In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 8 to 26 ft, and winter fish settle into 3 to 20 ft. Deep basin is the standout, a deep basin at roughly 25 ft, rated prime for summer brook trout. Time it for early morning and the evening. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.

|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (11 ft) | Small inline spinner (gold), Tiny spoon |

Spring puts landlocked salmon in skinny water — 1 to 15 ft is the zone. As the season builds they drop to 8 to 26 ft, wintering in 7 to 26 ft. Summer landlocked salmon concentrate at Deep basin, a prime-rated deep basin around 25 ft. Warm-month bites cluster around early morning and the evening. A dodger + streamer down deep or a thin spoon on lead core covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 1 to 15 ft | dawn & dusk | Main-lake point (11 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |

Come spring, look for walleye tight to the bank in 4 to 15 ft. Expect a summer slide to 8 to 26 ft, then a winter hold in 8 to 26 ft. Start at Break off the point. It's a drop-off holding about 17 ft of water and rates prime come fall. Prime time lands in the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | Main-lake point (11 ft) | 1/8 oz jig + minnow, Hair jig |

| Hiver | 8 to 26 ft | dusk & dawn | Deep basin (25 ft) | Jigging spoon + minnow head, Rattle bait |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 8 to 26 ft in summer and finish the year down in 8 to 26 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 5 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 12 ft | midday & dawn | Shallow bay flat (5 ft) | Small jig + curly tail, Perch-pattern micro crank |

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 5 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.
