening. You won't need more than a dodger + fly or a medium spoon above the thermocline most summer days.

|---|---|---|---|---|
| Spring | 1 to 3 ft | dawn & dusk | Main-lake point (3 ft) | Small orange dodger + peanut fly, Thin spoon (orange/silver) |
