35-acre lake in Cochrane District, Ontario. The lake tops out around 69 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 1981 (an MNRF lake survey). What the data behind the map says about each species, season by season:
The outline encloses 34 acres, worked by 1.2 miles of shoreline. A middling shoreline index (1.5) gives it some bays to work without being a maze. The shallow band under 15 ft claims about 94% of the surface — that's where the groceries are. End to end it runs roughly 0.4 mi, about 0.3 mi across. Cochrane District claims this one. Its nearest charted neighbour, Shirley L., is 0 mi to the west.
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. Shallow bay flat is the standout, a weed flat at roughly 1 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (3 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (3 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (57 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Structure-wise the chart holds 4 features, led in depth by Deep basin at roughly 57 ft.
