91-acre lake in Sudbury District, Ontario. The lake tops out around 50 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Here is how the season plays out for each species, straight from the data behind the map.
On the chart, Klemmer Lake draws 91 acres inside 3.2 miles of shoreline. An index of 2.4 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 34% of the surface on the model — that's where the groceries are. End to end it runs roughly 1.3 mi, about 0.2 mi across. You'll find it in Sudbury District. For a second option, Turf Lake lies 4 mi east.
Spring lake whitefish on Klemmer Lake hold shallow, usually 15 to 45 ft. They move out to 15 to 50 ft in summer and finish the year down in 15 to 50 ft. Put Deep basin first on the milk run — a deep basin near 43 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a blade bait vertical or a small jigging spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (23 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 15 to 50 ft | dawn | Deep basin (43 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (23 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 15 to 50 ft | midday & dawn | Deep basin (43 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 6 ft of water that rates prime for northern pike in spring. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
