37-acre lake in Muskoka District Municipality, Ontario. The lake tops out around 20 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, South Nelson Lake runs 37 acres with 1.5 miles of edge. Index 1.8 on the shoreline: a few honest points and pockets, nothing labyrinthine. 92% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. The basin spans about 0.6 mi end to end and 0.2 mi across at its widest. You'll find it in Muskoka District Municipality. The nearest mapped water is Upper Centre Nolan L., 0 mi to the north.
Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is a 6 to 20 ft game here, winter a 6 to 20 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 6 to 20 ft | dawn | Deep basin (17 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 20 ft | midday | Deep basin (17 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (17 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for pumpkinseed tight to the bank in 1 to 8 ft. They move out to 2 to 10 ft in summer and finish the year down in 6 to 18 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is the evening and early morning. A micro tube or a sponge spider (fly) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Deep basin (17 ft) | Tungsten ice jig + plastic, Tiny spoon |
Start shallow in spring: brown bullhead sit in 2 to 8 ft that time of year. Warm water sends them out to 3 to 12 ft; cold water stacks them in 6 to 20 ft. Top water on the chart: Deep basin, a deep basin in the 17 ft range, prime in winter. Fish it in after dark and the evening and you'll meet the bite.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (3 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (3 ft) | |
| Fall | 5 to 15 ft | dusk | Deep basin (17 ft) | |
| Winter | 6 to 20 ft | midday | Deep basin (17 ft) |
