756-acre lake near Québec. The lake tops out around 57 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. What the data behind the map says about each species, season by season:
The outline encloses 756 acres, worked by 8.2 miles of shoreline. A middling shoreline index (2.1) gives it some bays to work without being a maze. About 65% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 2.7 mi with a 1.5-mi widest point. La Vallée-de-la-Gatineau MRC claims this one. Its nearest charted neighbour, Lac Jannée, is 4 mi to the southeast.

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 7 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 (7 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (8 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (7 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Break off the point (8 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring lake trout on Lac Retty hold shallow, usually 10 to 40 ft. They move out to 17 to 57 ft in summer and finish the year down in 14 to 57 ft. Put Deep basin first on the milk run — a deep basin near 54 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.

Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 54 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.

The spring pattern is a shallow one: walleye in 4 to 15 ft. As the season builds they drop to 15 to 35 ft, wintering in 20 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 8 ft range, prime in fall. Time it for the evening and early morning. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
