3,193-acre lake near Nakamun Park. The lake tops out around 65 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What the data behind the map says about each species, season by season:
Drawn out, this is 3,186 acres of water rimmed by 17.3 miles of bank — one island included. An index of 2.2 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. 40% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 4.6 mi, about 1.9 mi across. The water lies in Division No. 13. Closest neighbour on DepthScout: Nakamun Lake, 6 mi southeast of here.
Start shallow in spring: arctic grayling sit in 2 to 10 ft that time of year. Warm water sends them out to 3 to 15 ft; cold water stacks them in 8 to 25 ft. Top water on the chart: Shallow feeding flat, a feeding flat in the 5 ft range, prime in summer. Fish it in the evening and early morning and you'll meet the bite. Throw a dry fly (parachute adams, elk hair caddis) or a small inline spinner until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dusk | Shallow feeding flat (5 ft) | 1/16 oz spinner (silver), Small dry fly (Adams, Griffith's) |
| Summer | 3 to 15 ft | dusk & dawn | Shallow feeding flat (5 ft) | Dry fly (parachute Adams, elk hair caddis), Small inline spinner |
| Fall | 6 to 20 ft | midday | Break off the point (27 ft) | Small spoon, Beadhead nymph under indicator |
| Winter | 8 to 25 ft | midday & dawn | Shallow feeding flat (20 ft) | Tungsten jig + waxworm, Small jigging spoon (gold) |
Start shallow in spring: burbot sit in 20 to 65 ft that time of year. They don't go far with the seasons — 20 to 65 ft covers summer, 15 to 60 ft covers winter. The spot to know is Deep basin, a deep basin in about 65 ft of water that rates prime for burbot in spring. Warm-month bites cluster around after dark and midday. Throw a heavy jig + cut bait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 20 to 65 ft | night & dusk | Deep basin (65 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 20 to 65 ft | night & midday | Deep basin (65 ft) | Heavy jig + cut bait |
| Fall | 20 to 65 ft | night & dusk | Deep basin (65 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Deep basin (65 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
When the water first warms, cisco (lake herring) slide up into 10 to 40 ft. By summer they slide out to 20 to 65 ft, and by winter most fish are in 20 to 60 ft. If you only fish one area, make it Deep basin: a deep basin around 65 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a vertical flutter spoon (small) or a drop-shot micro plastic rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (27 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 20 to 65 ft | dawn | Deep basin (65 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (27 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Deep basin (65 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
When the water first warms, lake whitefish slide up into 15 to 45 ft. By summer they slide out to 20 to 65 ft, and by winter most fish are in 20 to 65 ft. If you only fish one area, make it Deep basin: a deep basin around 65 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (27 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 20 to 65 ft | dawn | Deep basin (65 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (27 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 20 to 65 ft | midday & dawn | Deep basin (65 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 1 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow feeding flat (20 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shoreline point (9 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow feeding flat (5 ft) | Tip-ups, Large jigging spoon |
Early season walleye use the shallows, holding in 4 to 15 ft. Summer is a 15 to 35 ft game here, winter a 20 to 40 ft one. The chart's best answer is Break off the point — drop-off, 27 ft, prime for fall. Best bite is the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Shoreline point (9 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (27 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (27 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Break off the point (27 ft) | Jigging spoon + minnow head, Rattle bait |
