324-acre lake near Québec. The lake tops out around 79 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. Here's the year, species by species, as the scoring engine sees it.
Lac Monroe maps at 324 acres behind 4.2 miles of shoreline. With a 1.7 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 33% of the surface — that's where the groceries are. Call it 2 mi long by 0.5 mi wide at the broadest reach. Les Laurentides MRC claims this one. Its nearest charted neighbour, Lac Lauzon, is 1 mi to the north.

Spring brook trout on Lac Monroe hold shallow, usually 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Put Break off the point first on the milk run — a drop-off near 13 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.

|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (5 ft) | Small inline spinner (gold), Tiny spoon |

Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 24 to 79 ft in summer and finish the year down in 20 to 79 ft. If you only fish one area, make it Deep basin: a deep basin around 78 ft that scores prime in summer. Best bite is early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.

The spring pattern is a shallow one: arctic char in 4 to 15 ft. Midsummer fish sit out in 20 to 60 ft before dropping to 10 to 40 ft for winter. The spot to know is Break off the point, a drop-off in about 13 ft of water that rates prime for arctic char in spring. Plan around early morning in the warm months. Summer baits: a jigging spoon vertical or a tube jig (smelt) gets it done.

Spring puts walleye in skinny water — 4 to 15 ft is the zone. As the season builds they drop to 15 to 35 ft, wintering in 20 to 40 ft. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 13 ft. Warm-month bites cluster around the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.

The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
