96-acre lake in Timiskaming District, Ontario. The lake tops out around 10 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 1977, a decades-old survey (an MNRF lake survey). What follows comes from the same scoring engine that paints the spots above.
On the chart, Copper Lake draws 97 acres inside 3.7 miles of shoreline. A development index of 2.7 means a maze of bays and points: far more casting targets than a round bowl of the same size. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Call it 1.4 mi long by 0.4 mi wide at the broadest reach. You'll find it in Timiskaming District. Closest neighbour on DepthScout: Fourbass Lake, 1 mi west of here.
Spring yellow perch on Copper Lake hold shallow, usually 3 to 10 ft. Depth-wise the year is flat: 3 to 10 ft in summer, 3 to 10 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 6 ft that grades prime for fall. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 10 ft | dawn | Deep basin (6 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
