97-acre lake in Muskoka District Municipality, Ontario. The lake tops out around 15 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. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, Pence Lake runs 97 acres with 4.4 miles of edge. An index of 3.2 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Call it 1.4 mi long by 0.4 mi wide at the broadest reach. The water lies in Muskoka District Municipality. For a second option, Rat Lake lies 1 mi southwest.
Spring yellow perch on Pence Lake hold shallow, usually 3 to 12 ft. By summer they slide out to 5 to 15 ft, and by winter most fish are in 5 to 15 ft. The chart's best answer is Deep basin — deep basin, 7 ft, prime for fall. Prime time lands in 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 12 ft | midday & dawn | Back-bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 15 ft | dawn | Deep basin (7 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 15 ft | midday | Deep basin (7 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 15 ft | midday & dawn | Deep basin (7 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Summer pushes them deeper, 5 to 15 ft, and winter fish settle into 5 to 15 ft. Back-bay flat is the standout, a weed flat at roughly 2 ft, rated prime for spring largemouth bass. Time it for early morning and the evening. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Back-bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 5 to 15 ft | dawn & dusk | Back-bay flat (2 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (1 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 5 to 15 ft | midday | Deep basin (7 ft) | Blade bait, Jigging spoon |
When the water first warms, pumpkinseed slide up into 1 to 8 ft. By summer they slide out to 2 to 10 ft, and by winter most fish are in 5 to 15 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 1 ft that scores prime in spring. In summer the feeding windows fall in the evening and early morning. Keep a micro tube or a sponge spider (fly) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (1 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Back-bay flat (2 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Back-bay flat (2 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 15 ft | dawn | Deep basin (7 ft) | Tungsten ice jig + plastic, Tiny spoon |
