Rating depth structure for rainbow trout.

9-acre lake in Dufferin County, Ontario. The lake tops out around 8 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 9 acres wrapped in 0.5 miles of bank. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. It sits in Dufferin County. Earl Rowe Lake sits 13 mi east — the closest neighbouring chart.
Early season rainbow trout use the shallows, holding in 2 to 8 ft. Even in summer they hold at 2 to 8 ft; winter keeps them in 2 to 8 ft. Put Shoreline break first on the milk run — a drop-off near 4 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dawn & dusk | Shoreline break (4 ft) | Inline spinner (silver), Small spoon |
| Summer | 2 to 8 ft | dawn & dusk | Shoreline break (4 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 2 to 8 ft | dawn & dusk | Shoreline break (4 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 2 to 8 ft | dawn | Shoreline break (4 ft) | Jigging spoon, Tube jig (white) |
