114-acre lake in Parry Sound District, Ontario. The lake tops out around 16 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 1972, a decades-old survey (an MNRF lake survey). Here's the year, species by species, as the scoring engine sees it.
On the chart, Mutton Lake draws 113 acres inside 2.6 miles of shoreline. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. End to end it runs roughly 0.9 mi, about 0.4 mi across. The water lies in Parry Sound District. Closest neighbour on DepthScout: Star Lake, 1 mi southeast of here.
When the water first warms, yellow perch slide up into 3 to 12 ft. By summer they slide out to 5 to 16 ft, and by winter most fish are in 5 to 16 ft. If you only fish one area, make it Deep basin: a deep basin around 7 ft that scores prime in fall. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| 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 | 5 to 16 ft | dawn | Deep basin (7 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 16 ft | midday | Deep basin (7 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 16 ft | midday & dawn | Deep basin (7 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. As the season builds they drop to 5 to 16 ft, wintering in 5 to 15 ft. Top water on the chart: Shallow bay flat, a weed flat in the 1 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
| Season | Depth | Best window | Start at | Go-to baits |

The spring pattern is a shallow one: smallmouth bass in 3 to 12 ft. As the season builds they drop to 5 to 16 ft, wintering in 5 to 16 ft. Top water on the chart: Main-lake point, a point in the 1 ft range, prime in fall. Time it for early morning and the evening. Summer baits: a drop shot (goby/minnow) or a ned rig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (1 ft) | Ned rig, Tube jig |
| Summer | 5 to 16 ft | dawn & dusk | Break off the point (1 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 5 to 16 ft | midday & dawn | Main-lake point (1 ft) | Jerkbait, Blade bait |
| Winter | 5 to 16 ft | midday | Break off the point (1 ft) | Blade bait, Hair jig |
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Summer pushes them deeper, 5 to 16 ft, and winter fish settle into 5 to 16 ft. The spot to know is Shallow bay flat, a weed flat in about 1 ft of water that rates prime for largemouth bass in spring. Warm-month bites cluster around early morning and the evening. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |
| Summer | 5 to 16 ft | dawn & dusk | Shallow bay flat (1 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 16 ft | midday | Deep basin (7 ft) | Blade bait, Jigging spoon |
