Lake depth chart

10-acre lake in Cochrane District, Ontario. The lake tops out around 33 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Ontario MNRF survey of 1974, a decades-old survey (a transect sounding survey). The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 9 acres, worked by 0.5 miles of shoreline. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. Littoral water — the productive band under ~15 ft — makes up 65% of this chart. Cochrane District claims this one. Gurney L. 7 sits 0 mi southeast — the closest neighbouring chart.
Spring brook trout on Gurney L. 8 hold shallow, usually 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Put Deep basin first on the milk run — a deep basin near 29 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Deep basin (29 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shoreline break (11 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 10 to 33 ft. The spot to know is Shallow bay flat, a weed flat in about 6 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm 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 | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (29 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 10 to 33 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (29 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 10 to 33 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (29 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Structure-wise the chart holds 3 features, led in depth by Deep basin at roughly 29 ft.
