306-acre lake near Québec. The lake tops out around 90 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. The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Lac Gregory draws 306 acres inside 3.1 miles of shoreline. Nearly circular (index 1.2), so the story is the bottom, not the bank. Littoral water — the productive band under ~15 ft — makes up 31% of this chart. End to end it runs roughly 1.2 mi, about 0.6 mi across. You'll find it in La Jacques-Cartier MRC. For a second option, Lac Etheleen lies 2 mi northeast.

The spring pattern is a shallow one: brook trout in 2 to 15 ft. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Top water on the chart: Main-lake point, a point in the 7 ft range, prime in spring. Time it for early morning and the evening. 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 (7 ft) | Small inline spinner (gold), Tiny spoon |

The spring pattern is a shallow one: lake trout in 10 to 40 ft. Midsummer fish sit out in 27 to 90 ft before dropping to 20 to 80 ft for winter. The spot to know is Deep basin, a deep basin in about 90 ft of water that rates prime for lake trout in summer. Plan around early morning in the warm months. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.
