321-acre lake near Québec. The lake tops out around 89 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Lac Collin draws 321 acres inside 3.2 miles of shoreline. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. Littoral water — the productive band under ~15 ft — makes up 22% of this chart. The basin spans about 1.3 mi end to end and 0.6 mi across at its widest. The water lies in Matawinie MRC.

The spring pattern is a shallow one: brook trout in 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. The spot to know is Main-lake point, a point in about 4 ft of water that rates prime for brook trout in spring. Plan around early morning and the evening in the warm months. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.

|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (4 ft) | Small inline spinner (gold), Tiny spoon |

| Automne | 2 to 15 ft | midday & dawn | Main-lake point (4 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (3 ft) | Small jigging spoon, Tungsten jig + plastic |
The spring pattern is a shallow one: lake trout in 10 to 40 ft. As the season builds they drop to 27 to 89 ft, wintering in 20 to 80 ft. Top water on the chart: Deep basin, a deep basin in the 89 ft range, prime in summer. Time it for early morning. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.

|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Secondary point (10 ft) | Casting spoon over shoals, Jerkbait (shallow) |

Come spring, look for lake whitefish tight to the bank in 15 to 45 ft. Expect a summer slide to 27 to 89 ft, then a winter hold in 25 to 70 ft. Start at Deep basin. It's a deep basin holding about 89 ft of water and rates prime come summer. Prime time lands in early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.

It's a deep basin holding about 89 ft of water and rates prime come summer. Prime time lands in early morning.

Spring walleye on Lac Collin hold shallow, usually 4 to 15 ft. They move out to 15 to 35 ft in summer and finish the year down in 20 to 40 ft. Put Break off the point first on the milk run — a drop-off near 33 ft that grades prime for fall. The feeding windows run the evening and early morning. The summer box starts with a crawler harness on bottom bouncer or a deep crankbait (trolled).
