890-acre lake in Timiskaming District, Ontario. The lake tops out around 25 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 (a transect sounding survey). Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 894 acres wrapped in 10.7 miles of bank, broken up by 7 islands. With a shoreline index of 2.6, this water is all arms and coves — edge habitat well beyond its acreage. Littoral water — the productive band under ~15 ft — makes up 79% of this chart. The basin spans about 2.8 mi end to end and 0.9 mi across at its widest. Timiskaming District claims this one. Skeletonpup Lake sits 2 mi west — the closest neighbouring chart.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.

Spring lake trout on Skeleton Lake hold shallow, usually 6 to 25 ft. Depth-wise the year is flat: 8 to 25 ft in summer, 6 to 25 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 25 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 25 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Break off the point (10 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 8 to 25 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (25 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 5 to 25 ft chart-limited; documented 10 to 50 ft | dusk & dawn | Secondary point (4 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 6 to 25 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (25 ft) | White tube jig, Airplane jig |
In spring, cisco (lake herring) run shallow here, mostly 6 to 25 ft. Summer keeps them at 8 to 25 ft, and they winter in 8 to 25 ft. Spring cisco (lake herring) concentrate at Deep basin, a prime-rated deep basin around 25 ft. Fish it in early morning and you'll meet the bite. You won't need more than a vertical flutter spoon (small) or a drop-shot micro plastic most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 25 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Deep basin (25 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 8 to 25 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (25 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |

| Winter | 8 to 25 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (25 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
The spring pattern is a shallow one: walleye in 4 to 15 ft. As the season builds they drop to 8 to 25 ft, wintering in 8 to 25 ft. Top water on the chart: Break off the point, a drop-off in the 10 ft range, prime in fall. Time it for the evening and early morning. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Secondary point (4 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 8 to 25 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (10 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 8 to 25 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (10 ft) | Jigging rap, Jig + big minnow |
| Winter | 8 to 25 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (25 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: sauger in 4 to 18 ft. Midsummer fish sit out in 8 to 25 ft before dropping to 8 to 25 ft for winter. The spot to know is Deep basin, a deep basin in about 25 ft of water that rates prime for sauger in winter. Plan around early morning and the evening in the warm months. Summer baits: a bottom bouncer + crawler or a 3-way rig with stickbait gets it done.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 18 ft | dawn & dusk | Secondary point (4 ft) | 3/8 oz jig + ringworm, Hair jig + minnow |
| Summer | 8 to 25 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Break off the point (10 ft) | Bottom bouncer + crawler, 3-way rig with stickbait |
| Fall | 8 to 25 ft chart-limited; documented 12 to 35 ft | dusk & dawn | Break off the point (10 ft) | Jig + big minnow, Blade bait |
| Winter | 8 to 25 ft chart-limited; documented 15 to 45 ft | dusk | Deep basin (25 ft) | Heavy jigging spoon, Jig + minnow (vertical) |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 8 to 25 ft, and winter fish settle into 8 to 25 ft. Back-bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.

Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 2 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (10 ft) | Bucktail, Weedless spoon over cabbage |
