Rating depth structure for walleye.

9,339-acre lake near Descharme Lake. The lake tops out around 166 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. What follows comes from the same scoring engine that paints the spots above.
On the chart, Patterson Lake draws 9,318 acres inside 33.2 miles of shoreline, broken up by 2 islands. That shoreline is heavily fingered (development index 2.5) — bays, points and pockets everywhere, which multiplies the fishable edge. 28% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. The basin spans about 8.3 mi end to end and 3.9 mi across at its widest. You'll find it in Division No. 18. Closest neighbour on DepthScout: Broach Lake, 5 mi northwest of here.
In spring, arctic grayling run shallow here, mostly 2 to 10 ft. Summer pushes them deeper, 3 to 15 ft, and winter fish settle into 8 to 25 ft. Rock reef is the standout, a rock pile at roughly 7 ft, rated prime for spring arctic grayling. Time it for the evening and early morning. You won't need more than a dry fly (parachute adams, elk hair caddis) or a small inline spinner most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dusk | Rock reef (7 ft) | 1/16 oz spinner (silver), Small dry fly (Adams, Griffith's) |
| Summer | 3 to 15 ft | dusk & dawn | Rock reef (7 ft) | Dry fly (parachute Adams, elk hair caddis), Small inline spinner |
| Fall | 6 to 20 ft | midday | Rock reef (7 ft) | Small spoon, Beadhead nymph under indicator |
| Winter | 8 to 25 ft | midday & dawn | Rock reef (7 ft) | Tungsten jig + waxworm, Small jigging spoon (gold) |
Spring puts burbot in skinny water — 25 to 70 ft is the zone. Warm water sends them out to 50 to 120 ft; cold water stacks them in 15 to 60 ft. Offshore hump is the standout, an offshore hump at roughly 21 ft, rated prime for winter burbot. Plan around after dark and midday in the warm months. A heavy jig + cut bait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Offshore hump (21 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 50 to 120 ft | night & midday | Deep basin (141 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Break off the point (75 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Offshore hump (21 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Early season cisco (lake herring) use the shallows, holding in 10 to 40 ft. Summer is a 40 to 80 ft game here, winter a 20 to 60 ft one. The chart's best answer is Offshore hump — offshore hump, 21 ft, prime for winter. Best bite is early morning. Tie on a vertical flutter spoon (small) or a drop-shot micro plastic and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Offshore hump (21 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 40 to 80 ft | dawn | Break off the point (75 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Rock reef (7 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Offshore hump (21 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring puts lake trout in skinny water — 10 to 40 ft is the zone. Warm water sends them out to 50 to 120 ft; cold water stacks them in 20 to 80 ft. Offshore hump is the standout, an offshore hump at roughly 21 ft, rated prime for winter lake trout. Plan around early morning in the warm months. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Sharp break (25 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Break off the point (75 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Rock reef (7 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Offshore hump (21 ft) | White tube jig, Airplane jig |
Early season lake whitefish use the shallows, holding in 15 to 45 ft. Summer is a 40 to 90 ft game here, winter a 25 to 70 ft one. The chart's best answer is Rock reef — rock pile, 7 ft, prime for fall. Best bite is early morning. Tie on a blade bait vertical or a small jigging spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Offshore hump (21 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Break off the point (75 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Rock reef (7 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Offshore hump (21 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Warm water sends them out to 8 to 20 ft; cold water stacks them in 5 to 15 ft. Top water on the chart: Shallow bay flat, a weed flat in the 6 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.
| 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 |
