Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Main-lake point: a point around 1 ft that scores prime in spring. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.

|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (1 ft) | Small inline spinner (gold), Tiny spoon |

Spring lake trout on Lac Quatre Lieues hold shallow, usually 10 to 40 ft. They move out to 35 to 115 ft in summer and finish the year down in 20 to 80 ft. Put Deep basin first on the milk run — a deep basin near 115 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.

When the water first warms, landlocked salmon slide up into 1 to 15 ft. Summer is a 25 to 60 ft game here, winter a 10 to 40 ft one. Start at Main-lake point. It's a point holding about 1 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a dodger + streamer down deep or a thin spoon on lead core rigged through the warm months.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 1 to 15 ft | dawn & dusk | Main-lake point (1 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |

In spring, lake whitefish run shallow here, mostly 15 to 45 ft. Midsummer fish sit out in 40 to 90 ft before dropping to 25 to 70 ft for winter. Spring lake whitefish concentrate at Feeding flat, a prime-rated feeding flat around 24 ft. Fish it in early morning and you'll meet the bite. You won't need more than a blade bait vertical or a small jigging spoon most summer days.

|---|---|---|---|---|
| Printemps | 15 to 45 ft | midday & dawn | Feeding flat (24 ft) | Small jig + waxworm, Blade bait (small) |
